  • Publication number: 20150036118
    Abstract: A partial section of an aerial image measuring unit is arranged at a wafer stage and part of the remaining section is arranged at a measurement stage, and the aerial image measuring unit measures an aerial image of a mark formed by a projection optical system. Therefore, for example, when the aerial image measuring unit measures a best focus position of the projection optical system, the measurement can be performed using the position of the wafer stage, at which a partial section of the aerial image measuring unit is arranged, in a direction parallel to an optical axis of the projection optical system as a datum for the best focus position. Accordingly, when exposing an object with illumination light, the position of the wafer stage in the direction parallel to the optical axis is adjusted with high accuracy based on the measurement result of the best focus position.

  • Patent number: 8908146
    Abstract: An actuator system is disclosed having a first actuator (XP1) and a second actuator (XP2) configured to control a relative position of optical components of a lithographic apparatus. The first actuator (XP1) is configured to provide a displacement, parallel to an actuation direction, between a mounting point of a first component of the lithographic apparatus and a second component of the lithographic apparatus. The second actuator (XP2) is configured to provide a displacement parallel to the actuation direction between a reference mass (M1) associated with the second actuator (XP2) and the mounting point of the first component of the lithographic apparatus. The second actuator (XP2) may be driven such that the displacement between the second actuator (XP2) and the reference mass (M1) increases the apparent stiffness of the first actuator (XP1).

    Abstract: A method of manufacturing a semiconductor device in which the alignment accuracy of an immersion exposure device is maintained even when exposure steps are carried out intermittently. In the method, a substrate is placed on a stage of an exposure device (substrate placing step). Then, a first liquid is supplied to between the substrate and the optics system of the exposure device to expose the substrate through the first liquid (exposure step). A second liquid is supplied from a different place from the first liquid to a drainage groove provided around the stage at least in a period other than when the first liquid is supplied onto the stage, in order to suppress change in the temperature of the exposure device.

  • Publication number: 20140354972
    Abstract: A controller inclines a movable body with respect to an XY plane at an angle ? in a periodic direction of a grating, based on a measurement value of an interferometer which measures an angle of inclination of the movable body to the XY plane, and based on a measurement value of an encoder system and information of angle ? before and after inclination, and computes an Abbe offset quantity of the grating surface with respect to a reference surface which serves as a reference for position control of the movable body in the XY plane. The controller drives the movable body, based on positional information of the movable body in the XY plane measured by the encoder system and a measurement error of the encoder system corresponding to an angle of inclination of the movable body to the XY plane due to Abbe offset quantity of the grating surface.

  • Patent number: 8896809
    Abstract: A lithographic apparatus and method is disclosed to reduce the exposure time that a substrate spends within a main lithographic apparatus by pre- (or post-) exposing one or more edge devices on the substrate. Because an edge device does not ultimately yield a useful device, it can be exposed with a lithographic apparatus that has a lower resolution than that used to expose one or more of the other, complete devices produced from the substrate. Therefore, the pre- (or post-) exposure of an edge device can be performed using a less complex, and less expensive, lithographic device.

  • Patent number: 8896810
    Abstract: A liquid immersion scanning exposure system utilizes an immersion liquid confined within a watertight lens hood having a base portion formed from a solid optical element. During operation, a bottom portion of a lens assembly is disposed within the immersion liquid and the solid optical element is placed upon a photoresist material or layer (to be patterned). The lens assembly moves laterally through the immersion liquid parallel to the photoresist material. Because the solid optical element separates the immersion liquid from the photoresist material and does not move relative to the photoresist material, the photoresist material does not contact with the immersion liquid and the solid optical element and is not susceptible to damage or scratching by the solid optical element.

  • Patent number: 8896811
    Abstract: A method for positioning a substage, supported by a main stage, relative to a reference object, the substage moveable in a direction between a first and second position relative to the main stage. The method includes positioning the first stage using a passive force system that is activated by positioning the main stage. The passive force system includes two magnet systems, each magnet system being configured to apply a force in the direction to the first stage with respect to the second stage in a non-contact manner, the forces resulting in a resultant force applied to the first stage in the direction by the passive force system. A magnitude and/or a direction of the resultant force depends on the position of the first stage relative to the second stage, and the first stage has a zero-force position between the first and second position in which the resultant force is zero.

  • Publication number: 20140340667
    Abstract: An exposure apparatus is equipped with an encoder system which measures positional information of a wafer stage by irradiating a measurement beam using four heads installed on the wafer stage on a scale plate which covers the movement range of the wafer stage except for the area right under a projection optical system. Placement distances of the heads here are each set to be larger than width of the opening of the scale plates, respectively. This allows the positional information of the wafer stage to be measured, by switching and using the three heads facing the scale plate out of the four heads according to the position of the wafer stage.
