Patent ID: 11903202
Assignee: KIOXIA CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A method of manufacturing a semiconductor device, comprising:
forming a semiconductor layer including a plurality of metal atoms on a substrate;
forming a first layer including a plurality of nitrogen atoms on the semiconductor layer;
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,
wherein the at least some of the metal atoms in the semiconductor layer are transferred into the first layer by a thermal treatment of the semiconductor layer, the thermal treatment being performed in a chamber same as a chamber in which the semiconductor layer is formed, or
wherein the first layer is removed in a chamber same as the chamber in which the semiconductor layer is formed.
