[Arvid] is using the traditional method of etching away copper, just some ferric chloride and a bit of time. How he’s masking the copper that shouldn’t be etched away is a unique process we ...

Much like etching a PCB, Blake started with a copper sheet, writing and drawing his works backwards with stopping varnish, an acid-resistant varnish that sticks around after a nitric acid bath.

Researchers find a faster way to etch deep holes for 3D NAND Plasma-based cryo-etching technique doubles etch speed, ...
