Title: Frank Ludwig Holsteyns: Innovator in Ultrasonic Cleaning Technologies

Introduction

Frank Ludwig Holsteyns is a notable inventor based in Eksel, Belgium. He has made significant contributions to the field of ultrasonic cleaning technologies, holding 2 patents that showcase his innovative approach to semiconductor wafer treatment.

Latest Patents

Holsteyns' latest patents include an "Ultrasonic cleaning method and apparatus" and a method for treating the surface of a semiconductor wafer. The first patent describes a device and method that provides a treatment fluid in the form of a dispersion of gas bubbles in a treatment liquid. This is generated at acoustic pressures that are less than those required to induce cavitation in the treatment liquid. A resonator supplies ultrasonic or megasonic energy to the treatment fluid, creating an interference pattern that comprises regions of pressure amplitude minima and maxima at the interface of the treatment fluid and the semiconductor wafer. The second patent focuses on a cleaning fluid that includes dispersed gas, avoiding the use of ultrasonic energy to induce cavitation. Instead, it subjects a liquid containing dissolved gas to a pressure reduction in a bubble machine, generating a gas/liquid dispersion. This cleaning fluid can effectively clean articles such as semiconductor wafers using a device that includes a holder and a vibrator for supplying ultrasonic or megasonic energy to the article.
