  • Patent number: 7461882
    Abstract: Apparatus and processes are disclosed that provide a microfabricated microtool having a mechanically actuated manipulating mechanism. The microtool comprises a tweezer having flexible arms, and an actuating mechanism. A biological, electrical, or mechanical component is grasped, cut, sensed, or measured by the flexible arms. The actuating mechanism requires no electric power and is achieved by the reciprocating motion of a smooth, rigid microstructure applied against the flexible arms of the microtool. In certain implementations, actuator motion is controlled distally by a tethered cable. A process is also disclosed for producing a microtool, and in particular, by micropatterning. Photolithography may be used to form micro-molds that pattern the microtool or components of the microtool. In certain implementations, the tweezer and actuating mechanism are produced fully assembled. In other implementations, the tweezer and actuating mechanism are produced separately and assembled together.

  • Patent number: 6764120
    Abstract: A material holding implement including a material holding member adapted for holding a material. The material holding member is made of a thermoplastic resin. The thermoplastic resin is deformable to a material holding configuration at a temperature greater than a constant temperature, and fixable to form a material holding region adapted to apply holding forces on a circumference of the material in a using temperature range lower than the constant temperature. Furthermore, a method of changing a form of the material holding member is provided. The method includes softening the resin by increasing a temperature above the constant temperature, molding the resin into a flat plate by pinching together upper and lower dies having flat surfaces opposing each other, pinching the resin using the upper and lower dies to form a material holding configuration, and fixing the resin by decreasing the temperature below a softening point of the resin.

  • Publication number: 20040113444
    Abstract: 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.

  • Patent number: 6652015
    Abstract: The invention relates to a gripper device. According to one aspect, the gripper device includes fingers with grasping ends. The gripper device includes a mechanism to cause the grasping ends to open and close. When the mechanism is engaged, the grasping ends open and close to define a circumference. According to another aspect, the gripper device includes fingers, an upper flat member, and a lower flat member. The fingers have grasping ends. The fingers are inserted into the upper flat member and lower flat member. When the upper flat member is rotated relative to the lower flat member, the grasping ends of the fingers open and close. According to another aspect, a gripper assembly has a gripper device with fingers and a rotating member. The gripper assembly also has a motor and mechanism for rotating the rotating member. The gripper device opens or closes the grasping ends in response to the rotation of the rotating member.

  • Patent number: 6648389
    Abstract: A microtool for manipulating components is proposed. A component is held with the microtool by at least one gripper arm having a gripping surface, the gripper being movable by an actuator structure. Also provided is a device for releasing the held component from the gripping surface, whereby an acceleration is induced in the gripper arm for at least a time, and the force of inertia resulting from the inertial mass of the held component and the exerted acceleration will be greater than any force of adhesion acting between the held component and the gripping surface. A process is also proposed for producing a microtool or a microtool part, in particular a microgripper by micropatterning.

  • Publication number: 20030197388
    Abstract: A robot arm having wafer-scratching prevention function is disclosed. A touch control method is used in the robot arm to detect the abnormal situation of scratching a wafer, thereby promptly stopping the motion of robot arm from continuously accessing the wafer, so as to prevent a large amount of wafers from scrapping. The robot arm having wafer-scratching prevention function has an electrically conductive layer and an electrically non-conductive layer, wherein the non-conductive layer is located on one surface of the robot arm contacting a target wafer to be accessed, and the conductive layer is on the other surface opposite to the non-conductive layer. The conductive layer is connected to a circuit to generate a stopping signal for stopping the robot arm from continuously accessing the wafer.
