Upon evacuation of the volume defined between the groove and the tape, the tape is drawn down into the groove and stretched, thereby increasing the separation or gap between adjacent dice and reducing the risk of damage upon removal of the dice.Type: GrantFiled: March 1, 2007Date of Patent: January 26, 2010Assignee: Delphi Technologies, Inc.Inventor: M.

Patent number: 7644968Abstract: A supporting structure is mounted on a hand body facing a circumferential edge of a substrate from below the substrate to support the substrate. First and second guiding members are mounted on the hand body, and having guiding surfaces in contact with an imaginary cylinder having an axis aligned with a reference axis of the hand body. First and second movable members are capable of moving in an imaginary plane perpendicular to the reference axis and are disposed on the radially outer-side of the circumferential edge of the substrate so as to face the circumferential edge. A driving unit simultaneously displaces the first and second movable members in the imaginary plane. The first and second guiding members and the first and second movable members are spaced apart on the circumference of the imaginary cylinder at intervals greater than the length of the arc of a segment in a substrate holding state.Type: GrantFiled: January 21, 2005Date of Patent: January 12, 2010Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Yasuo Hirooka, Yasuhiko Hashimoto, Kei Watanabe

Patent number: 7641247Abstract: Generally, an end effector assembly for a substrate transfer robot is provided. In one embodiment, an end effector assembly for supporting a quadrilateral substrate during substrate transfer includes an end effector having an inner edge support disposed on a first end and a first outer edge support disposed on a distal end. The first end of the end effector is adapted for coupling to a robot linkage. The first inner edge support has a face that is oriented parallel to and facing the face of the first outer edge support. This configuration of edge supports captures the substrate to the end effector thereby minimizing substrate slippage during transfer. In another embodiment, lateral guides may be utilized to further enhance capturing the substrate along the edges of the substrate open between the inner and outer edge supports.Type: GrantFiled: December 17, 2002Date of Patent: January 5, 2010Assignee: Applied Materials, Inc.Inventors: Wendell T. Blonigan, Takayuki Matsumoto, William N. Sterling, Billy C. Leung

Patent number: 7631911Abstract: A transporting arm has two protruding support sections. Front ends of the support sections are formed such that a thickness of the support sections decreases toward the front ends of those. A surface of the transporting arm on which a wafer is placed is provided with a plurality of suction holes formed at equal intervals in a fan-shaped region. The wafer is fixed to the transporting arm through the suction holes. The wafer is charged with a large amount of static electricity. The transporting arm is charged with the static electricity. A surface of the transporting arm is coated with a conductive fluorinated graphite material. Therefore, an electrical discharge rate of the transporting arm into an atmosphere increases. Accordingly, elevation of a surface potential of the transporting arm in a floating state can be appropriately suppressed. Reduction of repulsive force due to the static electricity acting between the transporting arm and the wafer leads to reduction of vibration of the wafer.Type: GrantFiled: February 20, 2007Date of Patent: December 15, 2009Assignee: Seiko Instruments Inc.Inventor: Makoto Aso

Patent number: 7597183Abstract: A kinematic pin and a substrate carrier adapted to deter dislodgment of the substrate carrier from the kinematic pin are provided. A shear member on the kinematic pin interacts with a shear feature of the substrate carrier to deter lateral movement of the substrate carrier relative to the kinematic pin. A substrate carrier handler that employs the kinematic pin is also provided.Type: GrantFiled: October 31, 2007Date of Patent: October 6, 2009Assignee: Applied Materials, Inc.Inventors: Michael R. Rice, Eric A. Englhardt, Robert B. Lowrance, Martin R. Elliott, Jeffrey C. Hudgens
