In semiconductor manufacturing, a mask is sometimes called a reticle. [1] [2] In photolithography, several masks are used in turn, each one reproducing a layer of the completed design, and together known as a mask set. A curvilinear photomask has patterns with curves, which is a departure from conventional photomasks which only have patterns ...
semiconductor – a material with an electrical conductivity value falling between that of a conductor and an insulator; its resistivity falls as its temperature rises; silicon – the semiconductor material used most frequently as a substrate in electronics; silicon on insulator (SoI) – a layered silicon–insulator–silicon substrate
The United States Code (USC) defines a mask work as "a series of related images, however fixed or encoded, having or representing the predetermined, three-dimensional pattern of metallic, insulating, or semiconductor material present or removed from the layers of a semiconductor chip product, and in which the relation of the images to one ...
A variety of reticles, each appropriate for one stage in the process, are contained in a rack in the reticle loader, usually located at the upper front of the stepper. Before the wafer is exposed a reticle is loaded onto the reticle stage by a robot, where it is also very precisely aligned. Since the same reticle can be used to expose many ...

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.
