    摘要: A lithographic apparatus comprises an illumination system, an array of individually controllable elements, a projection system, a substrate table, and a sensor system. The illumination system supplies a beam of radiation. The array of individually controllable elements patterns the beam. The projection system projects the patterned beam onto a target plane, the patterned beam comprising an array of radiation spots. The substrate table supports a substrate, such that a target surface of the substrate is substantially coincident with the target plane. The sensor system comprises an array of detector elements arranged to receive at least one of the spots. The sensor system measures an energy of the or each received spot and provides an output signal indicative of the energy of the or each received spot.

    摘要: A lithographic projection apparatus is provided with an optical system built into the wafer table for producing an image of a wafer mark that is provided on the back side of the wafer. The image is located at the plane of the front side of the wafer and can be viewed by an alignment system from the front side of the wafer. Simultaneous alignment between marks on the back and front of the wafer and a mask can be performed using a pre-existing alignment system. The lithographic projection apparatus is further provided with immersion system for providing a fluid between the lens and the substrate.

    摘要: In one embodiment, front to back side alignment optics are used to project a mark on the back side of a substrate. The front to back side alignment optics are arranged such that the image projected into the image window of the front to back side alignment optics is a translational replica of the mark on the back side of the substrate. One potential advantage of such an arrangement is that any slight inaccuracies in the location of the optical axis do not result in inaccuracies in the image of the substrate mark. The translational replica image can be used for alignment of the substrate.

    摘要: The invention relates to a device manufacturing method comprising identifying a substrate to be processed, performing a manufacturing step of a patterned layer on the substrate, and storing a substrate process history for the substrate. The history may comprise a correction map comprising position errors caused by the manufacturing step. Identifying the substrate may be done by reading an identification sign present on the substrate or by reading an identification code of a lot comprising the substrate and determining a sequence number of the substrate in the lot. Alignment of the substrate with respect to a patterning device of a lithographic apparatus may be corrected using information of the substrate process history. Alternatively or additionally, measured overlay errors may be corrected per substrate using information of the substrate process history.
