20080304940 | Integrated post-exposure bake track - Systems and methods for processing wafers, a combined post expose bake and chill unit, and an interface are disclosed. An exemplary system includes a lithography tool, local track, transfer device, transfer device handler, interface unit, and controller to schedule processing. An exemplary combined post expose bake and chill unit includes an enclosure having an opening in its side, and a bake unit and a chill unit in the enclosure. An exemplary interface includes a plurality of enclosures arranged around robot(s) that transfer wafers among the enclosures, one of the plurality of enclosures being an integrated bake and chill unit. | 12-11-2008 |

20100002207 | LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD - A lithographic apparatus includes a projection system configured to project an image onto a substrate, a substrate table configured to support the substrate, a first chamber that at least partially surrounds the projection system, and a second chamber that at least partially surrounds the substrate table and a first frame. The apparatus includes a base frame configured to support the second chamber, and an intermediate frame coupled to the base frame. The intermediate frame is configured to separate the first chamber and the second chamber. The apparatus includes a support coupled to the first frame. The support is configured to support the first chamber through a coupled opening in the intermediate frame and the second chamber. | 01-07-2010 |

20090061361 | Integrated Circuit Manufacturing Methods with Patterning Device Position Determination - Methods of manufacturing an integrated circuit by a lithographic apparatus are disclosed. The methods include patterning a radiation beam with a patterning device, projecting the patterned beam onto a substrate using a projection system, and determining the position of the patterning device. In one example, the patterning device's position relative to the projection system is determined by measuring the position of the patterning device's support structure. In another example, the position can be determined by measuring a position of the patterning device relative to its support and by measuring a position of the support. In another example, a Z-position of the patterning device is determined by directing at least one beam of radiation onto a part of the patterning device located outside a pattern area. This can be done by directing a pair of laser beams from sensors on the projection system to reflecting strips on the patterning device. | 03-05-2009 |
