WebMay 11, 2014 · The etch solution still requires a ligand to form soluble complexes, and an underlying conductive layer (e.g. TiW) is also necessary to supply the current. One advantage of this approach is that, by careful consideration of current distribution and mass transport effects, it is possible to achieve a more anisotropic etch profile (i.e. reduced ... WebTiW-etch-200 is applied as etchant for titanium-for the wet-chemical patterning of TiW-layers with selectivity to metals like Au, Pt, Ni, Cr. Usual applications are found in the semiconductor or microsystem technology field for etching adhesion layers or diffusion barriers. Advantages and Requirement Profile
