Methods and apparatus for providing constant emissivity of the backside of susceptors are provided. Provided is a susceptor comprising: a susceptor plate having a surface for supporting a wafer and a backside surface opposite the wafer supporting surface; a layer comprising an oxide, a nitride, an oxynitride, or combinations thereof located on the backside surface of the susceptor plate, the layer being stable in the presence of a reactive process gas. The layer comprises, for example, silicon dioxide, silicon nitride, silicon oxynitride, or combinations thereof. Also provided is a method comprising: providing a susceptor in a deposition chamber, the susceptor comprising a susceptor plate and a layer comprising an oxide, a nitride, an oxynitride, or combinations thereof, the layer being stable in the presence of the reactive process gases; locating the wafer on a support surface of the susceptor plate. The method can further comprises selectively depositing an epitaxial layer or a non-epitaxial layer on a surface of the wafer. The method further comprises selectively etching to maintain the oxide, nitride, oxynitride, or combinations thereof layer.

A halogen lamp assembly 20 for a substrate processing chamber 100 has a halogen lamp 22 and a ceramic heat sink monolith 24. The halogen lamp 22 includes a filament 28 and a pair of electrical connectors 30 encapsulated in an envelope 26 having a pinch seal end 34. The ceramic heat sink monolith 24 includes a block 38 and an array of spaced apart posts 40 projecting outwardly from the block 38. The block 38 includes a cavity 42 that has a recessed inner surface 44 shaped to mate with the pinch seal end 34 of the lamp 22 and an opening that allows the electrical connectors 30 of the halogen lamp 22 to pass through.

摘要:
A tantala ring resonator includes a tantala ring resonator formed by ion-beam sputtering of tantalum pentoxide and exhibiting an optical quality factor in excess of 3×106, and a substrate to which the tantala ring resonator is attached. A method for fabricating nonlinear photonic devices includes depositing tantalum pentoxide with ion-beam sputtering to form a tantala layer onto a substrate, annealing the tantala layer, and etching the tantala layer to form a photonic device.

A method for developing cost-effective pathways for treatment using an evidence-based approach may include enabling suggestions of imperfect times for cyclical appointments may include receiving availability information defining available periods for a healthcare related asset, receiving appointment parameters defining a number and frequency of recurring appointments to be scheduled, determining, via processing circuitry, periods of overlap between the available periods and the appointment parameters, and determining an inconsistent schedule pattern based on the periods of overlap. A corresponding computer program product and apparatus are also provided.
摘要:
A system that allows the remote measurement of the size, geometry, pitch and orientation of the roof sections of a building and then uses the information to provide an estimate to repair or replace the roof, or to install equipment thereon. The system includes an aerial image file database that shows aerial images of buildings in a designated area according to address. The slope and orientation images are typically oblique perspective views and top plan views of the buildings in the area. The system also includes an image analysis and calibration feature that enables the viewer to closely estimate the size, geometry and orientation of the building's roof sections. The information can then be used to prepare a cost estimate for the repair or replacement of the roof or installation of roof equipment. By simply inputting the potential customer's address, the company is able to determine the size, geometry, pitch and orientation of the roof sections of the building at that address, and then quickly provide an accurate estimate to the customer.

Systems and methods are disclosed that include adjusting a pressure level of a sample gas in a testing chamber, for example, using a pressurized inert reference gas, and determining a composition of the adjusted sample gas. By adjusting the pressure level of the sample gas, the composition of the sample gas may be determined more accurately than otherwise possible. Numerous other aspects are disclosed.
