Introduction

A Grey Lerner is a notable inventor based in Portland, Oregon, with a significant contribution to the field of silicon etching technology. With two patents under his name, Lerner has developed innovative methods and systems that enhance the precision and efficiency of silicon processing.

Latest Patents

Lerner’s latest patents include a novel method and system for silicon etching control. This system is designed to regulate the exposure of a silicon workpiece to a spontaneous etchant. It accurately calculates the amount of material to be removed based on metrology information related to the silicon workpiece. Furthermore, the system estimates the etch time needed, monitoring the change in mass of the workpiece to determine when the desired amount of material has been removed. The process is halted when the measurements indicate the completion of etching.

Another innovative patent by Lerner addresses optical component cleanliness in laser micromachining applications. This invention comprises preferred embodiments of a purge gas port, laser beam attenuating input window, and a laser shutter. The system optimally injects purge gas through multiple locations within a beam tube assembly, thus preserving the integrity of optical components by minimizing contamination. The input window is designed as a fixed level attenuator to restrict photopolymerization of airborne particles, and the use of periodically rotating optical elements helps reduce burn damage to the optics.
