Abstract: An apparatus for stabilizing a scanning system during lithographic processing comprises a baseframe, a reaction mass, and a pair of flexures connecting the reaction mass to the baseframe. The apparatus also comprises a second reaction mass and a second pair of flexures, placed in parallel to the first to form a split reaction mass system. The apparatus is configured such that, upon acceleration of a stage movably coupled to the reaction masses, a resulting load is split substantially evenly between the first and second reaction masses. Also upon acceleration of the stage, the first reaction mass rotates in the opposite direction of the second reaction mass, resulting in a net moment reaction on the baseframe of approximately zero.

Abstract: In a reflective lithographic projection apparatus, shifts in the image of a pattern of a mask in the scanning direction caused by variations in the position of the pattern surface of the mask along the optical axis are corrected by shifting of the relative position of the mask and/or the substrate in the scanning direction. Correction of the image rotation error may also be accomplished by rotation of the relative positions of the mask and/or the substrate about the optical axis. Variations in the position of the pattern surface of the mask along the optical axis may be determined by interferometers upon installation of the mask to the lithographic projection apparatus. The variations may be mapped and stored to provide control of the lithographic projection apparatus.

Abstract: A gas gauge proximity sensor modulates a gas stream that is used to feed reference and measurement air gauges, respectively, in a reference portion proximate a reference surface and a measurement portion proximate a measurement surface. The gas stream can be modulated at a frequency at which there is minimal acoustical interference energy (e.g., minimal noise) in demodulated output signal. The sensor output can be filtered so that a measurement signal includes only the modulated frequency and side bands of that frequency to include the desired response band of the device as a whole. The filtered signal can be demodulated using a demodulator operating at a same frequency as the modulator to produce the demodulated output signal. In this embodiment, substantially only ambient acoustical energy in the band pass region may interfere with the device operation. Alternatively, the modulation can be introduced through the reference portion. A reference nozzle sets up a pressure field with the reference surface. A carrier frequency can be generated by mechanical motion of the reference surface. For example, this motion can be introduced by a mechanism like a piezoelectric device or a voice coil coupled to the reference surface. The modulated gas flow combines with the other gas flows to produce a modulated combined gas flow.

Abstract: A lithography system and method are used to increase throughput using multiple reticles to pattern multiple substrates that are positioned with respect to one another according to a predetermined sequence. For example, during a first exposure period a first reticle patterns a first set of substrates, during a second exposure period a second reticle patterns a second set of substrates, during a third exposure period the first reticle patterns a third set of substrates, etc., until all desired substrates are patterned. It is to be appreciate that after the first and second reticles are complete, third and fourth reticles can pattern the first, second, third, etc. sets of substrates.

Abstract: A trajectory planning process receives data generated by high-level control software. This data defines positions and scan velocities. The trajectory planning process creates sequences of constant acceleration intervals that allow critical motions to be executed at maximum throughput. The trajectory planning process outputs a profile. A profile executor, using the profile output by the trajectory planner process, generates continuous synchronized, filtered, multi-axis position and acceleration commands that drive control servos. Time intervals generated by the trajectory planner are quantized to be integer multiples of a real time clock period. The trajectory planner outputs have infinite jerk, but are smoothed by filters in the profile executor to both limit jerk and minimize servo-tracking errors. The trajectory planner allows time for the profile executor filters, but does not restrict fine tuning of the shape of these filters, provided that the width of the tuned filter does not exceed the allowed time.

Abstract: A system and method that eliminate or substantially reduce slippage of a pattern generator with respect to a pattern generator holding device during a scanning portion of an exposure operation. In first and second examples, this is done by either (a) continuously or (b) when needed concurrently using first and second pattern generator holding systems to hold the pattern generator to the pattern generator holding device. In these examples, the first pattern generator holding systems utilizes an electrostatic system to attract the pattern generator to the pattern generator holding device and the second pattern generator holding system utilizes a vacuum system to attract the pattern generator to the pattern generator holding device.
