Class Information
Number: 257/629
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > With means to control surface effects
Description: Subject matter wherein the active junction device has means to modify (e.g., reduce, or eliminate) electrical field effects which take place at the device surface or to modify (e.g., reduce or eliminate) inhomogeneities in electrical properties of a semiconductor crystal region due to effects caused by the discontinuity of the crystal lattice at the surface.
