He recently worked out a relatively inexpensive and easy way to etch metals using some chemistry skill and a little bit of electricity. After preparing a set of stencils and cleaning the metal ...

Atomic layer etching (ALE) is the reverse of atomic layer deposition (ALD). ALE can be achieved using sequential, self-limiting thermal reactions. We have recently demonstrated Al 2 O 3 ALE [1-3] and ...

This groundbreaking technique, also referred to as MacEtch or MACE, provides ultra-high anisotropy etching that’s free from damage. It is an innovative approach that effectively addresses the ...
