Web15 mrt. 2024 · A novel UV contact lithography process is presented to realize diffraction-limited dimensions in the patterning and lift-off of structures. The process involves a tri-layer stack comprising a bottom layer of lift-off resist (LOR), followed by a back anti-reflection coating (BARC), capped by a layer of I-line optimised photo resist (PR). Webover 10 times higher SC-1 resistance than that of conventional BARC. And this novel BARC can be applied both ArF & KrF lithography process because of broad absorbance, high etching rate, chemical resistance (SC-1, SC-2, DHF, and others) and good film thickness uniformity. In this paper, we will discuss the detail of new self-crosslinking BARC in WebIn this study, the blanket etch rates of BARC and gap fill materials used in ArF lithography were examined as a function of the polymer structure, including the dextrin ester polymer. This concept was first demonstrated with the development of BARC and gap fill materials using dextrin with a-glycoside bonds in a polysaccharide. Our goal in this flowers that self seed
