Method of making n-channel and p-channel junction field-effect transistors and CMOS transistors using a CMOS or bipolar/CMOS process

摘要

A method of making N-channel and P-channel junction field- effect transistors using a modified CMOS process that simultaneously makes complementary metal-oxide-semiconductor transistors, or a modified BiCMOS process that simultaneously makes bipolar transistors and complementary metal-oxide-semiconductor transistors. Making junction field effect transistors using the basic CMOS process requires mask changes and an additional mask, etch, and implant step. Making junction field effect transistors using the BiCMOS process only requires mask changes.
