Latest Patents

Thomas E. Pierson holds a patent for a "Method of forming smooth morphologies in InP-based semiconductors." This invention describes a semiconductor dry etching process that provides deep, smooth (RMS of less than approximately 5 nm), and vertical etching of InP-based materials using Inductively Coupled Plasma Reactive Ion Etching (ICP RIE) with a chlorinated plasma and the addition of hydrogen gas. The process also allows for the inclusion of inert gases such as nitrogen and argon. The invention aims to produce relatively high anisotropy with exceptionally smooth surfaces, requiring the amount of hydrogen gas added to exceed the volumetric measure of chlorinated gas at a ratio greater than 1:1. This improved dry etching process yields deep, vertical etch profiles with enhanced surface smoothness and high manufacturing etch rates.
