Abstract:
One embodiment of this ion implanter (100) includes an ion source (101) and a process chamber (102). This process chamber is connect- ed to the ion source and separated from the ion source by a plurali- ty of extraction electrodes (114). A carrier (201) holds multiple work- pieces (202). A mask loader (205) in the process chamber connects a mask (203) to the carrier. A transfer chamber (104) and load lock (105, 106) may be connected to the process chamber. The ion im- planter is configured to perform blanket and/or selective implantation of the workpieces.
Abstract:
A vacuum assembly used for warming processed substrates above the dew point to prevent unwanted moisture on the processed substrate surfaces as well as reducing negative impact on manufacturing throughput The vacuum assembly includes a processing chamber, a substrate handling robot, and a heater which may be an optical heater. The processing chamber is configured to cryogenically process one or more substrates. The transfer chamber is connected to the processing chamber and houses the substrate handling robot. The substrate handling robot is configured to displace one or more substrates from the processing chamber to the transfer chamber. The heater is connected to the transfer chamber above the substrate handling robot such that the heater emits energy incident on the substrate when the substrate handling robot displaces the substrate in the transfer chamber.
Abstract:
A coating apparatus comprises a coating chamber for coating the articles. The at least one preheat chamber is coupled to the coating chamber. The at least one loading station has a proximal end connectable to at least one of the preheat chambers when in an installed position at a distal end of the preheat chamber. The loading station further includes a carrier for carrying the articles and a drive system. The drive system is positioned to move the carrier between: a loading/unloading position of the carrier in the loading station; a preheat position of the carrier in the preheat chamber to which the loading station is connected; and a deposition position of the carrier in the coating chamber. A gas source is connected to the preheat chamber.
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:
Wafer-holding structures formed from thermosetting resins are disclosed for use in semiconductor processing including, for example, SIMOX wafer processing. In one embodiment a thermosetting resin pin is disclosed that is adapted to receive a wafer edge, and is coupled with a wafer holder assembly. The pin can be filled with a conductive material to provide an electrical pathway between the wafer and the wafer holder assembly, which can be coupled to a ground. This arrangement provides a conductive path for inhibiting electrical discharges from the wafer during the ion implantation process. The pin exhibits thermal isolation characteristics and sufficient hardness so as to not effect localized thermal dissipation of the wafer, yet is sufficiently soft so as to not mark or otherwise damage the wafer. At least a portion of the distal portion of the pin comprises graphite, thereby reducing wafer- rotation during ion implantation while maintaining the desired overall thermal signature provided by the thermosetting resin.

Abstract:
A technique for low-temperature ion implantation is disclosed. In one particular exemplary embodiment, the technique may be realized as an apparatus for low-temperature ion implantation. The apparatus may comprise a pre-chill station located in proximity to an end station in an ion implanter. The apparatus may also comprise a cooling mechanism within the pre-chill station. The apparatus may further comprise a loading assembly coupled to the pre-chill station and the end station. The apparatus may additionally comprise a controller in communication with the loading assembly and the cooling mechanism to coordinate loading a wafer into the pre-chill station, cooling the wafer down to a predetermined temperature range, and loading the cooled wafer into the end station where the cooled wafer undergoes an ion implantation process.
Abstract:
A transfer system for use with a tool for treating a work-piece at sub-atmospheric pressure such as an ion implanter for implanting silicon wafers. An enclosure defines a low pressure region for treatment of work-pieces placed at a work-piece treatment station within the low pressure region. Multiple work-piece isolation load locks transfer work-pieces, one or two at a time, from a higher pressure region to the lower pressure for treatment and back to said higher pressure subsequent to said treatment. A first robot transfers work-pieces within the low pressure region from the load locks to a treatment station within the low pressure region. Multiple other robots positioned outside the low pressure region transfers work-pieces to and from the multiple work-piece isolation load locks from a source of said work-pieces prior to treatment and to a destination of said work-pieces after said treatment.
Abstract:
A structure, in which a second treating unit group that performs, under vacuum or pressure, e.g., an electron beam or ultraviolet ray irradiation, a CVD or a cleaning treatment is provided integrally with a first treating unit group that forms an interlayer insulation film under a normal pressure, can shorten a treating time especially in a damascene process to decrease foot print per treating power. A treating time thus shortened can prevent an insulating film from absorbing moisture in the air that causes deterioration in film quality, and contribute to forming a quality insulation film even if a porous film, for example, is used as an insulation film.
Abstract:
A processing apparatus (13) for a semiconductor device comprises a casting section (13-1), a treatment section, and a delivery section (13-2). The casting section (13-1) receives the casting of a transport box which holds a semiconductor substrate. The treatment section takes in a semiconductor substrate cast into the casting section (13-1) and treats the semiconductor substrate. The delivery section (13-2) is disposed unlevel with the casting section (13-1) and delivers a transport box which holds a semiconductor substrate exhausted from the semiconductor substrate treatment section.
