Introduction

Arthur R Elsea, Jr. is a notable inventor based in Fremont, CA (US). He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His innovative methods have advanced the processes involved in creating integrated circuits.

Latest Patents

One of his latest patents is titled "Method of making laser generated I.C. pattern for masking." This patent describes an improved method of patterning layers on a semiconductor element using laser processing. In this method, a thin film of amorphous silicon is deposited on a fused quartz window. Selected regions of the amorphous silicon are crystallized by a laser beam focused through the quartz window. The non-crystallized silicon is then removed, forming an opaque layer of crystallized silicon in the desired pattern. The quartz window serves as a window to a reactive gas containment chamber containing semiconductor devices to be patterned. By irradiating the chamber with ultraviolet light through the patterned quartz window, the semiconductor element is etched in the regions exposed to the light.

Another significant patent is the "Method for fabricating laser generated I.C. masks." This patent outlines an improved method of making masks that involves forming a layer of amorphous silicon of about 2,000 angstroms on a transparent substrate. A laser beam is directed through the transparent substrate, traversing the amorphous silicon to create a pattern of crystallized silicon. The non-crystallized silicon is then etched away, leaving a patterned substrate that is used as a mask for exposing photoresist on semiconductor elements.
