Class Information
Number: 257/212
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Conductivity modulation device (e.g., unijunction transistor, double-base diode, conductivity-modulated transistor)
Description: Subject matter wherein the active solid-state device has a high resistivity semiconductor region of one conductivity type having a region of opposite conductivity type forming a pn junction with a central portion of the high resistivity layer, with structural means provided to forward bias the pn junction to inject minority carriers into the high resistivity region to increase its conductivity through conductivity modulation.
