  • Publication number: 20230369060
    Abstract: A method for manufacturing a semiconductor device includes forming a photoresist layer that includes a photoresist composition over a wafer to produce a photoresist-coated wafer. The photoresist layer is selectively exposed to actinic radiation to form a latent pattern in the photoresist layer. The latent pattern is developed by applying a developer to the selectively exposed photoresist layer under a first pressure gas flow setting in a development chamber. The photoresist layer is rinsed, under the first pressure gas flow setting, to form a patterned photoresist layer exposing a portion of the wafer in the development chamber. The patterned photoresist layer is spin dried under a second pressure gas flow setting. A pressure of the development chamber under the second pressure gas flow setting is greater than the pressure of the development chamber under the first pressure gas flow setting.

  • Patent number: 11806743
    Abstract: A spin dispenser module and methods for using the same is disclosed. The spin dispenser module includes a cup having a basin with sidewalls and an exhaust, a rotatable platform situated inside the cup adapted for holding and rotating a substrate, a liquid dispenser disposed over the rotatable platform for dispensing a liquid coating material on top of the substrate, one or more ejector inlets disposed over the rotatable platform, the one or more ejectors connected to a negative pressure source, and a motor coupled to the rotatable platform to rate the rotatable platform at different rotational speeds. The one or more ejector inlets may be translatable and/or rotatable with optionally adjustable suction pressure. The ejector inlets operate after a liquid coating material is dispensed to avoid deposition of suspended organic compounds after a coating is formed.
