A cover that is resistive to the etch defines the layout. Once the cover is in position, the exposed material may be etched using either "wet (chemical)" or "dry (physical)" processes. Traditionally, ...

An example of directional etching for nanohole arrays of less than 500nm in diameter. (Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types ...

Beautiful spiral patterns had been etched into the germanium surface by a chemical reaction ... re-incubated the chip with the same etching solution in a wet chamber to prevent evaporation.

Further experiments showed that the patterns arise from chemical reactions that are ... and re-incubated the chip with the same etching solution in a wet chamber to prevent evaporation.

Illinois is using is metal-assisted chemical etching (‘MacEtch’), in which a metal ... results as ‘Ultra-high aspect ratio InP junctionless finfets by a novel wet etching method‘ in Electron Device ...

Researchers in Germany and France have now developed a new wet-etch technique to make micron-sized (Cd,Hg)Te/HgTe structures that does not damage the samples and leaves the crystalline structure of ...
