Abstract:
An apparatus for supercritical processing and non-supercritical processing of a workpiece comprises a transfer module, a supercritical processing module, a non-supercritical processing module, and a robot. The transfer module includes an entrance. The supercritical processing module, and the non-supercritical processing module are coupled to the transfer module. The robot is preferably located within the transfer module. In operation, the robot transfers a workpiece from the entrance of the transfer module to the supercritical processing module. After supercritical processing, the robot then transfers workpiece from the supercritical processing module to the non-supercritical processing module. After the non-supercritical processing, the robot returns the workpiece to the entrance of the transfer module. Alternatively, the non-supercritical processing is performed before the supercritical processing.
Abstract:
An electrostatic chuck and gripping system are configured for clamping and processing workpieces having differing diameters. An ion implantation apparatus selectively provides ions to a first workpiece and a second workpiece in a process chamber, where a diameter of the first workpiece is greater the second workpiece. A chuck supports the respective first or second workpiece within the process chamber during exposure to the ions. A load lock chamber isolates a process environment from an external environment and has a workpiece support for the respective first or second workpiece during a transfer of the first or second workpiece between the process chamber and the external environment. A vacuum robot transfers the first or second workpiece between the chuck and workpiece support, and has a gripper mechanism configured to selectively grip the first or second workpiece between a plurality of stepped guides.
Abstract:
Compositions, methods, and apparatus are described for carrying out nitrogen ion implantation, which avoid the incidence of severe glitching when the nitrogen ion implantation is followed by another ion implantation operation susceptible to glitching, e.g., implantation of arsenic and/or phosphorus ionic species. The nitrogen ion implantation operation is advantageously conducted with a nitrogen ion implantation composition introduced to or formed in the ion source chamber of the ion implantation system, wherein the nitrogen ion implantation composition includes nitrogen (N 2 ) dopant gas and a glitching-suppressing gas including one or more selected from the group consisting of NF 3 , N 2 F 4 , F 2 , SiF4, WF 6 , PF 3 , PF 5 , AsF 3 , AsF 5 , CF 4 and other fluorinated hydrocarbons of C x F y (x≥1, y≥1) general formula, SF 6 , HF, COF 2 , OF 2 , BF 3 , B 2 F 4 , GeF 4 , XeF 2 , O 2 , N 2 O, NO, NO 2 , N 2 O 4 , and O 3 , and optionally hydrogen-containing gas, e.g., hydrogen-containing gas including one or more selected from the group consisting of H 2 , NH 3 , N 2 H 4 , B 2 H 6 , AsH 3 , PH 3 , SiH 4 , Si 2 H 6 , H 2 S, H 2 Se, CH 4 and other hydrocarbons of C x H y (x≥1, y≥1) general formula and GeH 4 .
Abstract:
In one embodiment, a system for exfoliating a crystalline lamina from an implanted crystalline donor substrate comprises substrate supports attached to a transporting structure, where the supports are configured to support an implanted crystalline donor substrate by a vacuum (e.g., with an implanted surface in contact with the vacuum). The transporting structure is configured to sequentially transport the substrate supports from a loading station, through one or more heating modules and a cleaving module (where the crystalline lamina is thermally cleaved from the implanted crystalline donor substrate along a cleave plane while the lamina remains in contact with the vacuum), and then to an unloading station.
Abstract:
One embodiment of this workpiece handling system has conveyor belts and a load lock. A first swap robot holds and transports workpieces between a build station and the load lock. A gantry robot transports the workpieces between each of the conveyor belts and the first swap robot. In one instance, processed workpieces are transported from the first swap robot to a first conveyor belt and unprocessed workpieces are transported from a second conveyor belt to the first swap robot using the gantry robot. A second swap robot also may be used with the first swap robot to load and unload workpieces from the load lock.

Abstract:
The present invention relates to the use of a particle accelerator beam to form thin films of material from a bulk substrate. In particular embodiments, a bulk substrate having a top surface is exposed to a beam of accelerated particles. Then, a thin film of material is separated from the bulk substrate by performing a controlled cleaving process along a cleave region formed by particles implanted from the beam. To improve uniformity of depth of implantation, channeling effects are reduced by multiple techniques. In one technique, a miscut bulk substrate is subjected to the implantation, such that the lattice of the substrate is offset at an angle relative to the impinging beam In another technique, the substrate is tilted at an angle relative to the impinging beam. In another technique, the substrate is subjected to a ditheπng motion dunng the implantation. These techniques may be employed alone or in combination
Abstract:
The present invention generally provides a batch substrate processing system, or cluster tool, for in-situ processing of a film stack used to form regions of a solar cell device. In one configuration, the film stack formed on each of the substrates in the batch contains one or more silicon-containing layers and one or more metal layers that are deposited and further processed within the various chambers contained in the substrate processing system. In one embodiment, a batch of solar cell substrates is simultaneously transferred in a vacuum or inert environment to prevent contamination from affecting the solar cell formation process.

Abstract:
Techniques for low- temperature ion implantation are disclosed. In one particular exemplary embodiment, the techniques may be realized as a wafer support assembly (300) for low- temperature ion implantation. The wafer support assembly (300) may comprise a base (32). The wafer support assembly (300) may also comprise a platen (30) configured to mount to the base (32) via one or more low- thermal-contact members (312), wherein the platen (30) has a heat capacity larger than that of a wafer mounted thereon, such that, if pre-conditioned to a predetermined temperature, the platen (30) causes the wafer temperature to stay within a range of the predetermined temperature during ion implantation.
