Webb17 juni 2024 · In semiconductor manufacturing, chemical mechanical polishing (CMP) is a critical process for creating smooth, flat surfaces on semiconductor wafers. The pressure at which the CMP process is performed is a critical factor in determining the quality of the finished product. If the pressure is too high, it can damage the semiconductor material.
