Patent number: 4152715Abstract: CCDs and bipolar transistors are formed together on a silicon chip. For n channel CCDs and npn transistors, only a single extra diffusion is necessary in addition to the diffusions used for the CCDs alone. This step is diffusion of n.sup.+ collector wells, and is performed before CCD channel stop-transistor base diffusion. For p channel CCDs and pnp transistors, two extra diffusions are necessary and are: diffusion of a p collector wells, and diffusion of n.sup.+ base contracts; the extra diffusions may both be performed before CCD channel stop-transistor base diffusion, or the n.sup.+ base contact diffusion may be performed thereafter.Type: GrantFiled: November 28, 1977Date of Patent: May 1, 1979Assignee: The United States of America as represented by the Secretary of the ArmyInventor: Chi-Shin Wang
