Title: Peter D. Doenges and Wafer Container Innovation.

Introduction

Peter D. Doenges is an inventor associated with Chaska, Minnesota, and Entegris, Inc. His patent work addresses the distribution of purge gas inside wafer containers used to protect and handle semiconductor wafers.

Latest Patents

The provided information identifies one patent for Doenges: “Wafer Container and Purge System.” The invention positions diffusers closer to the container’s center line to improve purge-gas distribution. The diffusers may align with a recessed central panel on the back wall, and their relative angle around the wafer’s center may be 60 degrees or less. Offset connectors can place the diffusers closer to the center line than the purge ports, with the distance from each diffuser to the center line less than one quarter of the accommodated wafer’s diameter. Doenges is credited with 1 patent.

Career Highlights

Doenges’s listed work connects him with Entegris, Inc., a company serving the semiconductor industry. His patent focuses on wafer-container design and purge-system performance, with diffuser placement intended to improve gas distribution.
