摘要: A wafer carrier/susceptor combination for use in an epitaxial deposition process has a configuration which provides greater thermal conductivity between the susceptor and the wafer carrier in regions substantially underlying the wafers than in regions not underlying the wafers. This difference in thermal conductivity is produced by configuring the wafer carrier or susceptor so that the lower surface of the wafer carrier is disposed closer to the susceptor in regions substantially underlying the wafers than in at least some regions not underlying the wafers. By controlling the thermal conductivity so that it is greater in certain regions than in other regions, the temperature difference between the wafers and the surface of the wafer carrier can be reduced, and a more uniform temperature distribution across the surface of the wafer can be achieved. As a result, the combination may be used to deposit a more uniform coating across the entire surface of each wafer.

摘要: A method for characterizing a surface comprises rotating a carrier about an axis of rotation where the carrier has a top surface adapted to hold at least one semiconductor wafer with a major surface of the wafer extending generally transverse to the axis of rotation. A surface characterization tool is moved over a plurality of positions relative to the top surface of the carrier, where a measurement location over the top surface of the carrier is changed while said top surface of the carrier is heated to a predetermined temperature. Characterization signals over the plurality of positions with the surface characterization tool are produced and contain information about the heated top surface of the carrier, or when semiconductor wafers are held on the carrier, information about the semiconductor wafer can also be obtained.

摘要: A wafer carrier for use in a system for growing epitaxial layers on one or more wafers by chemical vapor deposition. The wafer carrier includes wafer retention pockets recessed in its body. Each pocket includes a floor surface and a peripheral wall surface surrounding the floor surface and defining a periphery of that pocket. Each pocket has a center situated along a corresponding wafer carrier radial axis. In each of the pockets, a set of bumpers is positioned primarily at a distal portion of the wafer retention pocket opposite the central axis so as to maintain a gap of at least a predefined size between the peripheral wall surface at the distal portion and an edge of a wafer to be placed in the wafer retention pocket.

摘要: A method for determining the temperature of a surface upon which a coating is grown using optical pyrometry by correcting Kirchhoff's law for errors in the emissivity or reflectance measurements associated with the growth of the coating and subsequent changes in the surface thermal emission and heat transfer characteristics. By a calibration process that can be carried out in situ in the chamber where the coating process occurs, an error calibration parameter can be determined that allows more precise determination of the temperature of the surface using optical pyrometry systems. The calibration process needs only to be carried out when the physical characteristics of the coating chamber change.
