Metal Assisted Chemical Etching (also known as MACE) is 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 or nanoparticles. The semiconductor, covered … Meer weergeven The metal assisted chemical etching of semiconductors is a relatively new technology in semiconductor engineering and therefore it is not yet a process that is used in industry. The first attempts of MACE … Meer weergeven As already stated above MACE requires metal particles or a thin metal thin film on top of a silicon substrate. This can be achieved … Meer weergeven Some elements of MACE are commonly accepted in the scientific community, while others are still under debate. There is mutual agreement that the reduction of the oxidizing … Meer weergeven The reason why MACE is heavily researched is that it allows completely anisotropic etching of silicon substrates which is not possible with other wet chemical etching methods (see figure to the right). Usually the silicon substrate is covered with … Meer weergeven WebAlternatively, the pattern can be inverted and metal-assisted etching used, 5 illustrated in Figure 1B, to achieve similar anisotropic structures. Alternate approaches to …
