We are known as the "chip" refers to integrated circuits, microelectronic technology is its main product. Microelectronics is a relative of the so-called "strong power" and "weak" and so on, means it has to deal with the tiny electronic signal. It is the foundation of modern information technology, we often come into contact with the electronics, telecommunications, computers, intelligence systems, automation, space technology, radio, television and so on are all in the micro-electronics technology developed on the basis of.
Microelectronic technology involved in many industries, including chemicals, optical technology, semiconductor materials, precision manufacturing equipment, software and so on, among integrated circuit technology at the core, including IC design, manufacture.
Integrated circuit (IC) used the basic concepts are:
Wafer, refers to the number of single crystal silicon wafer, the silicon from ordinary salad from refining system, is the most commonly used semiconductor material, its diameter is divided into 4-inch, 5-inch, 6-inch, 8-inch, and other specifications, the recent development of 12 Inch or greater specification. The bigger wafers, on the same wafer can produce more on the IC can reduce costs; but requested materials technology and production technology higher.
Before and after the process: IC manufacturing process, the wafer lithography process (the so-called tape), known as the former process, which is the most crucial point of IC manufacturing technology; silicon wafer, the cutting, packaging processes After the process is called.
Lithography: IC production technology of the main means that the technology used in etching circuits on silicon.
Width: 4 microns / 1 micron / 0.6 micro-not / 0.35 / 035 micron, and other means to reach IC production technology of the smallest wire width of IC technology is the advanced level of the main targets. The smaller the width, On the integration, in the same area on the integrated circuit more units.
Packaging: the means circuitry on silicon pin, Jieyin wire to the external connector, in order to connect with other devices.
Memory: dedicated to the preservation of data IC.
Logic: for the principle of binary digital circuit. |
