Class Information
Number: 257/E29.167
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) > Types of semiconductor device (epo) > Controllable by plural effects that include variations in magnetic field, mechanical force, or electric current/potential applied to device or one or more electrodes of device (epo)
Description: This subclass is indented under subclass E29.166. Subject matter wherein the performance of the device is regulated by varying the application of two or more forces (i.e., magnetic field, mechanical force, electric current/potential to the device or one or more of its electrodes). This subclass is substantially the same in scope as ECLA classification H01L29/96.
