Class 438: Semiconductor Device Manufacturing: Process
This class provides for manufacturing a semiconductor containing a solid-state device for the following purposes: (a) conducting or modifying an electrical current, (b) storing electrical energy for subsequent discharge within a microelectronic integrated circuit, or (c) converting electromagnetic wave energy to electrical energy or electrical energy to electromagnetic energy. Also operations involving: (1) coating a substrate with a semiconductive material, or (2) coating a semiconductive substrate or substrate containing a semiconductive region. It also provides for operations involving etching a semiconductive substrate or etching a substrate containing a semiconductive region. The class provides for packaging or treatment of packaged semiconductor.Subclass 164: Semiconductor islands formed upon insulating substrate or layer (e.g., mesa formation, etc.)
Subclass 474: Ionized radiation (e.g., corpuscular or plasma treatment, etc.)
Subclass 513: Plasma (e.g., glow discharge, etc.)
Subclass 691: Combined mechanical and chemical material removal
Subclass 795: RADIATION OR ENERGY TREATMENT MODIFYING PROPERTIES OF SEMICONDUCTOR REGION OF SUBSTRATE (E.G., THERMAL, CORPUSCULAR, ELECTROMAGNETIC, ETC.)
Subclass 798: Ionized irradiation (e.g., corpuscular or plasma treatment, etc.)
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 E21.411: Thin film unipolar transistor (EPO)
