(under subclass 615) Subject matter in which one of the components is described as being an electrical semiconductor, that is, a material with an electrical conductivity between that of a conductor and an insulator.
(1) Note. Claimed recitation of electrical conductor means or electrical components, even nominally, will result in the subject matter being classified elsewhere, e.g., in Classes 174, 257 or 361, appropriate subclasses.

641, for a composite having a silicon- or germanium-base component which is not described as a semiconductive component.

148, Metal Treatment,
33+, for electrically semiconductive stock under the Class 148 definition which is essentially homogeneous and has at least two contiguous layers differing in the number of unbound electrons and/or differing in energy gap levels, which exhibit a junction between the layers.
174, Electricity: Conductors and Insulators,
102+, for armor or sheath devices of that class which may be semiconductive.
252, Compositions,
62.3, for barrier layer compositions, and subclasses 500+ for other semiconductor compositions.
257, Active Solid-State Devices (e.g., Transistors, Solid-State Diodes), appropriate subclasses for such devices, wherein the solid state material is typically a semiconductor.
