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
1. Overview Silicon wafers (also known as silicon substrates) are made from purified silicon (99.9999999% to 99.99999999999%), where high-purity polycrystalline silicon is melted and drawn into single crystal silicon rods, then processed through rolling, cutting, grinding, polishing, and cleaning to become the substrate material for manufacturing semiconductor devices. 1.1 Silicon Wafers and the Industrial Chain … Read more
