摘要:
The present invention generally provides a robot that can transfer a workpiece, such as a silicon wafer, at increased speeds and accelerations/decelerations. More particularly, the present invention provides a robot wrist for mechanically clamping a workpiece to a workpiece handling member of an extendable robot arm. The wafer clamp selectively applies sufficient force to center the workpiece and prevent slippage and damage to the workpiece during rapid rotation and radial movement of the handling member. In one embodiment, a clamp for securing silicon wafers uses two independent clamp fingers to position and hold the wafer with minimal particle generation and wafer damage. The clamp is designed so that wafers are normally clamped except during full extension of the wafer handling member to deliver or pickup a wafer.

A substrate transporting robot apparatus is disclosed which is adapted to transport a substrate to and from a chamber of an electronic device processing system. The apparatus may include an upper arm rotatable in an X-Y plane, a forearm rotatable relative to the upper arm in the X-Y plane, and a wrist member rotatable relative to the forearm in the X-Y plane, the wrist member including an end effector adapted to carry a substrate. The wrist member may be subjected to independent rotation such that various degrees of yaw may be imparted to the wrist member. In some aspects, the independent rotation is provided without a motive power device (e.g., motor) being provided on the arms or wrist member, i.e., the wrist member may be remotely driven. Systems and methods using the robot apparatus are also provided as are numerous other aspects.

A conveyor apparatus adapted to transport and article is provided. The conveyor apparatus has a belt section including a plurality of slots and a plurality of T-shaped stiffeners extending in the slots. Respective belt sections may be spliced together using a plurality of T-shaped stiffeners extending through slots in diagonally-formed ends of each belt section. Methods of the invention are described as are numerous other aspects.

Methods and apparatus are provided for the use of a dual Selective Compliant Assembly Robot Arm (SCARA) robot. In some embodiments two SCARAs are provided, each including an elbow joint, wherein the two SCARAs are vertically stacked such that one SCARA is a first arm and the other SCARA is a second arm, and wherein the second arm is adapted to support a first substrate, and the first arm is adapted to extend to a full length when the second arm supports the first substrate, and wherein the first substrate supported by the second arm is coplanar with the elbow joint of the first arm, and the second arm is further adapted to move concurrently in parallel (and/or in a coordinated fashion) with the first arm a sufficient amount to avoid interference between the first substrate and the elbow joint of the first arm. Numerous other embodiments are provided.
摘要:
An adjustable length frog-leg type wafer handler is provided. The wafer handler has two arms each having an upper portion and a lower portion. The lower portion may extend between a normal position and an extended position, and/or the upper portion may extend between an normal position and a compressed position. The adjusted positions (i.e., extended or compressed) are assumed as the wafer handler moves through a center position. Thus, the inventive wafer handler has a normally smaller arm length (as compared to conventional frog leg configurations) which in turn allows a smaller core axis of rotation (i.e., a smaller bladeless arm length). Therefore the blade used with the adjustable wafer handler may be longer by an amount equal to the difference between the normal and the adjusted arm lengths, without increasing the overall (i.e., the length of the arm and blade) retracted axis of rotation. The longer blade allows wafer placement within a processing chamber without requiring the wafer handler itself to enter the processing chamber.

An electronic device manufacturing system is disclosed. The system includes a processing tool having one or more processing chambers each adapted to perform an electronic device manufacturing process on one or more substrates; a substrate carrier adapted to couple to the system and carry one or more substrates; and a component adapted to create a sealed environment relative to at least a portion of the substrate carrier and to substantially equalize the sealed environment with an environment within the substrate carrier. Methods of the invention are described as are numerous other aspects.
摘要:
Systems, apparatus and methods for transporting substrates between system components of an electronic device manufacturing system are provided. The systems and apparatus include an electrostatic end effector having a base, an electrode pair on the base, and spacer members for spacing the substrate from the electrode pairs to provide a gap between the electrode pair and the substrate. Methods of the invention as well as numerous other aspects are provided.
摘要:
Substrate transport systems, apparatus, and methods are described. The systems are adapted to efficiently put or pick substrates at a destination by rotating a boom linkage to a position adjacent to the destination and then independently actuating an upper arm link housing and one or more wrist members to put or pick one or more substrates at the destination wherein the wrist member is independently actuated relative to the forearm link housing and the motion of the forearm link member is kinematically linked to the motion of the upper arm link housing. Numerous other aspects are provided.
摘要:
In a first aspect, a substrate carrier is provided that includes an enclosure adapted to be sealable and to house at least one substrate. The substrate carrier includes a first port leading into the enclosure and adapted to allow a flow of gas into the enclosure while the substrate carrier is closed. Numerous other aspects are provided.
