In chip manufacturing, there is an “invisible hero”—without it, multi-layer metal circuits would resemble “uneven mountain roads,” making precise lithography impossible, and achieving 7nm or 5nm processes would be a fantasy. This hero isChemical Mechanical Polishing (CMP), which can control the surface undulations of silicon wafers within 50Å (0.005μm), achieving true “global flattening.” Today, we … Read more

The key material in the photolithography process is photoresist, which mainly consists of organic resins, photosensitive compounds, and solvents. Additionally, it needs to be resistant to corrosion and ion … Read more
1 Silicon Wafers Are Important Semiconductor Materials, With A Scale Exceeding 10 Billion USD Silicon wafers are the most demanded semiconductor materials Semiconductor materials are a class of electronic materials that possess semiconductor properties (conductivity between conductors and insulators) and can be used to make semiconductor devices and integrated circuits, forming the foundation of the … Read more
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
