Transistor Automated Tape Assembly Display - SATAN was a TI project of 1970-72 that produced an automated assembly on tape of germanium transistors designed for thick film hybrid circuit applications.

SATAN was an acronym for Semiconductor Automated Tape Assembly with the "N" added to become SATAN. The construction is described in bulletins and data sheets in the Artifact Historical Files. The assembly was not fully automatic. Positioning for chip mounting, wire bonding and epoxy application was operator controlled with the use of TV monitors. The operation was activated by an operator controlled switch. The equipment was designed and built in the TI Deutschland plant. SATAN devices were especially designed to provide the thick film hybrid user with the ability to fabricate systems using a single mounting technique for all components. Also, these devices could be mounted in a TO-18 package if desired, as shown in the display. Production rates reached approximately 50k units per month for over a year. The principal customer was RCA Indianapolis for the XL100 color television audio circuit. Small quantities were used by others, such as Zenith. The limited hybrid thick film applications resulted in cancellation of the project.

Integrated Circuit Display, Master Wafer - This item is one of the displays used in the mid 1960's to promote the Master Slice concept developed by TI. In addition to briefly describing the concept, key production steps are illustrated.

The display has the original title of SOLID CIRCUIT Semiconductor Networks under which TI introduced integrated circuits. The master slice idea was to provide a means of producing a new custom IC with a minimum of design time. For this slice design, 31 components were diffused into each bar (chip) such that a lead pattern mask was the only difference between several standard and custom circuits. Diffused slices could be the inefficient use of bar space caused the idea to be dropped in favor of efficient individual designs.

Transistor Packages Display - This display in plastic show some of the very early transistor packages used or considered for use by TI. From memory and the packages shown, this display was probably made in the latter part of 1953.

No. 1 is the package used for the first TI produced transistor. This was the package used by Bell Labs/Western Electric at the time of the licensing agreement. Nos. 2 - 4 are packages for the first TI designed transistors, germanium point contacts. Nos. 5 - 7 are packages of the designs being used in Engineering at the time for evaluation. At that time, the industry was in the process of developing a standard small signal transistor package. The package finally selected by TI was dimensionally very close to No. 7. The header had a kovar rim and leads sealed in glass. After fabrication of the transistor, the header was solder sealed to a metal can. The 1-53 on the front of No. 2 and the back of No. 3 indicate they were made in January, 1953.

Rectifier Display, Automotive Alternator - This display was made about 1956-7 to illustrate possible packaging and mounting for semiconductor rectifiers to be used for automotive alternators. These systems were just being introduced in that time period.

The aluminum plate illustrated how a rectifier could be rolled into the plate. Six units would be mounted on a plate in this manner, and the plate would be mounted on the alternator to provide heat dissipation along with the electrical connection. The copper base plastic unit could be rolled into the plate or solder mounted. The black devices provided a stud mount with a steel cap roll sealed into the top of the package. The gold plated unit used a glass-to-metal seal cap welded to the stud mounted header(base). In 1985-6, this display appears somewhat tentative. But, in 1956-7, the semiconductor industry was just begging to gain knowledge and experience with high current rectifiers, glass-to-metal seals and plastic encapsulation.

It was used in the first TI watch modules (1975) which were sold to Benrus but were not used by TI for watches. The X-902, also I2L, was the next design and was widely used in TI watches, which were introduced in late 1975. It was probably the largest volume chip used. The IC and module design and manufacturing technology not only made possible an electronic watch but provided the means for cost reductions and an accurate very low cost watch.

G00004   NMAH Catalog Number 1987.0487.368
 
TI number: G00004
Transistor, Ladder Assembly Display - This technique was an early (1954) effort to improve production by small batch fabrication.

Was part of the original South Building lobby display. Multiple germanium bars were fused to platinum strips with Au-Ge die, and platinum wire was fused to bar junctions with dots in a single furnace operation. Bar units were cut apart and mounted on a header by welding. This process provided improved productivity at the time and was used at TI from 1954 to 1956. The item is mounted on a display panel and has a separate display drawing of the assembly.

G00030   NMAH Catalog Number 1987.0487.429
 
TI number: G00030
Photo Available Header Fabrication Display - Displays step by step fabrication of the first 1/4in x 1/8in IC flatpack header design.

The final seal for this package was made by solder sealed kovar lid. The ceramic base, ring frame and lead frame were sealed together with glass frit. This design was used in the 1959-62 time period.

G00031   NMAH Catalog Number 1987.0487.430
 
TI number: G00031
Photo Available Header Fabrication Display - Displays step by step fabrication of the second production version of the 1/4" x 1/8" IC flatpack.

The header has a kovar base plate stitch welded to the lead frame. The lead frame was sealed to the ring frame with glass frit. For final seal, a kovar lid was stitch welded to the ring frame. Production in this package was started in early 1963. Although refinements in the design were made from time to time, it remaind the basic flatpack and was used for many special transistor and diode applications as well as IC's.

G00334   NMAH Catalog Number 1987.0487.431
 
TI number: G00334
Photo Available Integrated Circuit Fabrication Display - Displays step by step process of the fabrication of an integrated circuit (initially called Semiconductor Network at TI). The display probably was made in 1962 or early 1963 and represents production of that period.

This item is the same G00027 & 148 except for part details. The estimated date for the display is based on the 7/8" slice diameter, mask size, package construction and painted device.
