Etching is also used for surface preparation with minimal metal removal (microetching) during innerlayer oxide coating and electroless or electrolytic plating. Technical, economic, and environmental ...

This can become a problem; if the process is not tightly controlled, the etching reactions can extend underneath the resist layer masking off areas of the future traces of the PCB, potentially ...

An example of directional etching for nanohole arrays of less than 500nm in diameter. (Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types ...

What is Atomic Layer Etching? Atomic layer etching (ALE) is a highly controlled and selective etching technique that removes material layer by layer at the atomic scale. It is a cyclic process that ...

Ferric chloride works as well on brass as it does on copper, and [Switch and Lever] does a good job explaining the chemistry of the etching process and offers some tips on making up etching ...

With the 9060 Series, Hitachi High-Tech will support manufacturing process advancements for cutting-edge semiconductor ...

Certain specialized etchers and etching machines perform photochemical or electrochemical etching or electropolishing of components. In electrochemical or electropolishing techniques, a current is ...
