Simulation of Anisotropic Chemical Etching of Single Crystalline Silicon using Cellular-Automata

Abstract

However, the etch process is depends on the crystal orientation, etching temperature, etchant concentration, and the length of time the wafer re-mains in the etchant 1. The final structure determined by Si anisotropic etching is difficult to predict precisely. Etch3DTM simulator addresses this challenge by wet etch-ing simulation 2.

Anisotropic Crystalline Etch Simulations

We propose a new concept for anisotropic single crystalline silicon (Si) etching simulation. Our approach combines three calculation modules, a molecular dynamics calculation module to define chemical reaction probability, a Cellular-Automaton module to calculate etching rate, and a Wulff-Jaccodine graphical method module to predict an etched shape. This configuration allows mm scale process simulation based on atomic scale physical chemistry of anisotropic Si etching. In this paper, the performance of a newly developed Cellular-Automata module, called CAES (Cellular-Automata Etching simulator), is presented as a first step towards the realization of our simulation concept.

• We have developed an anisotropic-chemical-etching process simulation system, MICRO-CAD, which is equipped with a database of orientation dependent etching rates of single crystal silicon. When crystallographic orientation of the wafer, mask pattern, etching media and etching conditions such as its concentration and temperature are given, it calculates 3D etching profiles according to the.
