摘要： The presently described embodiments are directed to a calibration method and system for thin film thermistors that are locally heated with integrated thin film heaters. Initially, print head temperature is either measured or referenced. Then, transient thermistor resistances are measured and used to determine the thermistor resistance at a higher temperature. Notably, this calibration method is advantageously implemented as a step of an existing process without having to expose the print heads to operating temperatures. In some implementations of the presently described embodiments, trimming of the thermistors may be required once calibrated.

摘要： This invention provides a method and apparatus for substantially eliminating deposition on the edge of a wafer supported on a pedestal in a processing chamber. Process gas flow onto the wafer surface is inhibited from reaching the wafer edge and backside, by means of a shadow ring placed over the wafer without touching it. Deposition on the edge and backside of the wafer are therefore substantially eliminated. The shadow ring defines a cavity which circumscribes the wafer edge, into which purge gas is flowed. This purge gas flows out from the cavity through the gap between the shadow ring and the upper surface of the wafer. Alignment pins are placed on the wafer supporting surface of the pedestal. These pins have sloping surfaces and are arranged to guide the wafer to a centered position on the pedestal when the wafer is placed on the pedestal. These pins also serve to align the shadow ring to the pedestal and thence to the wafer. The shadow ring has a plurality of keyed formations which mate to the pins, and as the shadow ring and pedestal are brought together, the pins serve to align the shadow ring. This precise rotational alignment and centering of the shadow ring results in substantial elimination of edge deposition. The keyed formations have elliptical cross-sections to provide for radial movement of the pins with respect to the keyed formations due to thermal expansion.

摘要： Vacuum CVD chambers are disclosed which provide a more uniformly deposited thin film on a substrate. The chamber susceptor mount for the substrate is heated resistively with a single coil firmly contacting the metal of the susceptor on all sides, providing uniform temperatures across the susceptor mount for a substrate. A purge gas line is connected to openings in the susceptor outside of the periphery of the substrate to prevent edge and backside contamination of the substrate. A vacuum feed line mounts the substrate to the susceptor plate during processing. A refractory purge guide, or a plurality of placement pins, maintain a fixed gap passage for the purge gases to pass alongside the edge of the wafer and into the processing area of the chamber. An exhaust pumping plate improves the uniformity of exhaustion of spent gases from the chamber.
