Etching is a method employed during the fabrication of semiconductors to chemically remove layers from the surface of the wafer substrate. Etching is a crucial process, and each wafer is subject to ...

With photolithography not able to produce circuit lines much thinner than 100nm, a major focus of research into nanotechnology is in developing means to construct circuits that break the 100nm barrier ...

[Sebastian] probably didn’t think he was wading into controversial waters when he posted on his experimental method for etching PCBs (in German). It’s not like etching with hydrochloric acid and ...

Silicon nitride etch has been one of the foundations of semiconductor manufacturing for a number of years. Overall silicon (Si) etch rate is dictated by the combination of process temperature and H 2 ...

A team of physicists has uncovered some of the physics that make possible the etching of silicon computer chips, which power cell phones, computers, and a huge range of electronic devices. Physicist ...
