Title: Innovations by Richard G Christensen

Introduction

Richard G Christensen is a notable inventor based in Wingdale, NY (US). He has made significant contributions to the field of semiconductor manufacturing, holding a total of 5 patents. His work focuses on improving the efficiency and cleanliness of wafer transfer processes, which are critical in the production of high-density semiconductor products.

Latest Patents

One of Christensen's latest patents is the "Wafer transfer apparatus." This invention is designed to support a wafer from below using at least three movable arms, thereby preventing contact with the active surface of the wafer. The apparatus includes a mechanism for moving the arms into and out of the wafer supporting position, which is partially located above the wafer. This design minimizes the risk of contamination from microscopic particles that can fall onto the wafer's active surface. By avoiding sliding contact between elements above the wafer, the invention significantly reduces, if not entirely eliminates, contamination particles produced during the transfer process.

Another significant patent is the "Method and apparatus for making a mask conforming to a ceramic substrate." This invention involves a method and apparatus for creating a mask that conforms to a cured MLC substrate. The mask can be used to add layers of metallization to the substrate through conventional photolithographic techniques. The process features the use of the cured substrate itself to pattern the mask, ensuring precise alignment and image transfer. This innovation also includes methods for improving the MLC substrate by utilizing photolithographic techniques to add successive layers of metallization.
