Introduction

Jeffrey T. Koze is a notable inventor based in Whitehall, PA, with a focus on advancements in semiconductor technology. He holds three patents that reflect his contributions to the field of integrated circuits and semiconductor processing.

Latest Patents

One of his latest patents is titled "Integrated circuits from wafers having improved flatness." This invention enhances silicon wafer flatness by reducing the time spent in polishing the wafer. After a conventional lapping operation, the wafer is coated with an etch-resistant material, typically silicon nitride. A polishing step removes the nitride coating on the flat surfaces while leaving it on the sides of pits formed during lapping. The wafer is then etched to remove the silicon surface below the depth of the pits, resulting in improved flatness for lithography techniques used in integrated circuit formation. Another significant patent is "Back sealing of silicon wafers." This technique prevents the evaporation of dopants during the growth of an epitaxial layer on the front side of the wafer. By depositing an oxide layer during the furnace ramp-up, it avoids extra processing steps and reduces the temperatures required, leading to a greater yield of usable wafers.
