    摘要: A method and apparatus for dispensing a resist solution used in a semiconductor device manufacturing process senses the presence of air bubbles in the solution during delivery through a line feeding a dispensing pump. Air bubbles in the line are sensed by an optical photocoupler that senses changes in the intensity of light refracted through the solution caused by air bubbles entrapped in the solution. The sensor produces an air bubble indicating signal that can be used to activate an alarm or to stop the dispensing process.

    摘要: A method includes directing a beam of radiation along an optical axis toward a workpiece support, measuring a spectrum of the beam at a first time to obtain a first profile, measuring the spectrum of the beam at a second time to obtain a second profile, determining a spectral difference between the two profiles, and adjusting a position of the workpiece support along the optical axis based on the difference. A different aspect involves an apparatus having a workpiece support, beam directing structure that directs a beam of radiation along an optical axis toward the workpiece support, spectrum measuring structure that measures a spectrum of the beam at first and second times to obtain respective first and second profiles, processing structure that determines a difference between the two profiles, and support adjusting structure that adjusts a position of the workpiece support along the optical axis based on the difference.

    摘要: Aspects of the present disclosure provide a method and a system for closing plate take-over in immersion lithography. A plate holder is provided for a closing plate in a wafer holder of an immersion lithography system. An optical detector is provided below the plate holder for determining whether a light signal passing through the closing plate is aligned with the plate holder using the optical detector. If the light signal is aligned, a fluid containment mechanism is lowered, and the closing plate is placed into the plate holder. Alternatively, the fluid containment mechanism is lowered to surface of the closing plate, the closing plate is affixed to the mechanism, and the mechanism is raised with the closing plate. If the light signal is not aligned, an error is triggered and the scanner is stopped.

    摘要: System and method for improving immersion scanner overlay performance are described. One embodiment is a method of improving overlay performance of an photolithography immersion scanner comprising a wafer table having lens cooling water (“LCW”) disposed in a water channel therein, the wafer table having an input for receiving the LCW into the water channel and an output for expelling the LCW from the water channel. The method comprises providing a water tank at least one of the wafer table input and the wafer table output; monitoring a pressure of water in the water tank; and maintaining the pressure of the water in the water tank at a predetermined level.
