Description

technical field

[0001] The invention is a miniaturized high-density system-level logic circuit, which belongs to the technical field of system circuits. Background technique

[0002] Since the 1990s, portable, miniaturized electronic products, aerospace, and military electronics have entered a period of rapid development, requiring semiconductor devices to maximize miniaturization, light weight, and high density while meeting high reliability. Integrated circuit technology came into being. However, the current process technology of integrated circuits has approached its physical limit, and Moore's Law will not be maintained. In this context, System in Package (SIP) is proposed as an important technology of "More than Moore". The concept of "Moore's Law" focuses on the level of system integration and provides a new direction for the development of the electronics industry.
