Abstract:
A series of modular apparatuses for processing substrates using a unique combinations of a substrate coating subsystem, a substrate curing subsystem and a PECVD-based capping subsystem. The individual subsystems are capable of being combined with one another for creating unique integrated substrate processing apparatuses that enable combined processing by the coating, curing and capping subsystems in an integrated and controlled environment, thus enabling the processing of substrates in an efficient manner, while minimizing the exposure of the substrates to an external environment and minimizing the condensation of vapors while the substrate is processed by the cure and capping subsystems.
Abstract:
Embodiments of the present invention are directed to substrate processing systems having substrate transferring mechanisms that are compact, have small footprints, and provide fast and efficient substrate transfer to achieve high throughput. In specific embodiments, a unit slab construction is used for the chambers around the substrate transferring mechanism, enabling efficient system construction with improved alignment and at a lower cost. The chambers may share gas, pump, and other utilizes. In one embodiment, an apparatus for processing substrates includes at least three robot blades each configured to support a substrate. A robot is coupled with the at least three robot blades to simultaneously move the robot blades between at least three chambers and simultaneously transfer each of the substrates supported on the robot blades from one chamber to another chamber.
Abstract:
The present invention generally provides a robot that can transfer workpieces, such as silicon wafers, at increased speeds and accelerations and decelerations. More particularly, the present invention provides a robot wrist associated with the robot arm for mechanically clamping a workpiece to a workpiece handling member attached to the arm. The workpiece clamp selectively applies sufficient force to hold the workpiece and prevent slippage and damage to the workpiece during rapid rotation and linear movement of the handling member. In one embodiment, a clamp for securing silicon wafers uses two clamp fingers connected to a single flexure member to position and hold the wafer with minimal particle generation and wafer damage. The clamp is designed so that wafers are normally clamped except near full extension of the workpiece handling member to deliver or pick up a wafer.
Abstract:
A robot apparatus is to be mounted on a robot hub, and includes a main robot link, a first robot extension arm, a second robot extension arm, a first robot blade, a second robot blade. A hub motor, a first extension motor, and a second extension motor. The main robot link is fixedly mounted to the robot hub. The first robot extension arm is rotatably mounted to a first end of the main robot link. The second robot extension arm is rotatably mounted to a second end of the main robot link. The first end of the main robot link is located on a distal end of the main robot link from the second end of the main robot link. The first robot blade is mounted to the first robot extension arm. The second robot blade is mounted to the second robot extension arm. The hub motor provides controllable rotational motion of the main robot link about the robot hub. The first extension motor is configured to provide controllable simultaneous extension or retraction of the first robot extension arm and the first robot blade. The second extension motor is configured to provide controllable simultaneous extension or retraction of the second robot extension arm and the second robot blade.

The present invention generally provides a robot that can transfer workpieces, such as silicon wafers, at increased speeds and accelerations and decelerations. More particularly, the present invention provides a robot wrist associated with the robot arm for mechanically clamping a workpiece to a workpiece handling member attached to the arm. The wafer clamp selectively applies sufficient force to hold the workpiece and prevent slippage and damage to the workpiece during rapid rotation and linear movement of the handling member. In a particular embodiment, a clamp for securing silicon wafers uses a flexure assembly to position and hold the wafer with minimal particle generation and wafer damage. The clamp is designed so that the wafers are normally clamped near full extension of the workpiece handling member to deliver or pick up a wafer. A particular embodiment uses a pneumatic cylinder to actuate the flexure assembly so that the flexure assembly moves outwardly and rearwardly away from the wafer when actuated at or near full extension of the workpiece handling member.
