Title: Innovations of Wen Teh Chang
Introduction
Wen Teh Chang is a notable inventor based in Sunnyvale, CA, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in plasma reactor technology, which has significant implications in various industrial applications.
Latest Patents
Chang's latest patents include a method of matching two or more plasma reactors. This innovative approach captures etch rate distributions at various hardware tilt angles of the RF source power applicator relative to the workpiece. The non-uniformities are computed, and the behavior is modeled as a non-uniformity function for each plasma reactor. An offset in tilt angle between the non-uniformity functions of the reactors is detected, allowing for precise matching by adjusting the tilt in one of the reactors. Another significant patent is a predictive method of matching two plasma reactors, which similarly predicts etch rate distribution non-uniformities and models the behavior for effective reactor matching.
