dry etching generally refers to methods like laser etching, where a high-power laser is used to ablate copper from the underlying substrate to create traces, or plasma etching, which uses RF ...

Copper’s optical absorption of blue light ... The thickness and composition of the layers, and the size and shape of the laser etching, can all be chosen to determine the laser’s properties ...

Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, ...

[Brain] wanted to mark some scissors with his Ortur laser engraver. The problem? The laser won’t cut into the hard metal of the scissors. His solution? Smear the scissors with mustard.

That's exactly what scientists at IBM have done using a powerful type of laser called an excimer laser. The average human hair is about 100 micrometers thick. That's really thin. So, thin ...
