H01L29/80 - CPC Classification

Classification description:

Semiconductor devices adapted for rectifying, amplifying, oscillating or switching, or capacitors or resistors with at least one potential-jump barrier or surface barrier, e.g. PN junction depletion layer or carrier concentration layer; Details of semiconductor bodies or of electrodes thereof; Multistep manufacturing processes therefor; Types of semiconductor device ; Multistep manufacturing processes therefor controllable by only the electric current supplied, or only the electric potential applied, to an electrode which does not carry the current to be rectified, amplified or switched; Unipolar devices, e.g. field effect transistors; Field effect transistors with field effect produced by a PN or other rectifying junction gate, i.e. potential-jump barrier
