  • Reactive Ion Etching Tool and Wafer Etching | Cleanroom

    IntroductionOverviewWafer Etching with The Rie Tool1.1 Purpose This document describes the procedure for etching wafers with the RIE machine. 1.2 Scope This document describes an etching process using the RIE (Reactive Ion Etch) tool. The RIE tool is set up to etch either silicon using CF4/8% O2 or photo resist (including e-beam resist) using O2. This document is limited to the process of etching into silicon and an evaluation of the etch rate and the resist ablation. 1.3 Definitions Etch: A trench in a semiconductor substrate that may be formed either by an isotropic or an anisotropic means. Resist: A chemical that inhibits etching. Ablation: The physical eroding of resist on a wafer sample during the reactive-ion etching process. In this particular case, the ablation also includes some chemical etching of the resist from the included Oxygen in the reaction gas. Isotropic Etch: A nondirectional etch that results in undercutting of the resist mask. Anisotropic Etch: A directional etch. In our case, we want a trench with vertical wal...
