摘要:
A semiconductor inspection apparatus performs a hybrid inspection process including cell-to-cell inspection, die-to-die inspection and die-to-golden or die-to-database inspection. The apparatus creates a golden image of a reticle complimentary to portions of the reticle that can be inspected by cell-to-cell inspection or die-to-die inspection. Alternatively, the apparatus creates a reduced database complimentary to portions of the reticle that can be inspected by cell-to-cell inspection or die-to-die inspection.

A bed including a frame, an articulating deck on the frame having head, seat, and foot deck sections, and a mattress on the deck. The deck foot section and mattress foot portion have a first length when the foot section is in the up position and a second length shorter than said first length when the foot section is in the down position. A first driver varies the length of the deck foot section, and a second driver moves the foot section relative to said seat section between the generally horizontal up position and the generally vertically downwardly extending down position.
摘要:
A submicron filter assembly (24) is added to an exhaust gas controlled destruction and oxidation unit (10). Controlled destruction and oxidation unit (10) treats exhaust gas from at least one semiconductor wafer fabricating reactor. The submicron filter (24) filters submicron particles out of the treated exhaust gas to prevent visible plumes from forming in wafer fab exhaust systems (stacks). The controlled destruction and oxidation unit (10) and submicron filter assembly (24) are ideally suited for use at the point of generation of the exhaust gases. In one embodiment of the invention, the submicron filter assembly comprises an electrostatic filter (26). The electrostatic filter (26) includes a positively charged first grid (28) and a grounded second grid (30). The second grid may include a mist screen for removing particulate build-up. In another embodiment of the invention, the submicron filter assembly (36) comprises a mist eliminator (38) and a HEPA filter (40).
摘要:
A filter capable of being used in subterranean environments includes a filter medium. An erosion barrier is disposed along a common flow path with the filter medium for preventing erosion by particles in a fluid being filtered.
摘要:
A filter segment disc of a segment filter comprises a support and drainage plate with slots radiating from the filter hub toward the filter edge. The slots are preferably of arcuate plan form and configured to provide a substantially uniform fluid flow over the filtering medium of the filter segment, reduce residence time of filtrate in the filter, eliminate dead spots in the flow, and facilitate cleaning of permanent filters. A filter support spacer may be provided adjacent the filtering surface to aid in support and positive spacing of the disc in a filter stack of which the disc may be an element.
