Title: The Innovative Contributions of Marion I Simmons
Introduction
Marion I Simmons is a notable inventor based in Tempe, Arizona, recognized for her significant contributions to the field of semiconductor technology. With a total of four patents to her name, Simmons has made strides in improving the efficiency and reliability of semiconductor devices. Her work has been instrumental in advancing the capabilities of electronic components used in various applications.
Latest Patents
One of Simmons' latest patents is for a low resistance probe for semiconductors. This innovative probe is designed to form a low resistance electrical connection to a semiconductor die. It features a contact that is created on a compliant layer supported by a substrate. When pressure is applied to the contact, the compliant layer compresses, allowing the contact to move in an arc motion. This movement scrubs across the bonding pad of a semiconductor die, breaking through the oxide layer that typically forms on the pad, thus establishing a low resistance electrical connection.
Another significant patent by Simmons is a method for plating tab leads in an assembled semiconductor package. This method enhances the bonding characteristics of TAB semiconductor packages to circuit boards by plating additional amounts of tin on the leads after the final package assembly. The residues from the plating process are carefully removed to prevent contamination, and any stresses developed during plating are alleviated by heating the leads.
