Title: Innovations by Louis A. Ollivier in Semiconductor Manufacturing

Introduction

Louis A. Ollivier is a prolific inventor based in Palo Alto, California, with a remarkable record of 15 patents to his name. His groundbreaking work primarily focuses on advancements in semiconductor manufacturing, a field of immense significance in today’s technology-driven world. Ollivier has consistently contributed to developing innovative processes that optimize manufacturing efficiency and accuracy.

Latest Patents

One of Ollivier's latest patents revolves around a sophisticated flow control system designed for the batchwise delivery of process gas in semiconductor manufacturing. This system operates in both a flow mode—where gas is delivered in a specified timeframe—and a no-flow mode. Once the delivery begins, the system measures the pressure drop of the gas within a reference capacity. By interrupting the flow from the gas source, it continues to supply process gas to the semiconductor manufacturing apparatus at a carefully controlled flow rate. The measured pressure drop serves as an accurate indicator of the actual flow rate. If discrepancies arise between the actual and specified flow rates, the system autonomously adjusts the controlled flow rate for subsequent delivery cycles. Notably, the components of this innovative flow control system are designed to be compact, forming an elongated delivery stick less than 1.5 inches wide, optimizing space when used for up to 20 units.

Career Highlights

Louis A. Ollivier’s career includes significant roles at prestigious companies, including Veriflo Corporation and Parker-Hannifin Corporation. His work at these organizations has greatly influenced the semiconductor manufacturing sector, allowing for advancements that align with modern technological trends.
