Mobile phone IC is defined as semiconductor component products; It is classified as amplifier, memory, charger IC, etc., including integrated circuit, etc.; Mobile phone IC is a general term for semiconductor components used in mobile phones. The mobile phone chip is a classification of IC, the nature is the mobile phone communication function of the chip, band, processor, coprocessor; Important include wireless ics and power management ics; It is a circuit module that collects a variety of electronic components on a silicon board to achieve a certain function. Mobile phone IC includes: 1. integrated circuit (abbreviated :IC); 2. Two, triode; 3. Special electronic components. More broadly speaking, it also involves all electronic components, such as resistors, capacitors, circuit plates \/PCB plates, and many other related products. Mobile phone IC is the use of semiconductor production process, in a small monocrystalline silicon chip to produce many transistors and resistors, capacitors and other components, and in accordance with the multi-layer wiring or tunnel wiring method to combine the components into a complete electronic circuit. In the circuit, the letter \"IC\" (also useful word symbol \"N\
