A method comprises: heating a flow of coolant liquid by passing the flow through one or more fluidic tubing lines, channels or conduits that are in thermal contact with a housing of a vacuum pump; apportioning the flow of heated coolant liquid between a bypass fluid tubing line and a channel within a wall of a vacuum chamber; recombining the first and second partial flows of the heated coolant liquid; passing the recombined flow of the coolant liquid through a heat exchanger that cools the coolant liquid; and recirculating the cooled coolant liquid through the one or more fluidic tubing lines, channels or conduits that are in thermal contact with the vacuum pump housing, wherein the apportionment of the flow of the heated coolant liquid is automatically performed under the control of an electronic controller or computer in response to a temperature measurement received by the electronic controller or computer.

Methods and systems for cooling a vacuum pump

A system comprises: a vacuum chamber disposed within a housing and having a vacuum port; a vacuum pump within the housing and having a gas inlet port that is fluidically coupled to the vacuum port; and a fluid circuit that comprises: one or more fluidic tubing lines, channels or conduits in thermal contact with a housing of the vacuum pump; a liquid pump fluidically coupled to an inlet of the one or more fluidic tubing lines, channels or conduits; and a heat exchanger having a heat exchanger inlet and a heat exchanger outlet, wherein the heat exchanger inlet is fluidically coupled to an outlet of the one or more fluidic tubing lines, channels or conduits and the heat exchanger outlet is fluidically coupled to the liquid pump. The fluid circuit may also include a portion that is in thermal contact with the vacuum chamber.

A system for loading workpieces into a process chamber for processing in a matrix configuration includes a conveyor configured to transport multiple workpieces in a linear fashion. A workpiece hotel is configured to receive the multiple workpieces from the conveyor. The workpiece hotel comprises a matrix of cells arranged in N columns and M floors. A pick blade is configured to insert into the hotel and retract from the hotel in order to unload a plurality of substrates from a first floor into a single row of the pick blade, and to repeat the unloading operation to form a matrix comprising a plurality of rows of substrates disposed on the pick blade. In one example, the workpiece hotel has a staggered configuration that provides individual accessibility of each hotel cell.
