Design of a package for a high-speed processor made with yield-limited technology

Abstract

The design of an advanced high density thin film multichip module (MCM) for a 1-ns cycle time Fast Reduced Instruction Set Computer (F-RISC/G) is described. The processor has been implemented with GaAs/AlGaAs heterojunction bipolar transistor (HBT) technology from Rockwell International. The F-RISC/G package pushes the state of the art to satisfy electrical, thermal and thermomechanical constraints to take advantage of this high speed circuit technology. A unique approach is developed to link the electrical and thermomechanical design environments using a common database.<>
