摘要:
Embodiments of the present invention relate to improvements to single-substrate, multi-chamber processing platform architecture for minimizing fabrication facility floor space requirements. Prior art systems require significant floor space around all sides to allow for adequate installation and servicing. Embodiments of the present invention provide platforms that allow for servicing the chambers and supporting systems via a front and rear of the platform allowing multiple, side-by-side platform placement within a fabrication facility, while providing improved serviceability of the platform components.

Embodiments of the invention generally contemplate an apparatus and method for monitoring and controlling the temperature of a substrate during processing. One embodiment of the apparatus and method takes advantage of an infrared camera to obtain the temperature profile of multiple regions or the entire surface of the substrate and a system controller to calculate and coordinate in real time an optimized strategy for reducing any possible temperature non-uniformity found on the substrate during processing.
摘要:
Methods and apparatus for measuring substrate uniformity is provided. The invention includes placing a substrate in a thermal processing chamber, rotating the substrate while the substrate is heated, measuring a temperature of the substrate at a plurality of radial locations as the substrate rotates, correlating each temperature measurement with a location on the substrate, and generating a temperature contour map for the substrate based on the correlated temperature measurements. Numerous other aspects are provided.
摘要:
Methods and apparatus for forming substrates having magnetically patterned surfaces is provided. A magnetic layer comprising one or more materials having magnetic properties is formed on the substrate. The magnetic layer is subjected to a patterning process in which selected portions of the surface of the magnetic layer are altered such that the altered portions have different magnetic properties from the non-altered portions without changing the topography of the substrate. A protective layer and a lubricant layer are deposited over the patterned magnetic layer. The patterning is accomplished through a number of alternative processes that expose substrates to energy of varying forms.

Aspects of the invention include methods and apparatus for processing a batch of substrates. In one embodiment, a compressed substrate boat is configured to reduce pumping volume in a batch processing chamber. The compressed substrate boat comprises a stationary substrate boat and a movable substrate boat, each may be loaded/unloaded independently. The movable substrate boat and the stationary substrate boat may be interleaving with one another such that the distance between the substrates is reduced. In another embodiment, a substrate boat having removable substrate holder is configured to provide susceptors without dramatically increasing pumping volume. The removable substrate holder may be loaded/unloaded away from the substrate boat with susceptors. The removable substrate holder is engaged with the substrate boat such that substrates thereon are interleaving with the susceptors. Embodiments of the present invention reduces pumping volume and increases throughput, hence reduces cost of ownership during batch processing.

Methods and apparatus for processing substrates are disclosed herein. The process chamber includes a chamber body, a substrate support pedestal, a pump port and a gas injection funnel. The chamber body has an inner volume and the substrate support pedestal is disposed in the inner volume of the chamber body. The pump port is coupled to the inner volume and is disposed off-center from a central axis of the substrate support pedestal. The pump port provides azimuthally non-uniform pumping proximate to a surface of the substrate support pedestal and creates localized regions of high pressure and low pressure within the inner volume during use. The gas injection funnel is disposed in a ceiling of the chamber body and opposite the substrate support pedestal. The gas injection funnel is offset from the central axis of the substrate support pedestal and is disposed in a region of low pressure.

摘要:
An apparatus and method for determining the state of a switch for use in an HVAC system. The apparatus and method are advantageously configured for use within a heating, ventilation and air conditioning (HVAC) system, in which the sensing of the state of safety switches external to a controller is desirable. A current sensor coupled in series between a current source, a safety switch, and a current load, detects the flow of current from the current source and through the switch and load. A status signal, indicative of the flow of current through the current sensor, is generated for sampling by a microprocessor. The presence or absence of current flow through the current sensor provides an indication as to whether the remotely-located switch is in an open or closed state.

A control system for a fluid-fuel burner, such as a furnace for an HVAC system. The furnace has a variable flow of fuel into the burner. In addition, the circulating air blower is also variable. The furnace heat exchanger plenum is maintained at a substantially constant temperature, as a means for providing substantially constant temperature air to the spaces to be heated.
