Metal-catalyzed silicon etching is one of the commonly used methods. The purpose of this paper is to study the morphology and mechanism of metal-catalyzed silicon etching in different etching solutions.This study will be carried out from the following aspects: (1) introduce the basic principles of silicon etching and the mechanism of metal-catalyzed silicon etching; (2) introduce different etching solutions, including different metal ions, acidity and alkalinity, and analyze their effects on the morphology of silicon etching; (3) study the morphology characteristics of silicon etching under different etching conditions through SEM and TEM, compare the similarities and differences under different systems; (4) explore the change of the mechanism of metal-catalyzed silicon etching, including the reaction path between metal ions and silicon and other factors.It is expected that this study can deepen the understanding of the morphology and mechanism of metal-精品文档---下载后可任意编辑catalyzed silicon etching under different etching conditions, and provide references for the optimization of semiconductor fabrication processes.Keywords: silicon etching; metal-catalyzed; morphology and mechanism study; semiconductor fabrication.
