Wafers are the fundamental raw materials for manufacturing semiconductor devices. High-purity semiconductors are prepared into wafers through processes such as crystal pulling and slicing. These wafers undergo a series of semiconductor manufacturing processes to form extremely tiny circuit structures, which are then cut, packaged, and tested to become chips, widely used in various electronic devices. … Read more
Semiconductors A semiconductor is a material whose electrical conductivity is between that of a conductor and an insulator. Its electrical properties are highly sensitive to temperature and the types and amounts of impurities it contains. Semiconductors are the raw materials for manufacturing transistors. Their widespread application is primarily due to the significant variations in their … Read more
1 Concept of Advanced Semiconductor Packaging Industry (1) Concept Packaging is the final process in semiconductor manufacturing. Semiconductor packaging is the process of further processing tested wafers to obtain independent chips, with the aim of adding functionality to the chip’s contacts that can connect to external circuits, such as adding pins to connect with external … Read more
