The manufacturing process flow has been designed to allow all standard CMOS steps to occur at the front end of the process, with the micromachining steps performed after the circuitry is completed.

—The development of a process flow capable of demonstrating functionality of a monolithic complementary FET (CFET) transistor architecture is complex due to the need to vertically separate nMOS and ...
