(under subclass 57) Process wherein the semiconductor substrate contains a semiconductive compound in which the molecule is characterized by two or more carbon atoms bonded together, one atom of carbon bonded to at least one atom of hydrogen or halogen (i.e., chlorine, fluorine, bromine, iodine) or one atom of carbon bonded to at least one atom of nitrogen by a single or double bond.
(1) Note. Exceptions to this rule include HCN, CN-CN, HNCO, HNCS, cyanogen halides, cyanamide, fulminic acid, and metal carbides. These are not regarded as organic materials. Also, note that graphite and diamond are not regarded as organic semiconductors, since they are not compounds; silicon carbide is not regarded as organic.
