    摘要: A complementary field effect transistor structure which eliminates the problems caused by parasitic currents between devices. The currents are contained within parasitic bipolar devices formed between the various regions of the FETs. A portion of the collector current of the parasitic bipolar devices is drained away so that the loop gain is less than one. This is achieved by placing guard regions of conductivity type which are the same as the channel type of the transistors adjacent said regions. The guard region is preferably in the form of a continuous ring around its associated FET.
