Abstract : This report describes the progress achieved during a three-year program to develop deposited dielectrics for GaAs device applications. Three applications of dielectrics have been investigated within this program: (1) isolation of control electrodes, (2) passivation of the GaAs surface, and (3) encapsulation of completed circuits. Deposition techniques employed were plasma-enhanced deposition (PED), pyrolytic chemical vapor deposition (CVD), and photo-chemical deposition (PCD). Plasma-enhanced dielectrics suitable for applications (1) and (3) were developed under Hughes internal funding early in the course of the program. Accordingly, the program was streamlined to concentrate on application (2).
