    Abstract: On the +X and ?X sides of a projection unit, a plurality of Y heads are arranged in parallel to the X-axis by a predetermined distance half or less than half the effective width of the scale, so that two heads each constantly form a pair and face a pair of Y scales. Similarly, on the +Y and ?Y sides of the projection unit, a plurality of X heads are arranged in parallel to the Y-axis by the predetermined distance described above, so that two heads each constantly form a pair and face a pair of X scales. Of the pair of heads consisting of two heads which simultaneously face the scale, measurement values of a priority head is used, and when abnormality occurs in the measurement values of the priority head due to malfunction of the head, measurement values of the other head is used. Then, by using the measurement values of the two pairs of Y heads and the pair of X heads, a position of a stage within a two-dimensional plane is measured in a stable manner and with high precision.

Then, the fine movement stage is driven individually or integrally with the coarse movement stage by a drive system, based on the positional information measured by the encoder system. In this case, the head of the encoder system can be placed in proximity to the fine movement stage (the grating), which allows a highly precise measurement of the positional information of the fine movement stage by the encoder system.

    Abstract: In a substrate stage, when a Y coarse movement stage moves in the Y-axis direction, an X coarse movement stage, a weight cancellation device, and an X guide move integrally in the Y-axis direction with the Y coarse movement stage, and when the X coarse movement stage moves in the X-axis direction on the Y coarse movement stage, the weight cancellation device moves on the X guide in the X-axis direction integrally with the X coarse movement stage. Because the X guide is provided extending in the X-axis direction while covering the movement range of the weight cancellation device in the X-axis direction, the weight cancellation device is constantly supported by the X guide, regardless of its position. Accordingly, a substrate can be guided along the XY plane with good accuracy, even if a member (for example, a surface plate and the like) that has a guide surface large enough to cover the total movement range of the weight cancellation device is not provided.

    Abstract: Some embodiments of the present disclosure relate to a method of overlay control which utilizes a deformable electrostatic chuck. The method comprises exposing a substrate to radiation which is reflected off of a reticle. The reticle is mounted to a deformable electrostatic chuck by a plurality of raised contacts, where each raised contact is configured to independently vary in height from a surface of the deformable electrostatic chuck. After exposure of the substrate to radiation which is reflected off of the reticle, a displacement between a first alignment shape formed on a first layer disposed on a surface of the substrate and a second alignment shape formed by the exposure is measured. The height of one or more of the plurality of raised contact is changed based upon the displacement to alter a surface topology of the reticle, which negates some effects of clamping topology.

  • Patent number: 8970820
    Abstract: A carrier apparatus positions a chuck member above a wafer mounted on a fine movement stage, relatively moves the chuck member and the fine movement stage in a vertical direction, makes the chuck member approach a position which is a predetermined distance away from the upper surface of the wafer, makes the chuck member hold the wafer from above in a non-contact manner, and makes the chuck member holding the wafer and the fine movement stage move apart within a predetermined plane after making the chuck member holding the wafer and the fine movement stage move apart in the vertical direction. Further, the carrier apparatus loads the wafer held in a non-contact manner from above by the chuck member on the fine movement stage.

  • Patent number: 8970821
    Abstract: A positioning apparatus includes a stage, a base, a supporting mechanism which is arranged between the stage and the base and supports the stage with a supporting portion having a spring characteristic, an actuator which is arranged between the stage and the base so as to drive the stage, and a controller which controls the actuator so as to reduce a position error of the stage relative to a target position and cancel at least part of a force acting on the stage due to the spring characteristic of the supporting portion, based on the position error of the stage and a variation of a relative position between the stage and the base.

  • Publication number: 20150055113
    Abstract: According to one embodiment, a pattern formation method includes preparing a mask pattern for interference, producing Talbot interference, and forming a pattern by blocking a part of interference light. The mask pattern for interference is arranged periodically a plurality of light transmissive portions. The Talbot interference is based on a transmitted light. The transmitted light is transmitted through the light transmissive portions by applying a light to the mask pattern for interference. The part of interference light is produced by the Talbot interference by means of a mask pattern for light blocking and applying another part of the interference light transmitted through the mask pattern for light blocking to a exposure object member.

  • Patent number: 8964167
    Abstract: The present invention provides a cylindrical magnetic levitation stage and an exposure apparatus, which can form a nanoscale pattern of a large area directly on the surface of a large cylinder. The present invention provides an exposure apparatus including a new type of cylindrical magnetic levitation stage, which can levitate, rotate, and move a cylinder in the axial direction by the principle of magnetic levitation in a non-contact manner and form a nanoscale pattern on the surface of the cylinder, and a light source for irradiating light on the surface of the cylinder, thereby reducing the position error of the cylindrical magnetic levitation stage to a nanoscale size and correcting the error caused by mechanical processing in real time.

  • Publication number: 20150036111
    Abstract: In an exposure station, positional information of a holding member that holds a wafer is measured by a first measurement system including a measurement member, and in a measurement station positional information of the holding member that holds a wafer is measured by a second measurement system including another measurement member. An exposure apparatus has a third measurement system which can measure positional information of the holding member when the holding member is carried from the measurement station to the exposure station. A controller, coupled to the first and the second measurement systems, controls a movement of the holding member based on the positional information measured by the first measurement system in the exposure station and also controls a movement of the holding member based on the positional information measured by the second measurement system in the measurement station.
