Function: A mask is a representation of the layout of a layer of an integrated circuit and is made from the constructions plans for that circuit. A high energy UV-light is shone through the mask onto a silicon wafer which is a coated with photosensitive film, thus imprinting the areas of the wafer not covered by the mask. Additional layers of photosensitive material and different masks are used to build the circuit layer by layer, and metal coating is used to form the wires of the integrated circuit.
