Class Information
Number: 257/E29.073
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Semiconductors devices adapted for rectifying, amplifying, oscillating, or switching, capacitors, or resistors with at least one potential-jump barrier or surface barrier (epo) > Electrical characteristics due to properties of entire semiconductor body rather than just surface region (epo) > Characterized by materials of semiconductor body (epo) > Structures with periodic or quasi-periodic potential variation, (e.g., multiple quantum wells, superlattices) (epo) > Doping structures (e.g., doping superlattices, nipi-superlattices) (epo)
Description: This subclass is indented under subclass E29.072. This subclass is substantially the same in scope as ECLA classification H01L29/15C.
