Class Information
Number: 257/E29.001
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)
Description: This main group provides for semiconductor devices which operate by the movement of charge carriers, i.e. electrons and holes, from one energy level to another within the semiconductor material and can modify an input voltage to achieve rectification, amplification, oscillation or switching action, or capacitors or resistors with at least one potential-jump barrier or surface barrier. This subclass is substantially the same in scope as ECLA classification H01L29/00.
