In the international semiconductor statistics, the semiconductor industry is only divided into four types: integrated circuits, discrete devices, sensors and optoelectronics. All international semiconductor trade is divided into these four categories.
These four categories can be collectively referred to as semiconductor components. The Integrated Circuit (Integrated Circuit, referred to as IC), also known as chip (chip), so integrated circuit, IC, chip, chip these four names all refer to one thing.
According to the classification of different processing signals, all integrated circuits can be divided into analog chips and digital chips. Chips that process analog signals are called analog chips, and chips that process digital signals are called digital chips.
1. Radio chip
2. Power semiconductors
3. Analog chip
4. Memory chips
