Reactive ion etching原理
WebHighly controllable silicon nano-grass formation is reported based on a hydrogen assisted reactive ion etching method in desirable shapes and locations. By controlling the etching parameters, one can achieve grass-free high aspect ratio vertical or three-dimensional structures on silicon substrates. On the other hand, one can program the ... WebThis physical etching style is often termed ‘ion milling’. The second type is Reactive Ion Beam Etching or RIBE where a chemically reactive gas such as SF 6, CHF 3, CF 4, O 2 or Cl 2 (other gases can also be used) is usually added to Ar or other inert gas. There are two ways for introducing the reactive gas: either through the etching
