Why do we need to polish the wafer so smoothly?The final fate of the wafer is to be cut into chips (die), packaged in a dark box, with only a few pins exposed. The chip will look at the threshold, resistance, current value, and voltage value, but no one cares about its appearance. In the process, we Read More

The production of silicon wafers usually has the following steps:1) Crystal growth can be divided into Czochralski method (CZ) and zone fusion method (FZ). Since the molten polycrystalline material will directly contact the quartz crucible, the impurities in the quartz crucible will contaminate the Read More

A silicon wafer is a material essential for manufacturing semiconductors, which are found in all kinds of electronic devices that enrich our lives.Few of us have a chance to encounter an actual silicon wafer in daily life. This ultra-flat disk is polished to a mirror-like surface, and made as free a Read More
