Thickness Available to Substrate:3 Quartz: One of the most important steps in the 1X photolithography process is mask alignment. A mask or photomask is a square glass plate with a patterned film on one side. The mask is aligned with the wafer, so that the pattern can be transferred onto the wafer surface. Each photomask must Glass photomask Selba S.A. - GenevaGlass photomask We produce our photomasks in Sodalime glass or quartz (fused silica) in several precision ranges in order to best meet your needs. Our team will advise you on the manufacturing process of your photomask to guarantee a product suited to your requirements.

The T-4000 series of synthetic quartz glass is extremely pure, with metal impurities less than one-tenth that of ordinary quartz glass. The glass is highly homogenous and contains few striae or bubbles, thus yielding excellent ultraviolet transmittance.
