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 509: Heat treatment
Subclass 93: Compound semiconductor
Subclass 94: Heterojunction
Subclass 95: Chalcogen (i.e., oxygen (O), sulfur (S), selenium (Se), tellurium (Te)) containing
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 442: II-VI compound semiconductor (e.g., HgCdTe)
Subclass E21.463: Using reduction or decomposition of gaseous compound yielding solid condensate, i.e., chemical deposition (EPO)
Class 427: Coating Processes
This is the generic class for: A. applying or obtaining a coating on a surface. The coating may be hard or soft, permanent or transitory, supplied solely by extraneous materials or supplied wholly or in part by the base material. B. impregnating a base by causing a coating material to extend or penetrate into the base material, or into the interstices of a porous, cellular or foraminous material. C. taking preparatory treatments of the base material, subsequent treatments of the coated base material and other ancillary noncoating operations claimed, per se, processes limited to etching for making a base more compatible with, or adherent to, the coating wherein the base is the substrate (work) onto which a coating is applied are included.Subclass 76: Coating is selenium, tellurium, or compound thereof
