  • Patent number: 12135501
    Abstract: A method of manufacturing a semiconductor device includes forming a photoresist layer over a substrate, including combining a first precursor and a second precursor in a vapor state to form a photoresist material, and depositing the photoresist material over the substrate. A protective layer is formed over the photoresist layer. The photoresist layer is selectively exposed to actinic radiation through the protective layer to form a latent pattern in the photoresist layer. The protective layer is removed, and the latent pattern is developed by applying a developer to the selectively exposed photoresist layer to form a pattern.
