    • A method for manufacturing a semiconductor device is provided to simplify a manufacturing process for a contact plug of the semiconductor device and to reduce a manufacture cost by employing silicon carbide or silicon carbide oxide as a sacrificial dielectric. Lower structures(116) are formed on a semiconductor substrate(110). A sacrificial dielectric(126) is formed on the semiconductor substrate where the lower structures are formed. The sacrificial dielectric is patterned to form a contact hole that exposes a predetermined region of the semiconductor substrate. A contact plug(130) is formed to gap-fill the contact hole. The sacrificial dielectric is a compound including silicon and carbon. When the contact hole is formed, a mask pattern having an opening is formed in the sacrificial dielectric. The opening defines the contact hole. The sacrificial dielectric is patterned by using the mask pattern as an etch mask to form the contact hole. The mask pattern is selectively removed. The opening is formed in the sacrificial dielectric between the lower structures.

    • A method for forming a contact of a semiconductor device is provided to prevent throughput decrease and generation of short phenomenon between adjacent contacts by forming a contact hole having a second spacer on a preliminary contact hole. A conductive layer pattern(106) and a mask pattern(108) are laminated on a semiconductor substrate(100). A conductive structure including a first spacer(112) is formed sidewalls of the conductive layer pattern and the mask pattern. Silicon germanium covering the conductive structure is deposited on the semiconductor substrate to form a sacrificial layer.

A conductive material is gap-filled in the contact hole to form a contact. The sacrificial layer is then removed. An interlayer dielectric is formed on a part where the sacrificial layer is removed.
