WebbScum-free, UVN™ resist is the optimal solution for deep-trench patterning. SL™ Resist is our low-temperature resist that bakes at less than 100C. It features high resolution and is suitable for small pattern sizes. EPIC™ Photoresists. EPIC™ Photoresists are a series of 193 resists widely used for 193 processes with and without topcoats. Webbsensitivity of the photoresist • A photo-acid is created in PR when it exposes to DUV light • During PEB, head-induced acid diffusion causes amplification in a catalytic reaction • Acid removes protection groups • Exposed part will be removed by developer.

Webb5 mars 2013 · Positive photoresists are able to maintain their size and pattern as the photoresist developer solvent doesn’t permeate the areas that have not been exposed to the UV light. With negative resists, both the UV exposed and unexposed areas are permeated by the solvent, which can lead to pattern distortions. WebbPhotoresists are one of the very important components in lithography. Photoresists can be classified as organic or inorganic according to their major composition.
