Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)
This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.Subclass 262: Combined with insulated gate field effect transistor (IGFET)
Subclass 288: Having insulated electrode (e.g., MOSFET, MOS diode)
Subclass 377: With polysilicon interconnections to source or drain regions (e.g., polysilicon laminated with silicide)
Subclass 382: With contact to source or drain region of refractory material (e.g., polysilicon, tungsten, or silicide)
Subclass E21.019: Made by depositing layers, e.g., alternatingly conductive and insulating layers (EPO)
