What process does POLY do in semiconductors? In semiconductors, POLY is the process of making polysilicon.
Polycrystalline silicon (POLY) is widely used in the manufacturing process of semiconductor devices, mainly used as gate, interconnect, and filling materials. For example, in planar IGBT devices, polysilicon is used for gate and interconnect materials; In the manufacturing process of IGBT products, polycrystalline silicon is used as the groove filling material.
In the semiconductor process,poly is a polysilicon process.
