450mm Vacuum Heater Chuck

450mm - Vacuum Heater Chuck

An atomic layer deposition (ALD) application up to 450°C is the focus of the latest BCE 450mm vacuum heater chuck. The design is a compressed assembly with many vacuum holes and grooves in the bottom plate to allow the gases to escape during the pump down of the vacuum chamber. No surface anodizing is required.

This highly effective vacuum heater reached an atmospheric temperature of 450°C in under 45 minutes (700°C in Stainless). The reduced mass on the bottom plate provides proper gas elimination with a quicker initial ramp time. Due to this decreased ramp time, a reduced wattage may be an option for the future iterations of the 450mm Vacuum Heater Chuck.
