(under the class definition) Subject matter in which the active device is made up of a semiconductor material whose electrical characteristics are due to the electronic properties of the semiconductor material, which are exhibited throughout the entire body of material rather than in just a localized region thereof (e.g., the surface).
(1) Note. Excluded from this subclass are semiconductive devices whose nonlinear characteristic is due to a junction rather than to the bulk properties of the semiconductor, whether they are homojunctions (i.e., made up of the same semiconductor material with different dopant ions on opposite sides of a junction) or heterojunctions (i.e., made up of different materials on either side of a junction).
