The basic material is a semiconductor IS monocrystalline semiconductor chips plate, the volume and the surface of the molded chip elements, interconnections and contact area. Semiconducting material usability chips plate determines many physical, chemical and technological properties of the set. As the main characteristics to be mentioned: the restricted zone width, mixed with elements of the electron energy levels in the state; conductivity change capability leģējot plataforma eleven (the maximum and minimum value); lādiņnesēju mobility and life time; thermal conductivity; melting point; oxide characteristics; plataforma eleven good single crystals of acquisition opportunities. The most widely used in silicon semiconductor IR, elemental semiconductors germanium is still in use. Electrophysical and optimal technological parameters set: Integrated semiconductor chips, which are decisive for active elektroradioelementi diodes, transistors, lauktranzstosi or device to charge link is silicon. Silicon device technology, and many operations resulting from the silicon dioxide insulator and a good protective layer properties. Alloying silicon used in the periodic system the third and fifth groups (B, P, As, Sb) diffusion coefficients of SiO2 films is several orders of magnitude lower than in silicon. plataforma eleven It allows leģējot silicon diffusion process, the use of SiO2 as a mask. SiO2 layer of minimum thickness determined plataforma eleven by the emerging diffusion layer thickness. The SiO2 mask based on the use of planar silicon devices and IR technology. SiO2 layer is protected plataforma eleven by a well-prepared silicon devices plataforma eleven operating conditions of external influences. Integrated chip crystal electrical connection to the chip outputs Corps is the most appropriate gold wire, sometimes also used for aluminum wire. [1] ...
Microelectronics is the science and technology sector, covering issues related to the creation of electronic systems using microelectronic products. For microelectronic products called electron devices with a high degree of miniaturizācjas. At microelectronic products include: 1 Integrated plataforma eleven circuits (IS). IS contains a series of electrically connected parts or components plataforma eleven that are constructively formulated as a separate product with a high cell density. 2 Functional Devices (akustoelektroniskas, optoelectronic, ions, etc.). 3 microcomponents - radio radio parts and components mikroizpildījumā: constituents, many layers of printed circuit boards, structural elements, indicators, etc. Microelectronic Device miniaturization plataforma eleven has reached the level at which the element dimensions begin to affect the electrophysical properties of solids. In addition, it appears that certain elements of the parameters are not directly measurable. [1]
