Semiconductor deviceA semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum tubes in most applications. They conduct electric current in the solid state, rather than as free electrons across a vacuum (typically liberated by thermionic emission) or as free electrons and ions through an ionized gas.
Production–possibility frontierIn microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two goods that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time. A PPF illustrates several economic concepts, such as allocative efficiency, economies of scale, opportunity cost (or marginal rate of transformation), productive efficiency, and scarcity of resources (the fundamental economic problem that all societies face).
Process variation (semiconductor)Process variation is the naturally occurring variation in the attributes of transistors (length, widths, oxide thickness) when integrated circuits are fabricated. The amount of process variation becomes particularly pronounced at smaller process nodes (
XerographyXerography is a dry photocopying technique. Originally called electrophotography, it was renamed xerography—from the n roots ξηρός xeros, meaning "dry" and -γραφία -graphia, meaning "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals. Xerography was invented by American physicist Chester Carlson, based significantly on contributions by Hungarian physicist Pál Selényi. Carlson applied for and was awarded on October 6, 1942.
Canon Inc.Canon Inc. (キヤノン株式会社; Hepburn: hepburn) is a Japanese multinational corporation headquartered in Ōta, Tokyo, specializing in optical, imaging, and industrial products, such as lenses, cameras, medical equipment, , printers, and semiconductor manufacturing equipment. Canon has a primary listing on the Tokyo Stock Exchange and is a constituent of the TOPIX Core 30 and Nikkei 225 indexes. It used to have a secondary listing on the New York Stock Exchange. The company was originally named hepburn (精機光学研究所).
Nikon(ˈnɪkɒn, ˈnaɪkɒn; ɲiꜜkoɴ), also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan; it specializes in creating and marketing optics and imaging products. The companies held by Nikon form the Nikon Group. Nikon's products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer.
Photographic processingPhotographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive . Photographic processing transforms the into a visible image, makes this permanent and renders it insensitive to light. All processes based upon the gelatin silver process are similar, regardless of the film or paper's manufacturer. Exceptional variations include instant films such as those made by Polaroid and thermally developed films.
