摘要： A method for fabricating a photovoltaic (PV) cell panel wherein all PV cells are formed simultaneously on a two-dimensional array of monocrystalline silicon mother wafers affixed to a susceptor is disclosed. Porous silicon separation layers are anodized in the surfaces of the mother wafers. The porous film is then smoothed to form a suitable surface for epitaxial film growth. An epitaxial reactor is used to grow n- and p-type films forming the PV cell structures. Contacts to the n- and p-layers are deposited, followed by gluing of a glass layer to the PV cell array. The porous silicon film is then separated by exfoliation in a peeling motion across all the cells attached together above, followed by attaching a strengthening layer on the PV cell array. The array of mother wafers may be reused multiple times, thereby reducing materials costs for the completed solar panels.

摘要： A system for depositing thin single crystal silicon wafers by epitaxial deposition in a silicon precursor depletion mode with cross-flow deposition may include: a substrate carrier with low total heat capacity, high emissivity and small volume; a lamp module with rapid heat-up, efficient heat production, and spatial control over heating; and a manifold designed for cross-flow processing. Furthermore, the substrate carrier may include heat reflectors to control heat loss from the edges of the carrier and/or heat chokes to thermally isolate the carrier from the manifolds, allowing independent temperature control of the manifolds. The carrier and substrates may be configured for deposition on both sides of the substrates—the substrates having release layers on both sides and the carriers being configured to have equal process gas flow over both surfaces of the substrate. High volume may be addressed by a deposition system comprising multiple mini-batch reactors.

摘要： An epitaxial reactor enabling simultaneous deposition of thin films on a multiplicity of wafers is disclosed. During deposition, a number of wafers are contained within a wafer sleeve comprising a number of wafer carrier plates spaced closely apart to minimize the process volume. Process gases flow preferentially into the interior volume of the wafer sleeve, which is heated by one or more lamp modules. Purge gases flow outside the wafer sleeve within a reactor chamber to minimize deposition on the walls of the chamber. In addition, sequencing of the illumination of the individual lamps in the lamp module may further improve the linearity of variation in deposition rates within the wafer sleeve. To improve uniformity, the direction of process gas flow may be varied in a cross-flow configuration. Combining lamp sequencing with cross-flow processing in a multiple reactor system enables high throughput deposition with good film uniformities and efficient use of process gases.

摘要： A dual wafer processing apparatus (4) includes a chamber housing (14) defining an interior and having upper, lower and central portions (18, 20, 16). An electrostatic chuck (34) has electrostatic chucking surfaces (38, 40) on opposite sides. The chuck is rotatably mounted within the chamber housing so that the chucking surfaces face the upper and lower portions of the chamber housing. After a wafer (36) is positioned on a chucking surface, electrostatic forces are used to maintain the wafer secured to the chucking surface. The chuck is then rotated 180.degree. to permit placement of a second wafer on the second chucking surface. Processing of the two wafers occurs simultaneously. Electrostatic chucking surfaces could be replaced by mechanical wafer clamps.
