A wafer has to go through three changes to become a real semiconductor chip: first, the block-shaped ingot is cut into wafers; in the second process, transistors are engraved on the front of the wa...
In the back-end process stage, the wafer (silicon wafer with circuits on the front) needs to be thinned on the back before subsequent dicing, welding and packaging to reduce the package mounting he...
After more than 80 years of development, China’s calcium carbide industry has become an important basic chemical raw material industry. In recent years, driven by the rapid development of the...
