Abstract

A previous article in the IBM Technical Disclosure Bulletin 21, 1668 (September 1978) described a technique for manufacturing a mesa thin film transistor array which involves the deposition of source-drain metallurgy, the deposition of successive layers of semiconductor, insulator, and gate metal, selective etchings to define the devices, sputter passivation, and, finally. the etching of the contact vias.
