Continuous Film Transistor Fabrication Process

US Patent:
39508439, Apr 20, 1976
Sep 15, 1971
Appl. No.:
Arthur E. Horton - Richardson TX
Jordan W. Brantley - Hurst TX
Paul R. Smith - Dallas TX
Cecil W. Lightfoot - Dallas TX
Richard L. Hanneman - Dallas TX
Texas Instruments Incorporated - Dallas TX
International Classification:
B01J 1700
US Classification:
A continuous film transistor fabrication process utilizes a roll of polyimide substrate film on which a plurality of groups of three metal contacts is patterned. The edges of the film are turned under, including portions of the metal contacts, to facilitate the ohmic bonding of the substrate contacts to other respective contacts on a support member. Holes are formed in the film between each pattern to act as indexing means for feeding the film through a series of processing stations. As the film passes through each station, a separate step in the fabrication takes place, until the completed, tested, and sorted transistors are removed from the last station.
