Chromium etchant is a chromium based solution that removes the excess metal from the substrate. These etchants are majorly used in metal finishing and electronic industry. It has an etch rate of 4 mm/s and can be used to etch nickel, copper, and chromium based excess metals.

WebMar 15, 2024 · On the contrary, dry etching techniques are usually highly anisotropic and less selective. Dry etching, such as ion milling or reactive ion etching (RIE), can produce vertical profiles, but may induce damage due to ion bombardment effects or induce hydrogen contamination on the AlN film, changing its conductivity [ 18 ].
WebOct 30, 2007 · We investigated the CD MTT control of the attenuated PSM (Phase Shift Mask) by additional Cr dry etch. In conventional process, it is difficult to control CD MTT precisely because about 5 factors - Blank Mask, E-beam writing, Resist develop, Cr dry etch, MoSiN dry etch - affect CD MTT error. We designed the new process to control … broby bed and breakfastWebThe dry etching rate of a Cr film has been increased by adding ethyl or methyl alcohol vapor to an etchant gas containing a halide of a hydrocarbon such as CCl 4 and oxygen gas. The dry etching rate increase is attributed to the reduction reaction of a dry etching product, CrO 2 Cl 2, into chemically stable CrCl 3, the reduction reaction suppresses … broby industrilakeringWebAlso, dry etch parameters can be precisely controlled via a microprocessor- controlled etch system with a highly accurate parameter-metering system that ensures greater process control.
