Sounds like a win all around. But Twitter wouldn’t stand for this chemical heresy, with comments suggesting that the etching process would release chlorine gas, or that ferric chloride is far ...

[Frankie] and [Bryan] have figured out a way to use the laser to chemically activate an etching process. See experiment part 2 as well. First, to be clear, they are using a quality 40W Epilog Zing ...

One of the main challenges is the control over the etching process, particularly in terms of the etch rate uniformity, surface roughness, and feature size variability. The development of advanced ...

With highly-selective etch, a specialized etch tool removes or etches away materials in tiny chip structures during the IC production process. In addition, these highly-selective etch tools have the ...

Atomic layer etching (ALE) is a highly controlled and selective etching technique that removes material layer by layer at the atomic scale. It is a cyclic process that relies on self-limiting chemical ...

However, the process, known as reactive ion etching, isn't fully understood and could be improved. One recent development involves keeping the wafer––the sheet of semiconductor material to be ...
