    摘要: The present invention provides a system and methodology for dummy-dispensing resist though a dispense head while mitigating waste associated with the dummy-dispense process. The dummy dispensed resist is returned to a reservoir from which it was taken. Between substrate applications, the dispense head can be positioned to dispense resist into a return line. The flow of resist from the dispense head keeps resist from drying at the dispense head. By funneling the dummy-dispensed resist into a return line with low volume, for example, waste from the dummy-dispensing process can be mitigated.

    摘要: A system and method is provided for monitoring and controlling the contaminant particle count contained in an aerosol during a photoresist coating and/or development process of a semiconductor. The monitoring system monitors the contaminate particle count present in the environment of the photoresist coating and/or development process, such as in a process chamber or a cup, enclosing the wafer during the process. The present invention employs in situ laser scattering or laser doppler anemometry techniques to detect the particle count level in the chamber or cup. A plurality of lasers and detectors can be positioned at different heights in or outside of a chamber or cup to facilitate detecting particles at different height levels. A laser could be used in conjunction with mirrors to provide a similar measurement. The particle count level can be used to compare with the defect level, so that it can be determined if a cleaner environment and/or process should be implemented.

    摘要: The present invention is directed to a system and a method for controlling a thin film formation on a moving substrate as part of a process for manufacturing an integrated circuit. The invention involves the use of scatterometry to control the thin film formation process by analyzing the thin film on the moving substrate in a periodic manner. A registration feature associated with the moving substrate can be utilized in conjunction with a signaling system to determine a position of the moving substrate, whereby a repeatable analysis of a corresponding location on the moving substrate can be performed. Scatterometry permits in-situ measurements of thin film formation progress, whereby thin film formation process conditions can be controlled in a feedback loop to obtain a targeted result. Scatterometry can also be facilitated by providing a grating pattern on a non-production portion of the substrate.
