Abstract
A semiconductor process system (10) includes a measuring section (40), an information processing section (51), and a control section (52). The measuring section (40) measures a characteristic of a test target film formed on a target substrate (W) by a semiconductor process. The information processing section (51) calculates a positional correction amount of the target substrate (W) necessary for improving planar uniformity of the characteristic, based on values of the characteristic measured by the measuring section (40) at a plurality of positions on the test target film. The control section (52) controls a drive section (30A, 32A) of a transfer device (30), based on the positional correction amount, when the transfer device (30) transfers a next target substrate (W) to the support member (17) to perform the semiconductor process.
