WebLithographic photomasks are typically transparent fused silica plates covered with a pattern defined with a chromium (Cr) or Fe 2 O 3 metal absorbing film. Photomasks are used at wavelengths of 365 nm, 248 … The root words photo, litho, and graphy all have Greek origins, with the meanings 'light', 'stone' and 'writing' respectively. As suggested by the name compounded from them, photolithography is a printing method (originally based on the use of limestone printing plates) in which light plays an essential role. In the 1820s, Nicephore Niepce invented a photographic process that used Bitumen of Judea, a natural asphalt, as the first photoresist. A thin coating of the bitumen on a sheet of met… high mcv and mch meaning
