Title: Flexible rotary mesh filter
Inventor: BAUGHAN ANDREW
IPC: B03B5/56
Filed: 2009-02-02
Abstract: Disclosed is an elastic or flexible rotary mesh filter 3. A number of such filters 3 may be attached to a rotatable frame 2. Upon rotation of the frame 2, a semi rigid member or flapper 7 may press against the filters 3 causing them to flex. This may cause apertures in the filters 3 to enlarge, urging debris stuck in the filters 3 to fall back into the centre of the rotatable frame 3. The flexibility of the filter panels 3 may thus permit self cleaning function in a rotary separator. The weight of material being processed may cause enough flexing in the filters to provide the self cleaning function, without the need to use a flapper 7. The arrangement may be of particular use in cleaning a rotary filter processing mixed wet and dry materials.

IPC: H01L21/683
Filed: 2009-04-03
Abstract: A method and apparatus for retaining or clamping a substrate 22, such as a wafer, on a surface of a substrate support structure 23 uses a liquid 64 applied to the support surface that comprises a plurality of contact elements 27. The liquid 64 is first applied to fully cover the elements (figs 7a-c) and trapped gas (62) may be allowed to escape. Then the substrate is placed onto the liquid layer (7d-e). Finally, some of the liquid 64 is withdrawn 65,67 so that the substrate rests on the plurality of contact elements and is held by means of a capillary clamping force exerted by the thin liquid layer. The wafer may be released by adding more liquid to the layer to cause the wafer to float above the contacts 27. Figures 11 a-d shows a mechanism for lowering the wafer at angle alpha, preferably between 5 and 10 degrees, between the liquid and wafer. The liquid may be water.
