Patent number: 8181769Abstract: A workpiece transfer mechanism 76 transfers workpieces W to a workpiece boat 40 having ringlike tables 86. The transfer mechanism 76 includes a fork main body 78 being movable forward and rearward with the workpiece W placed thereon; stopper members 94 provided at the end portion of the fork main body 78; clamp means 96 provided on the proximal end side of the fork main body 78 and having a pressing portion 102 coming into contact with the circumferential edge of the workpiece W and pressing the workpiece W toward the stopper member 94 for clamping; and fork elevating means 80 for lifting and lowering the fork main body 78. When the workpieces W are transferred to a workpiece boat 40, the pressing portion 102 of the clamp means 96 is controlled so as not to be inserted into a gap between tables 86. Thus, although the pitch between the tables 86 is small, the pressing portion 102 of the clamp means 96 does not interfere with the workpiece boat 40.Type: GrantFiled: October 14, 2008Date of Patent: May 22, 2012Assignee: Tokyo Electron LimitedInventors: Katsuyuki Hishiya, Kiichi Takahashi, Haruoki Nakamura

Publication number: 20100057249Abstract: When a substrate is transferred by a holding arm to a multiple tier wafer boat, contact between the holding arm and the substrate is prevented. When the wafer boat is not subjected to a thermal effect, a normal height position of a ring member is obtained by relatively elevating and lowering a transfer base member with respect to the wafer boat. Before a wafer, which is not yet thermally processed, is transferred to the wafer boat, a height position of the corresponding ring member is obtained. By comparing a difference between the normal height position of the ring member and the height position of the ring member before the wafer is transported, with a threshold value, whether to transfer the wafer by the wafer transfer mechanism to the wafer boat can be judged.Type: ApplicationFiled: August 27, 2009Publication date: March 4, 2010Applicant: Tokyo Electron LimitedInventors: Yo ABE, Kiichi TAKAHASHI, Junya SATO, Yoshinobu MOTODATE

Patent number: 5857848Abstract: A vertical heat treatment system has a transfer apparatus for transferring semiconductor wafers and a cassette serving as a transport container for the semiconductor wafers. The transfer apparatus has a base disposed to be vertically movable and rotatable within a horizontal plane. Wafer arms for transferring the wafers placed on them are disposed on the base. The wafer arms can reciprocally move on the base between a standby position and an advanced position in the horizontal direction. A cassette arm for transferring a cassette placed on it is also disposed on the base. The cassette arm can reciprocally move on the base between a retreat position and a protruded position in the horizontal direction. The wafer arms and the cassette arm are reciprocally movable in opposite directions to oppose each other. While the wafer arms and the cassette arm are at the standby position and the retreat position, respectively, a holding portion of the cassette arm is present immediately above the wafer arms.Type: GrantFiled: September 10, 1997Date of Patent: January 12, 1999Assignee: Tokyo Electron LimitedInventors: Kiichi Takahashi, Hiroshi Kikuchi
