Title: Kevin G Rhoads: Innovator in Electrical Contact Systems and Coating Characterization

Introduction

Kevin G Rhoads is a notable inventor based in Andover, MA (US), recognized for his contributions to electrical contact systems and coating characterization. He holds a total of four patents, showcasing his innovative approach to solving complex engineering challenges.

Latest Patents

One of Rhoads' latest patents is an "Active method and system of establishing electrical contact." This invention involves a system designed for electrically contacting a semiconductor wafer during the implantation process. The system includes pairs of closely spaced contacts adjacent to the wafer, connected to a driving circuit that facilitates a discharge between the contacts and the wafer. The design allows for sharp points on the contact tips to aid in establishing corona at lower drive voltages, or alternatively, rounded contacts that may directly contact the wafer. The driving circuit can be adapted from various discharge circuits, including pulsed and continuous discharge circuits.

Another significant patent is the "Method for characterizing coating and substrates." This system characterizes coatings and substrates of a material under test by positioning a sensor against a coated sample to obtain phase and magnitude measurements. The penetration depth of the magnetic waves from the sensor varies with frequency, allowing for accurate determination of the conductivities of the coating and substrate. Through iterative approximations, the coating thickness and lift-off can also be accurately measured.
