This work provides a treatment of BiCMOS technology from several perspectives. The manner in which the modern BiCMOS process evolved from a predominantly CMOS processing base is discussed, and a survey of special processing technologies is given. Without these advanced techniques the current level of BiCMOS and CMOS process performance would be unattainable. Examples of such include trench isolation, lightly doped drain structures, and advanced metallization techniques. Additionally, BATMOS, Northern Telecom's BiCMOS process technology is described in detail. Issues pertaining to BiCMOS process scalability, device scalability, and process tradeoffs are discussed. Included are such topics as active device scaling, second order effects which become important in scaled technologies, BiCMOS process tradeoffs, and latchup in BiCMOS. Several high performance arithmetic architectures were implemented in the form of macrocells, and their design is discussed. Toward that end, a survey of hardware multipliers is given, concentrating on the parallel types, and two new recently proposed architectures are described which form the basis for five of the six macrocells. As well, the implementation of a fast adder macrocell is treated. Some details of the design process of these macrocells are also highlighted. The use of BiCMOS in the realization of dynamic, massively pipelined arithmetic structures is explored. A review of pipelining strategies is briefly given, followed by a description of the true single phase clocking (TSPC) technique. Factors effecting the implementation of NMOS transistor switching trees in BATMOS is investigated, and key simulation results are reported. A new latching principle is described which is based on a current steering concept. (Abstract shortened by UMI.)Dept. of Electrical and Computer Engineering.
