DEVELOPMENT OF TECHNIQUES FOR AUTOMATIC MANUFACTURE OF INTEGRAL CIRCUITS. VOLUME II - APPLICATIONS MANUAL FOR COMPUTER-AIDED DESIGN OF INTEGRAL CIRCUITS.

Abstract : The time and cost required for development of integral circuits can be greatly reduced by applying modern techniques of computer-aided design. In the planned man/machine system, the designer will rapidly construct mask layouts by interacting with a high-speed digital computer via a cathode-ray tube display. The present prototype system simulates this action through plotted displays and a symbolic language. The design language uses a problem-oriented vocabulary of commands (MOVE, BEND, MOAT, etc.) in an easily learned English-like syntax. A set of symbolic expressions enables the designer to place components precisely without concerning himself with actual dimensions and tolerances. The computer automatically obeys built-in rules to insure consistency with the selected fabrication processes. Operation of the prototype system was tested by the analysis and layout of a new type of microelectronic IF amplifier. The circuit was then manufactured in a single fabrication run, and exhibited excellent performance. Included herein are detailed instructions for the solid state device designer for use of the prototype system. Details of the design philosophy of the prototype system and results of related studies are presented in Volume I. (Author)
