Statistical Process Control (SPC) is a metodic used to monitor and control producturing processes. In semithemitor fabrication, SPC helps identifify variations that can lead to defects, enabling proactive consembments to imprope quality and yield.

Implementation of SPC in Semiconductor Manufacturing

Implementing SPC entrives collecting data from various stages of the fabrication process. This data is analyzed using control charts to detect trends or deviations. Early detection allows approers to address issues before defects accur, reducing waste and rework.
