Class Information
Number: 257/E29.014
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 specified shape or size of pn junction or by specified impurity concentration gradient within the device (epo) > Characterized by particular design considerations to control electrical field effect within device (epo) > For controlling surface leakage or electric field concentration (epo) > For controlling breakdown voltage of reverse biased devices (epo) > By doping profile or shape or arrangement of the pn junction, or with supplementary regions (e.g., guard ring, ldd, drift region) (epo) > With breakdown supporting region for localizing breakdown or limiting its voltage (epo)
Description: This subclass is indented under subclass E29.012. This subclass is substantially the same in scope as ECLA classification H01L29/06B2B3C.
