Проверка микросхем (простейший метод).

A simple test of digital microcircuits is shown here Integrated (micro)circuit (IC, IMS, IC (English)), microcircuit, microchip, chip (English chip "thin plate": originally the term referred to the plate of the microcircuit crystal) is a microelectronic device - an electronic circuit of arbitrary complexity (crystal), manufactured on a semiconductor substrate (plate or film) and placed in a non-separable case or without one in the case of inclusion in the composition of a microassembly. Most microcircuits are manufactured in cases for surface mounting. Often, an integrated circuit (IC) is understood to mean the crystal or film with an electronic circuit, and a microcircuit (MC) is an IC enclosed in a case. At the same time, the expression chip components means "components for surface mounting" (as opposed to components for soldering into holes on a board). In the manufacture of microcircuits, the photolithography method (projection, contact, etc.) is used, with the circuit being formed on a substrate (usually silicon) obtained by cutting silicon monocrystals into thin plates with diamond disks. Due to the small linear dimensions of the microcircuit elements, the use of visible light and even near ultraviolet radiation for illumination was abandoned. The minimum controlled dimensions of the photorepeater topology (contact windows in silicon oxide, the width of the gates in transistors, etc.) and, as a consequence, the dimensions of the transistors (and other elements) on the crystal are indicated as characteristics of the technological process of microcircuit production. This parameter, however, is interdependent with a number of other production capabilities: the purity of the resulting silicon, the characteristics of the injectors, the photolithography methods, the etching and sputtering methods.
