摘要:
A substrate processing apparatus having a station (140) for loading and unloading substrates from the apparatus, includes an aperture closure for sealing a loading and unloading aperture of the station (140), apparatus (230, 235) for removing a door of a substrate magazine and thus opening the substrate magazine, and for operating the aperture closure to open the aperture, and an elevator (215) for precisely positioning the open substrate magazine along a vertical axis within a usable range of motion. The station (140) may also include a sensor (245) for mapping locations of the substrates, and a mini-environment for interfacing the station to a substrate processing system.
摘要:
A method and apparatus for insulating and controlling temperature in a semiconductor manufacturing environment. The invention comprises at least one modular heater element designed to be mounted about a semiconductor furnace process chamber in order to minimize thermal transfer between the furnace interior and exterior. A base ring or cylinder (200, 500, 700) also referred to as a heater ring is sized to be fitted around an inner skin of a semiconductor mini-batch furnace. The base ring (200, 500, 700) has multiple channels (220, 520) equidistantly spaced about its inner perimeter. Heating coils of a type well known in the art may nest in these channels in order to warm the furnace interior. The coils may be either removably or permanently affixed within the channels.

The invention relates generally to equipment for semiconductor wafer processing, for example, mechanisms and apparatus for handlig pods or containers for housing silicon wafers or substrates. The pod may be a front-opening unified pod or similar article and may house a carrier or cassette for holding the wafers or substrates. Additionally, the invention relates generally to an automated system for transporting a plurality of wafers in the pod for processing, loading the pod on the receiving station, sealig the pod against an interface, openeing the door of the pod, and shuttling the wafers into and out of a connected clean environment processing station, such as an ion implantation machine, using a robotic device.

An automated door removal and replacement system (98) utilizes a combination of linear and rotational drive to remove a door (116) of a wafer supporting device (12) and store the door below the device. In one embodiment, the wafer-supporting device is a Front Opening Unified Pod (FOUP). A door-contacting assembly (114) is pivotally mounted to include a horizontal rest position and a vertical unlocking position. In the horizontal rest position, the assembly resides below the wafer-supporting device. The assembly is rotated to a vertical position and then linearly moved to engage the door. Keys (88, 90, 94 and 96) of the assembly are manipulated to release the door. The assembly and the door are moved rearwardly and the assembly is pivoted to the rest position, clearing the opening to the wafer-supporting device.

There are provided a container base (104) on which a holder container (106) having an openable/closable door (108) and capable of housing a wafer holder (68) in a sealed state, an opening/closing mechanism (112) for opening/closing the door (108) in a state where the inside of the container (106) placed on the container base (104) is isolated from the outside, and a transfer system (100) for exchanging the holder on a stage (WST) for the holder in the container (106). The transfer system (100) can exchange holders in a short time in a state where the inside of the system is isolated from the outside, so that the system stop time is as short as possible and that the cleanliness of the holders can be always maintained high. As a result, the productivity of devices such as semiconductor devices is improved.
摘要:
A semiconductor wafer batchloading system comprises a portable carrier (32) for supporting and transporting wafers in a substantially particle free environment. A carrier door (42) is movable between an open position and a closed position overlying a carrier port (38) for sealing the interior of the carrier (32) from the surrounding environment. The carrier (32) is movable on a platform (60) between withdrawn and advanced positions for delivering multiple wafers to a wafer receiving station. The carrier door drive mechanism includes a generally planar door opener (102) movable between a lowered position and a raised position substantially coextensive with the carrier port. (38).
摘要:
A system is disclosed for retaining a pod door (22) on a port door (26) at a load port, and for removing contaminants, particulates and/or gasses from between the pod and port door (26) surfaces and from within the interior of the pod door (22). According to a preferred embodiment of the present invention, a vacuum source (36) may be provided within, adjacent to, or remote from a process tool, which vacuum source (36) is connected to a vacuum port (34) in the front surface of a port door (26). The vacuum is provided to produce a negative pressure between juxtaposed surfaces of the port (26) and pod (22) doors.
摘要:
A system is described herein including a load port (24) which allows various pod (32) sizes, including 200 mm and 300 mm, and various configurations, including front opening and bottom opening, to operate with a BOLTS interface (22), or simply with a vertical port on the front end of a process tool in configurations not including the BOLTS interface (22).
