摘要: A wafer carrier used in wafer treatments such as chemical vapor deposition has pockets for holding the wafers and support surfaces for supporting the wafers above the floors of the pockets. The carrier is provided with locks for restraining wafers against upward movement away from the support surfaces. Constraining the wafers against upward movement limits the effect of wafer distortion on the spacing between the wafer and the floor surfaces, and thus limits the effects of wafer distortion on heat transfer. The carrier may include a main portion and minor portions having higher thermal conductivity than the main portion, the minor portions being disposed below the pockets.

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 wafer carrier for use in a chemical vapor deposition apparatus includes at least one region on its outer surface having a substantially different (e.g., lower) emissivity than other regions on the outer surface. The modified emissivity region may be located on the outer edge, the top surface, and/or the bottom surface of the carrier. The region may be associated with one or more wafer pockets of the wafer carrier. The modified emissivity region may be shaped and sized so as to modify the heat transmission through the region, and thereby increase the temperature uniformity across portions of the top surface of the wafer carrier or across individual wafers. The modified emissivity region may be provided by a coating on the outer surface of the wafer carrier.
