Silicon wafers are the carriers of most chips. But a piece of silicon wafer hides many unknown details, such as: What are the crystal orientations of silicon wafers? How many positioning flats are there? How is the positioning flats positioned? What is the difference between the positioning flat and Read More

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

1. Definition and function of Dummy WaferDummy Wafer is a wafer specially used to fill machine equipment during wafer manufacturing. It is usually not used in actual production and will not be sold directly as a finished product. Its main function is to meet the specific requirements or constraints Read More

At a GlanceChip shortages in some sectors will begin to ease later this year, including among automotive and industrial companies.Other industries, including gaming consoles and computer servers, won’t recover until 2024.Leading companies are making investments to address short-term supply disruptio 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

Single crystal silicon wafer, referred to as silicon wafer, is a circular sheet-like material whose atoms have been artificially rearranged, and is a high-purity semiconductor material with a crystal orientation. Since silicon accounts for 26% of the mass of the earth's crust, single crystal silicon 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
