Patent number: 8831765Abstract: The instant disclosure provides a method for operating an automatic handling system applied to many wafer processing apparatuses. When a OHT (Overhead Hoist Transport) vehicle is moved to one of the wafer processing apparatuses, the OHT vehicle can ask a OHT control module whether a wafer carrier device can be unloaded from the OHT vehicle onto the wafer processing apparatus. There are two judgment methods as follows: (1) If there is another wafer carrier device already disposed on the wafer processing apparatus, the OHT control module will inform the OHT vehicle that the wafer carrier device cannot be unloaded from the OHT vehicle onto the wafer processing apparatus; (2) If there is no any wafer carrier device disposed on the wafer processing apparatus, the OHT control module will inform the OHT vehicle that the wafer carrier device can be unloaded from the OHT vehicle onto the wafer processing apparatus.Type: GrantFiled: December 23, 2011Date of Patent: September 9, 2014Assignee: Inotera Memories, Inc.Inventors: Tsan-I Chen, Jung-Pin Lai

Patent number: 8651025Abstract: An overhead wafer transport system includes an over head transportation (OHT) rail and at least one shuttle. The OHT rail includes a main track and two lateral tracks, each having a hollow transverse cross-section, each lateral track being in corresponding connection with the main track through the two sides thereof, constituting an approximate tri-directional branch form. The shuttle has a track-interface assembly and a docking unit, the track-interface assembly being adapted to travel along the OHT rail. The track-interface assembly being arranged at the junction of the two lateral tracks and the main track, wherein the track-interface assembly is adapted to selectively travel along at least one of the main track and the lateral tracks. Therefore, the overhead wafer transport system can be applied to a clean room with higher transfer efficiency and clean room space utilization.Type: GrantFiled: October 31, 2011Date of Patent: February 18, 2014Assignee: Inotera Memories, Inc.Inventors: Tsan-I Chen, Wen-Yu Fang
