  • Publication number: 20180047580
    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.

  • Publication number: 20170176864
    Abstract: Embodiments of the present invention provide methods for optimizing a lithographic projection apparatus including optimizing projection optics therein. The current embodiments include several flows including optimizing a source, a mask, and the projection optics and various sequential and iterative optimization steps combining any of the projection optics, mask and source. The projection optics is sometimes broadly referred to as “lens”, and therefore the optimization process may be termed source mask lens optimization (SMLO). SMLO may be desirable over existing source mask optimization process (SMO) or other optimization processes that do not include projection optics optimization, partially because including the projection optics in the optimization may lead to a larger process window by introducing a plurality of adjustable characteristics of the projection optics.
