Abstract: The present invention provides an auxiliary tool for assembling a motor assembly to a wafer-deposition machine for supporting a wafer. The auxiliary tool facilitates easy and quick assembly of the motor assembly to the wafer-deposition machine. An aspect of the present invention is directed to an auxiliary tool for assembling a motor assembly to a wafer-deposition machine, wherein the motor assembly includes a plurality of first screw holes and the wafer-deposition machine includes a plurality of second screw holes corresponding to the first screw holes, respectively. The auxiliary tool comprises a plurality of locking members each having a substantially uniform dimension in a longitudinal direction and being configured to be inserted through one of the plurality of first screw holes of the motor assembly with a corresponding one of the plurality of second screw holes of the wafer-deposition machine to align the first screw hole with the corresponding second screw hole.

Abstract: A chamber for a high vacuum system is provided. The chamber is tested by a leakage tester, and comprises a body and an intermediate unit. The body is provided with at least one port. The intermediate unit, disposed on the body, connects with the port in order to communicate with the leakage tester. When the chamber is to be tested by the leakage tester, it can be directly connected with the leakage tester through the intermediate unit. Leakage testing of the chamber is thus simplified and rendered considerably more efficient.
