Patent ID: 7179334

Claim:
A system for performing a semiconductor process on a target substrate, the system comprising: a process chamber configured to accommodate the target substrate; a support member configured to support the target substrate in the process chamber; an exhaust section configured to exhaust the process chamber; a supply section configured to supply a process gas into the process chamber; a transfer device configured to transfer the target substrate onto the support member; a drive section configured to drive the transfer device; a measuring section configured to measure a characteristic of a test target film formed on the target substrate by the semiconductor process; and a processor in communication with the drive section and the measuring section, and including, an information processing section configured 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 a transfer control section configured 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 said drive section is configured to place the next target substrate is placed on the support member at a horizontal coordinate position corrected in accordance with the positional correction amount, wherein the information processing section is configured to obtain a process center in the process chamber, based on distribution of the characteristic on a first target substrate that has been subjected to the semiconductor process at a first horizontal placement position on the support member, and to calculate the positional correction amount, based on a misalignment amount of a geometric center of the first target substrate relative to the process center, and wherein the transfer control section is configured to control the drive section to place a second target substrate subsequent to the first target substrate by the transfer device at a second horizontal placement position on the support member which is displaced relative to the first horizontal placement position by the positional correction amount, when the second target substrate subsequent is subjected to the semiconductor process.
