1. The types of integrated circuits are generally classified by the number of electronic components such as transistors contained in them: SSI (small integrated circuit), with 10 to 100 transistors; MSI (medium integrated circuit), with 100 to 1,000 transistors; LSI (large-scale integrated circuit), with 1,000 to 100,000 transistors; VLSI (very large-scale integrated circuit), with more than 100,000 transistors.
2. Classification by function and structure: Integrated circuits can be divided into two categories: analog integrated circuits and digital integrated circuits according to their functions and structures.
3. Classification by manufacturing process: Integrated circuits can be divided into semiconductor integrated circuits and film integrated circuits according to the manufacturing process. Film integrated circuits are further classified into thick film integrated circuits and thin film integrated circuits.
4. Classification by different conductive types: Integrated circuits can be divided into bipola
