“By definition, as you etch, selectivity is the ratio between what you’re trying to remove and what you don’t want to remove,” Hutcheson said. In one example, a chipmaker deposits a silicon dioxide ...

UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...

UCLA doctoral student Yilin Wong left a sample out by mistake. It was a small chip made of germanium, topped with thin layers ...

[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 ...

Through via hole fabrication process by deep reactive-ion etching (DRIE): (a) Sample cleaning; (b) Deposition of mask material; (c) Transfer of desired pattern; (d) Desired pattern achieved; (e) ...
