  • Patent number: 8143160
    Abstract: In a method of forming a contact plug of a semiconductor device, a nitride layer is prevented from being broken by forming a passivation layer over the nitride layer when contact holes are formed by etching an insulating layer between select lines formed over a semiconductor substrate. In an etch process of forming the contact plug, the passivation layer formed on sidewalls of the select lines is formed twice to protect the sidewalls of the select lines. Accordingly, the sidewalls of the select lines can be prevented from being damaged. Consequently, a process margin necessary to form a contact plug can be increased and, therefore, a smaller contact plug can be formed.
