TEXAS INSTRUM ENTS INCORPO RATED

A scientific experime nt in a rock quarry near Washingt on, D. C . .1 n

1919, and a test party - probably the fir st field seismogr aph party of its kind - shooting its first profile in a stream bed near Oklahom a City in 1921 set in motion a series of events that have built Texas Instrume nts Incorpor ated. TI is a research , manufact uring and engineeri ng organiza tion today employin g 2300 people and which grossed approxim ately twenty-s ix million dollars in s ale s in 1 9 5 3. Thirty-th ree years ago, as members of this test party in the Arbuckle Mountain s proved ability of the seismogr aph method of geophysi cal explorati on to obtain useful informat ion from the subsurfa ce, they were laying the founda-­ tions for Dallas• present leadersh ip in the electroni cs industry. The designer of the geophysi cal equipmen t used, and leader of the test party, was Dr. J. C. Karcher (now presiden t of Concho Petroleu m Com­ pany), who together with geophysi cist Eugene McDerm ott was later to found Geophysi cal Service Inc.

This organiza tion has taken the name of GSI to the

ends of the earth in the search for geologic structure s favorable for oil accumula tion.

Texas Instrume nts Incorpor ated evolved from the growth of

GSI, and today the products of TI range from tiny transisto rs (it takes twenty­ eight TI transisto rs to weigh an ounce) to a TI shot hole drill which weighs 45,000 pounds mounted on a four-whe el trailer ready for shipment to Saudi Arabia.

Perhaps, better than any other of its many products, TI transistors represent the organization's research and manufacturing teamwork, its manufacturing know-how, and its ability to cope with top manufacturing competition. 11

The transistor and its minute relatives will almost certainly

stimulate greater changes in commerce and industry than reaction motors, synthetic fibers, or even atomic energy 11 , Fortune magazine predicted in a 1953 issue. TI is manufacturing transistors in competition with some of the largest industrial organizations of the nation.

Utilizing all the techniques of

mass industry within its comparatively modest operation 1 TI is definitely not coming out second best. When a corporate charter was issued to Geophysical Service in May, 1930, the company became the first known independent geophysical service specializing in reflection seismograph surveys.

As performance proved

the value of GSI1s services, its activities grew steadily both in volume and geographical coverage.

In 1931, GSI began its first explorations outside

the United States ... in Mexico.

Canada came next in 1932.

overseas, GSI entered Venezuela in 1934.

Then, expanding

In most of the oil provinces of the

world GSI parties were called in to conduct surveys-in Colombia, Ecuador, Saudi Arabia, Java, Sumatra, India~ Brazil, Spain and Portuguese West Africa-adding to the fund of seismograph experience they continued to build up in North America.

In 1953, this experience passed the 500 crew-year mark.

As GSI expanded its world-wide search for oil, Dallas continued to expand as an oil center.

Supply companies moved in.

Major and independ­

ent production, refining, and service organizations grew.

GSI' s growth

gives prime example of how the supply needs of one industry provide the Precision and accuracy were the keynote of

seeds of growth for another.

At GSI' s beginning no other source of supply

As GSI grew, and as geophysical exploration became

progressively more difficult and work locations more remote, the need for rugged, portable, more efficient, fully climate-proof equipment became increasingly acute. GSI from the beginning recognized this problem and actively supported research and development. toward this activity.

Today, the maximum possible effort is directed

Working together in laboratory and testing facilities

probably unmatched in size and scope in the geophysical industry, scientists of Texas Instruments and GSI carry forward today's program.

Geophysicists

and engineers constantly use the results of development to devise new apparatus and improve existing equipment. Out of this background has developed the organization known as Texas Instruments - now applying modern engineering and manufacturing techniques to a wide variety of components, units, and systems for civilian and military use.

Geophysical exploration instruments, heavy equipment, and systems

make up a large part of TI' s current commercial production.

Formerly

available only to Geophysical Service Inc. and its .international affiliates, many of these items are now offered to all users in the petroleum industry. The range of TI products and their potential use can perhaps be appreciated only by those with a technical background in the .industries concerned - but they point up future refinements not only in oil exploration but in the field of military and civilian electronics, and the great range of precision products that may form the heart and brain of tomorrow's in­ dustry. TI' s components production includes: grown junction and point­ contact transistors, transformers, filters, chokes, toroidal coils, con­ densers, pulse networks, antennas, optical components, and quartz springs. TI units include: recording oscillographs, seismometers, amplifiers, blasters, log-level indicators, gravity meters, seismic radio receivers, ink writing recording instruments, and portable shot-hole rigs.

TI systems

include complete geophysical exploration systems and sonar, magnetic, and radar air -borne electronic systems. Transistors alone may form the basis for a whole new industry. Transistors are being heralded as the harbingers of wrist radios, portable television sets, giant digital computers, matchbook-size hearing aids, and tiny gadgets almost beyond the realm of our present-day imagination.

