  • METHOD OF FORMING PATTERNED STRUCTURES
    Publication number: 20230059464
    Abstract: Methods of forming patterned features on a surface of a substrate are disclosed. Exemplary methods include gas-phase formation of a layer comprising an oxalate compound on a surface of the substrate. Portions of the layer comprising the oxalate compound can be exposed to radiation or active species that form exposed and unexposed portions. Material can be selectively deposed onto the exposed or the unexposed portions.

  • METHOD OF TREATING A SUBSTRATE
    Publication number: 20220216059
    Abstract: Methods and related systems for lithographically defining patterns on a substrate are disclosed. An exemplary method includes forming a structure. The method includes providing a substrate to a reaction chamber. The substrate comprises a semiconductor and a surface layer. The surface layer comprises amorphous carbon. The method further comprises forming a barrier layer on the surface layer and depositing a metal-containing layer on the substrate. The metal- containing layer comprises oxygen and a metal.

  • SUBSTRATE PROCESSING APPARATUS AND METHOD
    Publication number: 20210033977
    Abstract: A substrate processing method and apparatus to create a sacrificial masking layer is disclosed. The layer is created by providing a first precursor selected to react with one of a radiation modified and unmodified layer portion and to not react with the other one of the radiation modified and unmodified layer portion on a substrate in a reaction chamber to selectively grow the sacrificial masking layer.
