DEFINITION

Classification: 438/780

Depositing organic material (e.g., polymer, etc.):

(under subclass 778) Processes wherein the deposited material is at least partly composed of organic material. An organic compound is one which fulfills the requirements of the Class 260 definitions (i.e., has a molecule characterized by two carbon atoms bonded together, one atom of carbon being bonded to at least one atom of hydrogen or a halogen, or one atom of carbon bonded to at least one atom of nitrogen by a single or double bond, certain compounds such as HCN, CN-CN, HNCO, HNCS, cyanogen halides, cyanamide, fulminic acid and metal carbides, being exceptions to this rule).
