  • Publication number: 20160005644
    Abstract: Provided are methods of surface treatment, semiconductor devices and methods of forming the semiconductor device. The methods of forming the semiconductor device include forming a first oxide layer and a second oxide layer on a substrate. The first and second oxide layers are patterned to form a contact hole exposing the substrate. A sidewall of the first oxide layer exposed by the contact hole reacts with HF to form a first reaction layer and a sidewall of the second oxide layer exposed by the contact hole reacts with NH3 and HF to form a second reaction layer. The first and second reaction layers are removed to enlarge the contact hole. A contact plug is formed in the enlarged contact hole.
