Metal Assisted Chemical Etching (MACE)  - The process of wet chemical etching of semiconductors (mainly silicon) with the use of a metal catalyst, usually deposited on the surface of a semiconductor in the form of a thin film. As a metal catalyst, both noble metals (Au, Pt , Pd , Ag ) and base metals (Fe , Ni , Cu ) can act.

Porous silicon
The MACE process allows the production of porous silicon with photoluminescence.

Black silicon
Black silicon is silicon with a modified surface and is a type of porous silicon. There are several works on obtaining black silicon using MACE technology. The main application of black silicon is solar energy.
