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 ...

Extracting hydrogen from water through electrolysis offers a promising route for increasing the production of hydrogen, a clean and environmentally friendly fuel. But one major challenge of water ...

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 ...

RENA Technologies, a German supplier of wet chemical processing equipment for the solar industry, has teamed with the Christian Albrecht University in Kiel (CAU) to develop a new manufacturing process ...

If you were building a recreation of the James Watt micrometer, where would you start? If you’re [rasp], the answer would be: “Spend a year trying to find the best way to make etched brass discs.” ...

[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 ...
