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： The invention provides systems and processes that form the inverse (photographic negative) of a patterned first coating. The patterned first coating is usually provided by a resist. After the first coating is patterned, a coating of a second material is provided thereover. The uppermost layer of the second coating is removed, where appropriate, to expose the patterned first coating. The patterned first coating is subsequently removed, leaving the second coating material in the form of a pattern that is the inverse pattern of the first coating pattern. The process may be repeated with a third coating material to reproduce the pattern of the first coating in a different material. Prior to applying the second coating, the patterned first coating may be trimmed by etching, thereby reducing the feature size and producing sublithographic features. In addition to providing sublithographic features, the invention gives a simple, efficient, and high fidelity method of obtaining inverse coating patterns.

摘要： A system and method are disclosed for monitoring characteristics of a rotating substrate. As the substrate rotates in an environment, an incident light beam is emitted onto the substrate near an axis about which the substrate rotates. The emission of the incident beam is controlled as a function of the angular orientation of the substrate, so that the incident beam selectively interrogates a central region of the substrate to facilitate measuring and/or inspecting characteristics of the substrate.
