His innovative work focuses on improving the efficiency and effectiveness of processing chambers used in various applications.

Latest Patents

Wong's latest patents include two groundbreaking inventions. The first patent, titled "Frontside and backside pressure monitoring for substrate movement prevention," describes a pressure control system that utilizes a first sensor to detect frontside pressure within a processing chamber. This pressure is indicative of the downforce on a substrate. A second sensor detects backside pressure, and a controller manages the evacuation valve to ensure that the frontside pressure does not drop below the backside pressure. This invention enhances the stability of substrates during processing.

The second patent, "In-situ wafer thickness and gap monitoring using through beam laser sensor," outlines a system for determining the thickness of a substrate in a processing chamber. It employs an emitter to transmit a signal toward the gap between the substrate and a component above it. A receiver captures the transmitted signal, generating a measurement signal that the system controller uses to adjust processing parameters based on the substrate's thickness and the gap width.
