  • Patent number: 11903202
    Abstract: In one embodiment, a method of manufacturing a semiconductor device includes forming a semiconductor layer including a plurality of metal atoms on a substrate, and forming a first layer including a plurality of silicon atoms and a plurality of nitrogen atoms on the semiconductor layer. The method further includes transferring at least some of the metal atoms in the semiconductor layer into the first layer. and removing the first layer after transferring the at least some of the metal atoms in the semiconductor layer into the first layer. Furthermore, a ratio of a number of the nitrogen atoms relative to a number of the silicon atoms and the nitrogen atoms in the first layer is smaller than 4/7.
