  • Patent number: 9051649
    Abstract: Provided is a physical vapor deposition apparatus with one or multiple deposition chambers for depositing films on substrates. The deposition chambers includes a heater and various cooling features to cool the chamber, the heater and the substrate. The sidewalls and top of the chamber are cooled by a cooling feature. The heater includes a cooling plate. A fitted heated cover is disposed between the heater and the substrate. A cooling pipe delivers a coolant throughout the cooling plate and extends in a high spatial density throughout the surface of the cooling plate. The cooling pipe occupies an area of about 14-20% of the area of the cooling plate and no location on the cooling plate surface is greater than about 15-20 mm from the cooling pipe. The cooling pipe cools the heater rapidly and enables deposition operations of long duration and using high power to be carried out.
