Classification of Semiconductor Wafers Classification of Semiconductor Wafers - Semiconductor Coating - Cheersonic Semiconductor silicon wafers are the basis for the manufacture of silicon semiconductor products and can be classified according to different parameters. According to the size (diameter), semiconductor wafers can be divided into 2 inches (50 mm), 3 inches (75 mm), 4 inches (100 mm), 5 inches (125 mm), 6 inches (150 mm), 8 inches (200 [...]

Development of Semiconductor Materials Development of Semiconductor Materials - Semiconductor Coating - Cheersonic Semiconductor materials are a class of electronic materials with semiconductor properties (conductivity between conductors and insulators) that can be used to make semiconductor devices and integrated circuits, and are the basis of the semiconductor industry. The research of semiconductor materials began in the 19th century and has developed to the fourth generation of semiconductor materials, [...]

Cubic Boron Arsenide Cubic Boron Arsenide - Spray Photoresist Coating Onto MEMS Wafers - Cheersonic A material called cubic boron arsenide overcomes two of the limitations of silicon as a semiconductor: it provides high mobility for electrons and holes, and it has good thermal conductivity. It may be the best semiconductor material ever discovered, researchers say As a semiconductor material, silicon still has shortcomings in its performance. Although [...]

Four Commonly Used Semiconductor Wafer Cleaning As the process nodes of semiconductor integrated circuits become more and more advanced, new requirements are also put forward for several links of actual manufacturing, and the importance of the cleaning link has become increasingly prominent. The key to cleaning is that as the feature size continues to shrink, semiconductors are becoming more and more sensitive to impurity content, and some contaminants [...]

Two days of ice and fire in the chip industry! Two days of ice and fire in the chip industry! Photoresist Coating - Cheersonic Compared with the sound of firecrackers and gongs and drums all over the place last year, today's semiconductor industry is undergoing a "two layers of ice and fire". One is the hot summer of expansion, short supply, and increased capital expenditures, while the other [...]
