1. Introduction to chips What is a chip? A chip is an integrated circuit that can be compared to the brain of an electronic device. The components on a chip can perform various tasks, such as processing information, storing data, performing calculations, and controlling operations. Why is it called a chip? "Core" represents the core and center, and "chip" represents a thin piece or fragment. A chip is a thin piece made of semiconductor materials, which, as the core part of the entire circuit system, integrates key circuit structures.
Definition: An integrated circuit chip is a small, thin silicon-based material that integrates electronic components such as transistors, resistors, capacitors, etc. It is a fundamental component of electronic devices.
Semiconductor products cover everything from basic diodes and transistors to complex integrated circuits and microprocessors. These products play a crucial role in electronic devices, including transistors for amplifying and switching current, diodes for rectifying and stabilizing voltage, and memory devices such as DRAM and flash memory for storing and processing data. Integrated circuits,
Semiconductors have a wide range of applications, almost permeating every aspect of our lives. It is widely used in fields such as electronic products, communication equipment, computers, medical equipment, etc. According to different application fields, semiconductors can be divided into six major sub sectors:
Designing a PCB (Printed Circuit Board) for high-frequency applications requires careful consideration of various factors to ensure signal integrity, minimize losses, and mitigate electromagnetic interference. Here are some key steps and considerations:
In the 1980s, China began to enter the semiconductor industry. In the early days, semiconductor technology mainly relied on imports, while China mainly engaged in simple assembly and testing work. At that time, major enterprises such as Shanghai Hongli and East China Semiconductor had a significant gap between their product technology level and the international advanced level, but it laid the foundation for the Chinese semiconductor industry
