The product can etch Al, Cr, Cu, Ni, GaAs. It can surface oxidize Si, Ta/TaN, however, it has no effect on Au, Si 3 N 4, SiO 2, Ti, and W surfaces. Features and Benefits. Designed for precise, …

Cr etch 210 Chromium Etchant . General Information. Cr etch 210 is an alkaline etchant for Cr. The etchant is used for the wet-chemical patterning or removal of thin Cr layers with selectivity …

2001年5月1日 · However, using the mixtures, Cr etch characteristics changed remarkably as shown in Fig. 1. This figure implies that very volatile etch products were formed by the surface …

With a good approximation, a chromium undercut proceeds with the same speed of film etching. This means that a 100 nm thick film is associated to 100 nm undercut on both sides of the …

2021年4月7日 · The proposed mixture performs with Cr etch rates (ERs) up to 400 nm/min at 300 W platen power and is highest when the SF 6 /O 2 gas ratio is ∼0.75%, i.e., almost pure O 2 …

Cr-etch-210 is specialised for the patterning of Cr layers using resist mask patterns. For applications without photo resist mask, e.g. for the removal of seed layers after plating process …

2021年3月23日 · Chromium Etch 1020 is a ceric ammonium nitrate/ nitric acid based etchant that is used to etch chromium at a rate of 13Å/sec or 750A/min. This chemical is manufactured by …

The sum formula for the etching of chromium with ceric ammonium nitrate and perchloric acid is 3 (NH 4) 2 Ce(NO 3) 6 + Cr Cr(NO 3) 3 + 3(NH 4) 2 Ce(NO 3) 5 according to which the cerium …
