    Abstract: A configurable cryogenic storage device has a freezer and a rack carrier positioned inside of the freezer. The freezer includes a bearing and a drive shaft though the freezer, the drive shaft being coupled to the rack carrier inside the freezer and adapted to be coupled to a motor assembly. The rack carrier rests on the bearing in a manual rotation configuration and hangs from the drive shaft when the motor is connected. Coupling the drive shaft to the motor assembly lifts the rack carrier and decouples the bearing and enables automated rotation of the rack carrier by the motor. The rack carrier includes rack-mounting features holding a plurality of sample storage racks. The sample storage racks hang from the rack carrier and the rack-mounting features precisely position the end of each sample storage rack.

    Abstract: A substrate transport apparatus comprising a drive section, a controller, an upper arm, forearm and substrate holder. A proximate end of the upper arm being rotatably mounted to the drive section at a shoulder joint. A proximate end of the forearm being rotatably mounted to a distal end of the upper arm at an elbow joint. The substrate holder being rotatably mounted to a distal end of the forearm at a wrist joint. The upper arm and the forearm being unequal in length from joint center to joint center. The substrate transport arm is adapted to transport substrate to and from at least two substrate holding areas with the drive section of the transport apparatus remaining in a fixed position relative to the holding areas. Each of the upper arm, forearm and substrate holder being independently rotatable with respect to each other.

    Abstract: A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators depending on the computed aggregate cooling demand of all of the cryogenic refrigerators. An appropriate supply of helium is distributed to each cryopump by sensing excess and sparse helium and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly. If the total refrigeration demand exceeds the total refrigeration supply, the refrigerant supply to some or all of the cryogenic refrigerators will be reduced accordingly so that detrimental or slowing effects are minimized based upon the current cooling function.
