Chromium dry etch
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 ]. Webetching of chrome reticles currently has little penetration into commercial reticle fabrication due to lack of economical equipment and etch processes with adequate resist to …

WebWe have investigated Cr film etching mechanism systematically in order to minimize CDU (CD Uniformity). As a result, employing our dry etching system ARESTM with optimized etch process we achieved an excellent CDU(3σ) (0.5nm with etch contribution). Cr film has been widely used not only for the light-shielding film at Cr Binary Mask but also as a hard … WebPrecise measurement of chromium dry etching rate at low temperatures for ultimate profile control Daniel Staaks a,b, XiaoMin Yang c, Stefano Dallorto a, Scott Dhuey a Simone Sassolini a, Kim Y Lee c, Ivo W.

WebJan 22, 2001 · In this paper we describe the development of a chrome dry etch process on a new type of mask etch tool. One crucial goal was to minimize the CD etch bias. To meet this goal, a procedure for the direct characterization of CD etch bias was developed. The common methods for measuring the CD etch bias as resist-to-chrome CD difference, … WebJan 1, 2012 · To produce such etching depth, a Cr hard mask is needed. Wet etching process for Cr film was selected to form the Cr hard mask. In this study, the interactions …
