Latest Patents

Montgomery's latest patents include a method of producing a patterned photoresist used to prepare high-performance photomasks. This innovation significantly reduces variations in critical dimensions from the target for features in a patterned photoresist. The patterned photoresist is generated during the fabrication of a reticle (photomask) for semiconductor processing. The ability to maintain the targeted critical dimension of patterned photoresist features, which are imaged using a direct write process, depends on a photoresist binder resin system that provides a dense structure to hinder the movement of photoacid-labile groups after irradiation. Additionally, her method of extending the stability of a photoresist during direct writing of an image eliminates the environmental sensitivity of a chemically amplified photoresist by overcoating it with a thin protective topcoat. This topcoat is pH adjusted to be as neutral as possible, enhancing stability during the long writing periods required for photomask patterning.
