WebDry photoresist ashing, stripping, and descum use oxygen plasma to generate radical oxygen species to chemically remove the photoresist layer on the silicon wafer. The byproducts of oxygen plasma ashing are not toxic. It’s more environmentally friendly than the wet etching process. Energetic electrons inside the plasma can break down oxygen ...

WebJonas Sundqvist received his PhD in inorganic chemistry from Uppsala University, Department for Materials Chemistry at The Ångström Laboratory in 2003 where he developed ALD and CVD processes for metal oxide ALD and CVD processes using metal iodides. In 2003 he joined Infineon Memory Development Centre (MDC) as a process … Web1.1.2 Etching Etching is used to remove material selectively in order to create patterns. The pattern is defined by the etching mask, because the parts of the material, which should remain, are protected by the mask. The unmasked material can be removed either by wet (chemical) or dry (physical) etching. red meat cholesterol myth
