摘要:
Provided are methods of forming a contact plug of a semiconductor device. Methods of forming a contact plug of a semiconductor device may include forming an interlayer insulating layer on a semiconductor substrate on which a lower structure is formed, forming a contact hole in the interlayer insulating layer, the contact hole exposing the lower structure, and forming a W layer and then a WN layer to form a W/WN barrier layer in the contact hole. Methods may include H2 remote plasma treating the W/WN barrier layer, forming a W-plug on the H2 remote plasma treated W/WN barrier layer to fill the contact hole, and chemical mechanical polishing (CMP) the W-plug and then the W/WN barrier layer in order to expose the interlayer insulating layer.
