Here’s a step-by-step guide for printing etch resist directly to copper clad ... In order to feed substrate through the device it needs some physical alteration to make room for the thickness ...

Lam Research Corp. (Nasdaq: LRCX) today announced the donation of its innovative multi-chamber semiconductor etching system ...

Reactive Ion Etch (RIE) is a physical etch process. A rich plasma has been made just above the wafer, and the ions are expedited toward the surface to generate a highly powerful anisotropic etch.

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) ...
