The boat was fully filled with dummy wafers, and there are three tested wafers per run. The three tested wafers were placed at slot number 6, 15 and 24. The average silicon dioxide thickness and the percent of film non-uniformity over the boat were calculated form those three test wafers. And the average silicon dioxide thickness and the percent of film non-uniformity over the wafer was calculated from the wafer slot no.15, which was placed in the middle of the boat.
