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 ...

the plating and etching rates in certain instances are sufficiently rapid to make them competitive with batch processing methods. This is particularly interesting as it pertains to laser-enhanced jet ...