In

circuits where transistors replace vacuum tubes, the problems of heat and glass breakage and excessive power requirements are eliminated. can be "packed together like sardines".

Transistors

A car radio, for instance, may be

made one-tenth the size of present radios with practically no drain on the

car battery except for the dial light.

been determined - some being "life tested 11 have passed the fifth year. transistors will not need frequent replacement.

Thus,

In the future, they will be

wired into the circuit permanently with no need for expensive and space consuming sockets. Today - the Texas Instruments organization is active in electronics marketing as well as research, engineering and manufacturing .

In addition

to direct industry sales by TI, mill and geophysical supplies and electronic parts and instruments are distributed in Dallas, Fort Worth and Tulsa through Engineering Supply Company, its distribution affiliate, which will shortly move to a new 25, 000 square foot building on Denton Drive. TI recently acquired Houston Technical Laboratories, manufacturers of gravity meters and optical components.

TI' s related exploration companies

cover the world.

It .is publicly owned with its stock listed on the New York

Stock Exchange.

Its officials forecast a continuation in sales volume increase

for 1954. Perhaps the key to this home-based, Dallas industrial success story lies in its creative management policies and in its shop slogan: Not Harder".

"Work Smarter,

TI and its associated companies are working smarter in one of

the most highly competitive fields in the nation's industry.

It is successfully

matching its research, development, engineering, and manufacturing knowhow with the top industrial organizations of the nation.

Its over -all organiza­

tion from research to marketing is integrated with all other divisions to compete in the international business world.

INDUSTRIAL N .E WS RELEASE

SILICON TRANSISTORS IN PRODUCTION!

DALLAS, Texas, May 10 -- A revolutionary new electronic product-long predicted and awaited-- became a reality today with the announcement by Texa s Instruments Incorporated of the start of commercial production on s ilicon transistors.

By using silicon instead of germanium, the initial

commercial silicon transistor immediately raises power outputs and doubles operating temperatures! The potential application of this entirely new transistor is so great that major electronics firms have been conducting silicon experiments for s ome time .

Texa s Instruments--a leading ge r manium transistor manu-

facturer--is the first to succeed in placing the new silicon transistor into c ommercial production. Until now, the greate s t disadvantages of transist6r s have been their performa nce varia tion with temperature change and their low power outputs. All previ ous produc t i on units h a ve used germanium, a rare and expensive but more easily worked material. Si licon -- next to oxygen the earth's most common element--long has been known to possess s uperior temperature stability and power handling characteristics .

But up until now, the difficulties of purifying,

11

growing 11

a single large crystal, and fabricating silicon transistors have kept them laboratory devices , unreproducible on a production-line basis.

{more)

Page 2 silicon transistor Texas Instruments--and many other leadi ng electronics firms -- have been producing transistors made from germanium for over a year.

Two

months ago, the company began production of a simple single crystal silicon semiconductor device -- a silicon alloyed junction diode used for rectification-­ experience with which led to placing the silicon tr i ode transistor into production. This first production silicon trans istor is of "grown junction" construetion -- as distinguished from alloyed junction or point contact construction also used in transistor manufacture.

In grown junction transistors, the

contact between semiconductor materials of dissimilar current carrying characteristics is "grown" right into the semiconductor crystal, instead of being made mechanically. Texas Instruments -- a leading transistor manufacturer -- also specializes in grown junction construction for its germanium transistors, on the basis that this design provides superior electrical and mechanical characteristics. The silicon transistor is a direct outgrowth of the work of Tl's Materials and Components Research Section, headed by Dr. Gordon K. Teal, assistant vice president.

The details of the new development were presented in two

technical papers by Texas Instruments scientists. A paper by Drs. Willis A. Adcock, Morton E. Jones and Messers. Jay W . Thornhill, Edmund D . Jackson -• all of whom collaborated in the development -- was presented to a technical journal for publ~cation.

(more)

Dr. Teal, who

Page 3 silicon transistor

directed the research, presented another paper on the development before the National Conference on A irborne Electronics of the I. R. E. in Dayton, Ohio on Monday, May 10. The amplification ability of germanium transistors varies greatly as temperatures rise above room leve l.

Heat dis s ipation in complex commercial

and military electronic equipment is a major problem . • . and. one which has so far limited the application of germanium transistors .

The new silicon

transistors operate with little change up to 150° Centigrade (302° Fahrenheit), well above the temperature of boiling water . Development and commerc ial availability of a silicon transistor thus radically broadens the heretofore limited field of application for transistors. ;Even with the former handicaps of low power output and high temperature sensitivity, the substitution of tran sistors for vacuum tubes has been making great headway because of advantage s in size, power consumption, and reliability.

