Title: Innovations by Inventor John Clark
Introduction
John Clark is a prominent inventor based in Philadelphia, PA, known for his significant contributions to the field of semiconductor processing. With a total of seven patents to his name, he has made remarkable advancements in wafer thinning and etching technologies.
Latest Patents
Among his latest patents is the "Two etch method for achieving a wafer thickness profile." This innovative system and method facilitate a wet etching process that includes multiple processing stations accessible by a transfer device. The system features a measuring station that optically measures the thickness of a wafer before and after each etching step. A controller analyzes these thickness measurements against a target wafer profile, generating dynamic etch recipes in real time for each step. Additionally, the process controller can direct a single wafer wet etching station to etch the wafer according to the generated recipes, refining them based on pre and post-etch measurements.
Another notable patent is the "Apparatus and method for wafer thinning in advanced packaging applications." This system employs a two-step wet etching process for semiconductor wafers, where the first etch step uses a non-selective etchant for the wafer material and metals present. The second etch step utilizes an etchant that is selective to the wafer material, ensuring that the metals remain substantially intact.
