Patent number: 6952622Abstract: A wafer cluster tool is described which operates in a regular, periodic fashion. Embodiments of the invention have a periodicity of one sending period. The invention enables the determination of pick-up times for process chambers in the cluster tool, and embodiments of the invention allow the creation and maintenance of an updated timetable.

Robot pre-positioning eliminates the wait time of individual modules beyond queue times which have been pre-determined for the modules. This renders the path of the individual robots pre-deterministic, and enables the cluster tool to utilize single gripper robots.Type: GrantFiled: October 14, 2003Date of Patent: October 4, 2005Assignee: ASML Holding N.V.Inventors: Dikran Babikian, Hilario Oh

Patent number: 6872662Abstract: A method for detecting the endpoint of a chemical mechanical polishing (CMP) process uses the slope variation of temperature difference of polishing pad. The method combines temperature measurement at polishing pad and atmosphere, and numerical analysis to figure out the curve of temperature difference variation versus polishing time. The endpoint of CMP is determined by the change of the slope of the curve. The method allows endpoint to be detected in-situ at the polishing apparatus, without stopping polishing process.Type: GrantFiled: October 27, 2003Date of Patent: March 29, 2005Inventors: Hong Hocheng, Yun-Liang Huang

Publication number: 20040166689Abstract: The conveyance of wafers in bays (equipment groups) of a clean room is performed by RGVs (Rail Guided Vehicles) that linearly travel on conveying rails (3) laid on the floor of the clean room at high speed. A structure is adopted wherein a conveying area over which the RGV travels, is separated from a human working area by a compartment (partition) (4), and a human does not enter the conveying area upon operation of a line.Type: ApplicationFiled: April 15, 2004Publication date: August 26, 2004Inventors: Takayuki Wakabayashi, Toshiyuki Uchino, Yasuo Kiguchi, Atsuyoshi Koike

Patent number: 6767846Abstract: A method of securing a substrate in a semiconductor processing machine. The method includes moving latch bodies between latched and unlatched positions while permitting contact between a clamping member of each latch body and the substrate only if the latch bodies are substantially in the latched position. In the latched position, the clamping members apply a clamping force effective to secure the substrate. Generally, contact is prevented by engagement between a support member and an ramp that is inclined such that the clamping member descends toward the substrate as the latch body moves from the unlatched position to the latched position and only contacts the substrate as the latched position is established.Type: GrantFiled: June 27, 2003Date of Patent: July 27, 2004Assignee: Tokyo Electron LimitedInventors: Stanislaw Kopacz, John Lawson
