DEFINITION

Classification: 257/351

Complementary field effect transistor structures only (i.e., not including bipolar transistors, resistors, or other components):

(under subclass 350) Subject matter wherein the field effect transistor and the diverse type device are field effect transistors which are complementary in conductivity type to each other (e.g., provide a CMOS structure).
