Lithographic processing

WebPhotolithography is a subclass of microlithography, the general term for processes that generate patterned thin films. Other technologies in this broader class include the use of steerable electron beams, or more rarely, nanoimprinting, interference, magnetic fields, or scanning probes. WebLithography is a planographic printmaking process in which a design is drawn onto a flat stone (or prepared metal plate, usually zinc or aluminum) and affixed by means of a chemical reaction. First, the design for the lithograph is drawn directly onto a polished slab of limestone using an oil-based lithographic crayon or ink.
