Abstract
Complementary thin fillm transistors (C-TFT) formed on an insulating substrate, comprising a pair of highly resistive n-type silicon islands, a pair of heavily doped n-type regions formed in one of the islands to form source and drain regions of n-channel TFT, a pair of contacts formed on the surface of the other island and establishing a high potential barrier when the underlying region is of n-type and a low potential barrier when the underlying region is inverted to be of p-type. The process for manufacturing complementary TFTs can be simplified significantly.
