摘要:
A substrate processing apparatus (10) comprising a frame (16), a drive section (42), an articulated arm (44), and at least one pair of end effectors (64, 66). The drive section (42) is connected to the frame (16). The articulated arm (44) is connected to the drive section (42). The articulated arm (44) has a shoulder (72) and a wrist. The arm (44) is pivotally mounted to the drive section (42) at the shoulder (72). The pair of end effectors (64, 66) is connected to the articulated arm (44). The pair of end effectors (64, 66) is pivotally jointed to the wrist of the articulated arm (44) to rotate relative to the articulated arm (44) about a common axis of rotation at the wrist. Each end effector (64, 66) is independently pivotable about the common axis of rotation of the wrist relative to the articulated arm (44).

The present invention provides an apparatus and associated method in which the apparatus comprises a multiple blade robot and a compensating device. The multiple blade robot includes at least one set of robot blades. The compensating device adjusts for differences in spacing between the set of robot blades and spacing between two or more cells. In different embodiments, the compensating device may be coupled to one or more of the process cells, one or more of the substrate holder systems, or one or more of the robot blades.

摘要:
A wafer processing system which requires no isolation between the operational areas within the processing system. The system of the present invention includes operational areas, such as a loading area, a transport area, and a reactor or thermal processing area. Advantageously, since there are no isolation devices or gate valves separating the areas, the processing system effectively has each operational area combined into a "single" chamber. Preferably, the single chamber has a single slit valve, hinge door, or other vacuum sealable door disposed proximate to the loading area to allow for the removal/insertion of the wafers into the loading area. Once the door to the loading area has been closed the internal pressure within the chamber can be kept uniform throughout each operational area.

A wafer processing system occupies minimal floor space by using vertically mounted modules such as reactors, load locks, and cooling stations. Further saving in floor space is achieved by using a loading station which employs rotational motion to move a wafer carrier into a load lock. The wafer processing system includes a robot having extension, rotational, and vertical motion for accessing vertically mounted modules. The robot is internally cooled and has a heat resistant end-effector, making the robot compatible with high temperature semiconductor processing.

A wafer handling robot (100) is disclosed for transporting workpieces. The robot includes a base (102) comprising a rigid backbone (112) for providing stability to the robot. The base further includes a mast (116), a linear drive system (122) for translating the mast, and a shoulder drive system (120) for rotating the mast. The shoulder drive system includes a harmonic drive reduction system (138) for providing output rotation of the mast for rotation with the mast, and a distal link (106) rotatably mounted to the proximal link. An end effector (108) for supporting workpieces is rotationally mounted to the distal end of the distal link. An elbow drive (150) is mounted to the proximal link, extending down into the mast section, for driving rotation of the distal link with respect to the proximal link.
摘要:
A magnetic drive system for moving a substrate transfer shuttle along a linear path between chambers in a semiconductor fabrication apparatus. A rack with rack magnets is secured to the shuttle, and a rotatable pinion with pinion magnets is positioned adjacent the rack so that the pinion magnets can magnetically engage the rack magnets. Thus, rotation of the pinion will cause the shuttle to move along the linear path. The magnets may be oriented with a helix angle between their primary axis and the axis of rotation of the pinion. One rack and one pinion are located on each side of the shuttle. A set of lower guide rollers supports the shuttle, and a set of upper guide rollers prevents the shuttle from lifting off the lower guide rollers.

The present invention provides a robot blade and a method of using the robot blade for transferring objects, namely substrates, through a process system, the robot blade comprising an upper platform having a first object supporting surface and a lower platform having a second object supporting surface. The robot blade is mounted onto a moveable member, and the assembly facilitates substrate transfers, such as removal of a processed substrate and insertion of an unprocessed substrate within a processing chamber through a single entry of the robot blade into the processing chamber.
摘要:
The present invention generally provides a robot that can transfer two workpieces, such as silicon wafers, simultaneously and 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 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.
