Class Information
Number: 257/492
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > With means to increase breakdown voltage threshold > In integrated circuit > With electric field controlling semiconductor layer having a low enough doping level in relationship to its thickness to be fully depleted prior to avalanche breakdown (e.g., resurf devices)
Description: Subject matter wherein the means to increase breakdown voltage of the device includes a layer of semiconductor material having a sufficiently low doping concentration that it may be fully depleted by the depletion region of a reverse biased junction of the active device prior to avalanche breakdown of the active device, so that upon depletion of the layer of semiconductor material, the effective width of the depletion layer of the reverse biased junction of the active device is greatly expanded, thus resulting in smaller increases in electric field intensity with further increases of reverse voltage.
