METHODS FOR ETCHING SUBSTRATE AND SEMICONDUCTOR DEVICES |
摘要 |
A method of etching a substrate using a metal-assisted chemical etching process is provided. The method may include forming a metal catalytic layer to a predetermined thickness on a substrate and reacting the metal catalytic layer with the etching solution to form a porous surface in the metal catalytic layer and etch the substrate. When the metal catalytic layer is reacted with an etching solution, a porous surface may be formed on the metal catalytic layer. |
