One-piece inductor

An integrated circuit (IC) is also called an integrated circuit. Refers to an advanced microelectronic device that integrates many microelectronic devices on a chip. Silicon-based materials are commonly used on which N-type and P-type semiconductors and P-N junctions are formed by diffusion or infiltration techniques. There are also chips based on gallium arsenide (GaAs) in the laboratory, which far exceeds the silicon chip, but it is not easy to mass-produce and the price is too high.

An integrated circuit is a semiconductor integrated circuit, that is, a semiconductor material is used as a substrate, and at least one of two or more components of the active component and some or all of the interconnections are integrated in the substrate or on the substrate to perform a certain An intermediate or final product of electronic functions;

The types of integrated circuits are generally classified by the number of electronic components such as transistors.

· SSI (small integrated circuit), the number of transistors is 10~100

· MSI (Medium-sized Integrated Circuit), the number of transistors is 100~1,000

· LSI (Large Scale Integrated Circuit) with 1,000 to 10,000 transistors

· VLSI (Very Large Scale Integrated Circuit), the number of transistors is 100,000~

An integrated circuit layout design refers to a three-dimensional configuration in which an integrated circuit has two or more and some or all of the interconnections of the active elements, or a three-dimensional configuration prepared for the fabrication of the integrated circuit.
