Class Information
Number: 257/218
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Field effect device > Charge transfer device > Majority signal carrier (e.g., buried or bulk channel, or peristaltic) > High resistivity channel (e.g., accumulation mode) or surface channel (e.g., transfer of signal charge occurs at the surface of the semiconductor) or minority carriers at input (i.e., surface channel input)
Description: Subject matter wherein the majority signal carrier charge transfer device has a channel made of relatively high electrical resistivity material, or where the transfer of signal charge takes place at the surface of the semiconductor, or where minority charge carriers are input into a surface channel, but majority carriers are input into the bulk or buried channel portion of the device.
