  • Patent number: 11664235
    Abstract: Among other things, one or more systems and techniques for removing a photoresist from a semiconductor wafer are provided. The photoresist is formed over the semiconductor wafer for patterning or material deposition. Once completed, the photoresist is removed in a manner that mitigates damage to the semiconductor wafer or structures formed thereon. In an embodiment, trioxygen liquid is supplied to the photoresist. The trioxygen liquid is activated using an activator, such as an ultraviolet activator or a hydrogen peroxide activator, to create activated trioxygen liquid used to remove the photoresist. In an embodiment, the activation of the trioxygen liquid results in free radicals that aid in removing the photoresist. In an embodiment, an initial photoresist strip, such as using a sulfuric acid hydrogen peroxide mixture, is performed to remove a first portion of the photoresist, and the activated trioxygen liquid is used to remove a second portion of the photoresist.

  • Patent number: 9583352
    Abstract: A method of operating a wafer processing system includes etching a batch of wafers. The method also includes transferring at least a portion of the batch of wafers to a first front opening universal pod (FOUP). The method further includes purging an interior of the first FOUP with an inert gas. The method additionally includes transporting the first FOUP from a first loading port to a second loading port. The method also includes monitoring an elapsed time from the purging. The method further includes performing a second purging of the interior of the first FOUP if the elapsed time exceeds a threshold time. The method additionally includes cleaning the batch of wafers.
