Patent ID: 8153451

Claim:
A method of performing a semiconductor process on a target substrate, the method comprising the steps of: causing a transfer device driven by a drive section, to transfer the target substrate onto a support member; causing a process chamber to accommodate the support member supporting the target substrate, and perform the semiconductor process on the target substrate; causing a measuring section to measure a characteristic of a test target film formed on the target substrate by the semiconductor process; causing an information processing section connected to the measuring section to calculate a positional correction amount of the target substrate necessary for improving planar uniformity of the characteristic, based on values of the characteristic measured by the measuring section at a plurality of positions on the test target film, wherein the positional correction amount is directed to a horizontal coordinate position at which the target substrate is supported on the support member; and causing a control section connected to the information processing section to control the drive section, based on the positional correction amount, when the transfer device transfers a next target substrate to the support member to perform the semiconductor process, such that the next target substrate is placed on the support member at a horizontal coordinate position corrected in accordance with the positional correction amount.
