Electron-beam lithography systems can be classified according to both beam shape and beam deflection strategy. Older systems used Gaussian-shaped beams that scanned these beams in a raster fashion. Newer systems use shaped beams that can be deflected to various positions in the writing field (also known as vector scan).

Broaching can refer to two operations, linear broaching, where a multi toothed tool is pressed through a hole to cut a desired shape (e.g. a spline, square, or hex shape) or along a surface by taking increasingly larger cuts by the increasing sized teeth of the broach; or rotary broaching, where a drafted tool is rotated in a special toolholder ...
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
This means that its definition is applicable to all members (instances) of a class. Other ways to define a target of a shape are by: Explicitly saying that a shape targets members of a certain class. This can be done instead of making a node shape also a class. Saying that a shape targets a specific resource by giving its URI.
