FIELD EFFECT TRANSISTORS AND METHODS FOR MAKING FIELD EFFECT TRANSISTORS |
摘要 |
The insulative gate layer of an insulated gate field effect transistor (IGFET) is made by exposing a channel region of a semiconductor wafer to high energy proton bombardment. The bombardment damages the crystal structure of the semiconductor to a predetermined depth to make that part of the semiconductor nonconductive.
