  • Publication number: 20240186166
    Abstract: A system for holding and transporting one or more workpieces is disclosed. The system includes a cassette that is configured to support a carrier and a workpiece at two different elevations. In this way, as the carrier with the workpiece is placed on the cassette by a first robot, the carrier moves down further, as the workpiece is supported by taller support posts. The end effector of a second robot may then later remove only the workpiece from the cassette for processing. The processed workpiece is later placed back in the cassette by the second robot. This processed workpiece is then removed, along with the carrier, by the first robot. Carriers may be created to accommodate different sized workpieces such that the cassette remains unchanged.

  • Patent number: 11975422
    Abstract: Embodiments described herein provide for devices and methods for retaining optical devices. The devices and methods described herein provide for retention of the substrate without contacting sensitive portions of the substrate. The devices and methods utilize retention pads or vacuum pins to contact the exclusion zones i.e., inactive areas of the substrate to retain the substrate and prevent the substrate from moving laterally. Additionally, a holding force retains the substrate in the vertical direction, without contacting the substrate. The methods provide for adjusting the devices to account for multiple geometries of the substrate. The methods further provide for adjusting the devices, such as adjusting a gap between the optical device and a suction pad, to alter the holding force of the devices on the optical devices.

  • Publication number: 20230239970
    Abstract: A heater assembly that that is effective at maintaining heating lamps at acceptable temperatures is disclosed. The heater assembly utilizes radiative heat transfer to transfer unwanted heat buildup in the heating lamps to a cooling base. One or more high emissivity films are disposed between the heating lamps and the cooling base to facilitate heat transfer. Further, a reflective coating is applied to a portion of the heating lamps to reflect heat away from the cooling base. The heater assembly may be utilized in a high vacuum environment as it does not rely on convective cooling.

  • Patent number: 11545375
    Abstract: A system and method of heating a workpiece to a desired temperature is disclosed. This system and method consider the physical limitations of the temperature device, such as time lag, temperature offset, and calibration, in creating a hybrid approach that heats the workpiece more efficiently. First, the workpiece is heated using open loop control to heat the workpiece to a threshold temperature. After the threshold temperature is reach, a closed loop maintenance mode is utilized. In certain embodiments, an open loop maintenance mode is employed between the open loop warmup mode and the closed loop maintenance mode. Additionally, a method of calibrating a pyrometer using a contact thermocouple is also disclosed.
