integrated circuit wafer
IC wafers are the core material in semiconductor manufacturing, and they play a vital role in the electronics industry. IC wafers refer specifically to silicon wafers used in the production of integrated circuits. These wafers are typically made of high-purity single crystal silicon and have a circular form, with diameters commonly ranging from 8 inches (200 mm) to 12 inches (300 mm).

Monocrystalline silicon: used in the manufacture of high-performance semiconductor devices and solar cells, with a complete dot structure, anisotropy is obvious.
Polycrystalline silicon: composed of multiple grains with different grain orientations, commonly used in the production of solar panels, relatively low cost.
Amorphous silicon: irregular structure, used in the manufacture of certain types of solar cells, sensors and displays, with lower manufacturing costs but slightly lower performance.
Manufacturing and Applications:
Manufacturing of monocrystalline silicon is usually done by straight drawing (CZ) or zone fusion (FZ), while polycrystalline silicon is done by fusion casting.
In the electronics industry, crystalline silicon is the core material used in the manufacture of integrated circuits, microprocessors, memory chips, and so on.
In the field of renewable energy, it is the basis of solar photovoltaic technology and is widely used in solar panels.
These properties of crystalline silicon make it an indispensable material in modern electronics and renewable energy technologies.
