Construct ap-chart for the fraction of defective substrates received at a particular point in the production line. One thousand (n=1000)substrates are sampled each week. Remove data for any week for which the process is not in control. Be sure to check for runs as well as points outside the control limits. Construct the revise dp-chart and be sure to check for runs again.
