Abstract: There is provided a chuck that includes a supporting element that is connected to a closing element. An upper surface of the supporting element includes a chemically etched zone and an un-etched zone. The chemically etched zone includes multiple upper areas that are surrounded by trenches. At least one pressurized gas conduit is formed in the supporting element so as to enable pressurized gas provided to a lower surface of the supporting element to propagate through the trenches. The un-etched zone is shaped in response to a shape of an object to be placed on the supporting element. The un-etched zone reduces pressurized gas leakage from the un-etched zone and the closing element reduces pressurized gas leakage from a lower surface of the supporting element when the object is placed on the chuck in alignment with the un-etched zone and pressurized gas is provided to the chuck.

Abstract: A system that may include a printing module arranged to print patterns on a substrate by inkjetting ink on the substrate; and a substrate supporting module that comprises: a porous material module for supporting the substrate and providing vacuum to multiple locations of the substrate when the substrate is placed on a flat upper surface of the porous material module; and an interface module that comprises: at least one inlet for receiving vacuum from a vacuum system; at least one outlet for providing the vacuum to the porous material module; and at least one structural element arranged to contact the porous material module and provide mechanical support to the porous material module.

Abstract: A system includes a first supporting element, a first supporting element rotation module, a controller and a first optical head. The controller is configured to control a rotation of the first supporting element by the first supporting element rotation module. The first supporting element is coupled to the first optical head. The first supporting element rotation module is configured to rotate the first supporting element until text that is imprinted on a first side of a semiconductor wafer is located within a field of view of the first optical head. Semiconductors wafers of different size have text located at different locations.

Abstract: A diced wafer adaptor that includes: a cylindrical shaped inner portion, adapted to support and hold an annular frame and a membrane suspended within the annular frame and to apply vacuum to an outer portion of the membrane; wherein an inner portion of the membrane supports a diced wafer and is surrounded by the outer portion of the membrane; and an outer portion having a perimeter shaped substantially as a perimeter of a non-diced wafer.

Abstract: An optical communication link coupling a rotating part of a gantry of a computerized tomographic scanner to the stationary part of the gantry. The link comprises an arcuate hollow light conductor having one part rotating with the rotor of the gantry and the other part fixed to the stator of the gantry. Signal bearing light beams are transmitted into the link and are subsequently received from the link after transversing at least a portion theroef.
