A disadvantage of wet etching is the undercutting caused by the isotropy of the etch. The purpose of dry etching is to create an anisotropic …
WebReactive Ion Etching (RIE) process uses the ions and radicals for effective photoresist removal. While ions bombard physically to remove photoresist by sputtering, radicals chemically react with the photoresist surface to create volatile molecules such as H 2 O and CO 2. The combination of these two mechanisms is a key of the plasma ashing by ... WebReactive Ion Etching (or RIE) is a simple operation and an economical solution for general plasma etching. A single RF plasma source determines both ion density and energy. Our …
