  • Publication number: 20240130082
    Abstract: Methods and apparatus for processing a substrate are provided herein. For example, an apparatus for processing a substrate comprises a process chamber configured to process a substrate, a substrate support comprising a heat sink configured to cool the substrate support during operation and a water trap panel comprising a pumping ring configured to cool the water trap panel such that the water trap panel condenses water vapor molecules and drops a process chamber pressure during operation, and a chiller operably coupled to the substrate support and configured to supply a cooling fluid to the substrate support via a cooling fluid line that connects to the heat sink and the pumping ring via a serial configuration or a parallel configuration.

  • Patent number: 8120748
    Abstract: A method of optimizing lithographic processing to achieve substrate uniformity, is presented herein. In one embodiment, The method includes deriving hyper-sampled correlation information indicative of photoresist behavior for a plurality of wafer substrates processed at pre-specified target processing conditions. The derivation includes micro-exposing subfields of the substrates with a pattern, processing the substrates at the various target conditions, determining photoresist-related characteristics of the subfields (e.g., Bossung curvatures), and extracting correlation information regarding the subfield characteristics and the different target processing conditions to relate the target conditions as a function of subfield characteristics. The method then detects non-uniformities in a micro-exposed subsequent substrate processed under production-level processing conditions and exploits the correlation information to adjust the production-level conditions and achieve uniformity across the substrate.
