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.
