Strictly speaking, a semiconductor is a material with an electrical conductivity between that of an insulator and that of a conductor. Semiconductors can be single elements such as silicon or germanium or compounds such as gallium arsenide or indium phosphide. In day to day usage, however, the term "semiconductor" more frequently refers to the components manufactured from semiconductor materials.
