Title: The Innovations of Lowell E. Clark

Introduction

Lowell E. Clark is a notable inventor based in Phoenix, AZ, with a remarkable portfolio of 16 patents. His contributions to the field of semiconductor technology have significantly advanced the industry.

Latest Patents

One of his latest patents is the "Backside Processing Method," which is useful in the backside processing of semiconductor wafers. This method involves providing a semiconductor wafer with a processed first surface that is bonded to a handle wafer. Once bonded, backside processing can be performed, and the wafer is sawn while still attached to the handle wafer. This innovative approach reduces handling steps and minimizes the risk of breakage during processing. Another significant patent is the "Balanced Overvoltage Protector for a Dual-Wire System." This invention comprises a single semiconductor substrate with two breakover thyristors positioned closely enough that the current in one thyristor can trigger the other at a voltage lower than its breakover voltage.
