Title: Gunars M Ozols: Innovator in Etching Technology
Introduction
Gunars M Ozols is a notable inventor based in Wappingers Falls, NY (US). He has made significant contributions to the field of etching technology, holding a total of 4 patents. His work primarily focuses on improving the efficiency and effectiveness of etching processes.
Latest Patents
One of his latest patents is for a cathode designed for reactive ion etching. This innovative cathode enhances the etch rate and uniformity of etching on various objects. It features a quartz plate with a series of recesses containing disks made from the same material as the object being etched, along with a ring of that material around the outer edge of the plate. In a preferred embodiment, the cathode is specifically designed for etching silicon wafers, incorporating silicon disks recessed in a quartz plate at each wafer holding position, complemented by a ring of silicon around the outer edge.
Another significant patent by Ozols involves a method for forming aluminum/copper alloy conductors. This process entails creating a patterned layer of copper on top of a layer of aluminum. The unprotected portion of the aluminum layer is then removed through reactive ion etching, followed by heating the resulting structure to facilitate the diffusion of copper into the aluminum layer, resulting in an alloy.
