(under the class definition) Subject matter comprising a semiconductor compound that includes an organic material 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. Certain compounds are exceptions to this rule, i.e., HCN, CN-CN, HNCO, HNCS, cyanogen halides, cyanamide, fulminic acid, and metal carbides. These are not regarded as
organic materials.
(2) Note. Graphite and diamond are not regarded as organic, since they are not compounds; silicon carbide is not regarded as organic. Active solid-state devices using silicon carbide or diamond as the semiconductor are in subclass 77 of this class.
(3) Note. Organic insulating materials, as opposed to semiconducting materials, do not go in this subclass.
