An optical decoder and monolithic component development

This project report covers two important aspects of the microelectronic field; thin film technology and integrated circuit technology. The sections dealing with thin films are mainly concerned with the properties and implementation of photosensitive materials. The remainder of the report deals with the design and fabrication of monolithic integrated circuits. Diffusion theory is applied to obtain working transistors. Two tasks were assigned as part of the project requirements. The first task, described in Part I, was to fabricate and evaluate a light sensing array for decoding timing data. Part II describes the second task which was to develop process techniques for diffused transistors.
