Describe how statistical process control (SPC) is used to monitor and improve yield.

Question

Accepted Answer

SPC is used to monitor and improve yield by analyzing process data to detect variations and make adjustments.

SPC involves collecting data on key process parameters and using statistical tools to analyze trends and patterns.
By monitoring variations in the process, SPC helps identify potential issues before they impact yield.
SPC allows for real-time adjustments to be made to the process to maintain or improve yield levels.
Examples of SPC tools include control charts, histograms, and Pareto analysis.
By implementing SPC, yield engineers can optimize processes and reduce waste, leading to higher overall yield.
