A Diffusion Link Laser Programmable Read Only Memory and Automated Programming Station
Abstract
Laser programmable read only memory circuits expand the applications of VLSI circuits. This thesis considers a laser programmable diffusion link as vehicle for implementing a high speed static memory circuit. this thesis involves designing a laser programmable ROM and designing, assembling, and demonstrating an automated laser programming station. This system includes a laser and optics, a stepper motor controlled X-Y translation stage, and a camera with pattern recognition firmware. The capabilities and limitations of this automated system are examined. The layout of the LPROM circuit illustrates design considerations for integrating a laser programmable diffusion link into a VLSI circuit. The required accuracy of the programming station is obtained at the expense of the time necessary to execute the pattern recognition firmware. Keywords: System engineering, Fabrication.