Hearing aids have been the largest single user. with the combination

NEW TRANSISTOR WILL SHRINK ELECTRONIC II BRAINS"

DALLAS, Texa s, May 10 -- Electronic 11 bra.ins 11 approaching the human bra.in in .scope and reliability ca.me much closer to reality today with the announcement by Texas Instruments Incorporated of the first commercial production of silicon transistors . . . kernel-sized substitutes for vacuum tubes.

By using silicon ins t ead of germanium, the initial commercial

silic on transi stor immediately raises power outputs and doubles operating temperatures! The potential application of this entirely new transistor is so great that America's major electronics firms have been conducting silicon experiments for some time.

Texas Instruments -- a leading germanium

transistor manufacturer -- is the first to succeed in placing the new silicon transistor into commercial production.

The commercial availa-

bility of the revolutionary new high power and practically heat-independent transistor was announced today hy Texas Instruments simultaneously at its main plant here and at an Institute of Radio Engineers meeting in Dayton, Ohio. Instead of the vacuum tube's complex, bulky, fragile construction, transistors use a flea-sized piece of solid semiconductor (neither conductor nor insulator) material to amplify, control, and switch electrical impulses. Transistors a.re truly a

flea-power 11 device, 100, 000 of them consuming

no more power than one ordinary vacuum tube.

Texas Instruments and many other leading electronics firms for several years have been manufacturing the bny transistors made from germanium .

Germanium, a rare and expensive but more easily worked

material, has the disadvantages of low power output and great performance variation with temperature change . The new silicon transis tor operates with little change a.t over 300 degrees Fahrenheit, almost 100 degrees above boiling water .

Transistors

now can be used in the most complicated and complex electronic equipments, where the heat generated by other components has formerly limited the use of germanium transistors. Today's huge e).ectronic "brains" now occupy whole rooms, consume great amounts of electricity, and require large cooling systems because of the heat generated by their thousan ds of vacuum tubes .

By using silicon

transistors, electronic "brains" can be s hrunk to a manageable size, requiring much less power , and having increased reliability . The electronic "brains" in today's supersonic military planes and missiles control almost all functions and account for much valuable space and weight . Not only will silicon transistors make the equipment more reliable and save much space and weight by miniaturizing the electrical amplifying and controlling elements , but much associated equipment also can be made smaller because of lower power demand.

Even with currently-used germani um 's handicaps . the sub s titution of transistors for vacuum tubes has been m a k ing great hea dway be cau s e of the transistor's advantages in size , power consum ption, and re liab ility . Hearing aids have so far been the lar ge st single user , with the c o mbi nation of a wide range of simpler commer cial and m ilitary appli ations coming close behind.

Transistors already have m ade wristwatch and pocket r a dios

conimonplace among engineers. The silicon transistor is a d i rect outgrowt h of the work of th e Texas Instruments Materials and Components Re s e a r ch Section, h e aded by Dr. Gordon K. Teal, assistant vice pre s i d e nt ,

Dr . Teal today present e d

a scientific paper describing the fir st production mode l silicon transistor before the National Conference on Airborne E lectronics of the I. R . E . in Dayton, Ohio. Silicon -- next to oxygen the ear th 's mo st common element - - l ong has been known by scientists to pos s es s s upe rior temp erature s tab i lity and power handling characteristics.

But up until now , the difficulties of

purifying, "growing'' a single crystal, and f a br icating s ilic on trans istor s have kept them laboratory devices , unreproducib l e on a production- line

The manufacture of a transistor i s a marvel of m o d e rn sci enc e , with laboratory techniques put on a production-line basis.

The semic onducto r

material first must be purified to the purest substance kno wn t o man . . . with less than one part impurity in on e billi o n!

Page 4 new transistor

Then a single large perfect crystal must be "grown" at high temperatur e in an inert atmosphere with a ''seed" crystal continually being rotated and "pulled" from the molten purified semiconduc tor material. And as if that were not difficult enough, the electrical characteris tics of the crystal must be changed during "growing" so that the single crystal will have portions with dissimilar current-ca rrying characteris tics. Two months ago, Texas Instrument s began production of a simple single crystal silicon semicondu ctor device -- a silicon alloyed junction diode use for signal rectificatio n -- experience with which led to placing the silicon triode transistor into production.

The new silicon transistors

are already in small, but growing volume production and units are immediately available on a limited quantity basis to insure widest possible distri­ bution.

SILICON TRANSISTOR BULLETINS

Descriptive literature on the first commercially available silicon transistors is announced by Texas Instruments Incorporated.

Bul-

letins are available on both the Types 900 and 901 general purpose silicon transistors and the X-15 medium power silicon transistor. The silicon transistors offer higher power outputs and more independence from ambient temperatures than their germanium counterparts.

The silicon transistors will operate up to l 50°C, with

current amplification factor (Alpha) being essentially independent of temperature change"

The X-15 is conservatively rated at 1 watt

power dissipation. All three production types of silicon transistors are n-p-n grown junction units manufactured with glass-to-metal hermetic sealing.
