Title: Gerald B Feldewerth: Innovator in Electroplating and Semiconductor Technologies
Introduction
Gerald B Feldewerth is a notable inventor based in Beaverton, OR (US). He has made significant contributions to the fields of electroplating and semiconductor technologies. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
Feldewerth's latest patents include innovative technologies that enhance the performance and reliability of electronic components. One of his patents focuses on an under bump metallization layer that enables the use of high tin content solder bumps. This invention includes an apparatus and methods for fabricating an under bump metallization structure, which consists of an adhesion layer, a molybdenum-containing barrier layer, a wetting layer, and high tin content solder material. The molybdenum-containing barrier layer is crucial as it prevents the movement of tin in the solder material from migrating to dielectric layers, thereby avoiding potential delamination and damage to underlying structures.
Another significant patent is for an anode and anode chamber designed for copper electroplating. This electroplating system features a phosphorized anode with a large average grain size and a plating apparatus that effectively separates the anode from the cathode. This separation is achieved through a microporous chemical transport barrier, which minimizes the transfer of particles generated at the anode to the cathode, thus preventing defects in the electroplated parts.
