si wafer sizes
The diameter of a silicon wafer is its size, and the common diameters of silicon wafers are 100mm (4 inches), 150mm (6 inches), 200mm (8 inches) and 300mm (12 inches).
The size of the diameter directly affects the number of chips that can be manufactured on a silicon wafer and the size of the chip, which in turn affects the production cost and chip performance.
si wafer sizes
The size of a silicon wafer is usually expressed in terms of its diameter, and common silicon wafer sizes are:
4-inch (100mm): silicon wafers with a diameter of about 100mm, whose thickness is generally around 525 microns (um).
6 inches (150mm): diameter of about 150mm silicon wafer, its thickness is about 675 microns (um).
8 inches (200mm): diameter of about 200mm silicon wafers, its thickness is about 725 microns (um).
12-inch (300mm): silicon wafers with a diameter of about 300mm, which is currently the mainstream and larger silicon wafer size, with a thickness of about 775 microns (um).
It should be noted that these thickness values are only common specifications, and the thickness of silicon wafers in actual production may fluctuate within an appropriate range based on specific process requirements.
