  • 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.
