Abstract:
A method for fabricating a semiconductor device is provided to form high-density second contact plugs of fine patterns by using first contact mask layers and second contact mask layers self-aligned with the first contact mask layers. An interlayer dielectric(110) is formed on a semiconductor substrate(105) in which first and second regions are confined. First contact plugs(115c) are formed on a part of the second region, filling a plurality of first contact holes penetrating the interlayer dielectric. A plurality of first contact mask layers(115a) are formed on the interlayer dielectric in the first region, and a plurality of first dummy mask layers(115b) are formed on the interlayer dielectric in the second region. A plurality of second contact mask layers(135a) are formed on the interlayer dielectric, disposed between adjacent two of the plurality of first contact mask layers. A plurality of second dummy mask layers(135b) are formed on the interlayer dielectric, disposed between adjacent two of the plurality of first dummy mask layers. By using as an etch protection layer the plurality of first contact mask layers and the plurality of second contact mask layers, the interlayer dielectric is etched to form a plurality of second contact holes penetrating the interlayer dielectric on the first region. The plurality of first contact mask layer and the plurality of first dummy mask layers can be formed simultaneously.

Abstract:
A method for forming a contact of a semiconductor device is provided to reduce generation of stepped parts between a cell region and a peripheral region by securing a uniform polishing speed in the cell region and the peripheral region. A semiconductor substrate(100), having a cell region and a peripheral region, is provided. An element layer(200) and an insulating layer(300) for insulating the element layer are formed on the semiconductor substrate. A first mask pattern(400), having a contact pattern part on the cell region and a dummy pattern part on the peripheral region, is formed on the insulating layer. A sacrificial layer having a predetermined thickness and an upper groove is formed on the insulating layer having the first mask pattern. A second mask pattern is formed to bury the groove of the sacrificial layer. A third mask pattern is formed on the sacrificial layer and the second mask pattern in order to expose a contact of the cell region. A contact hole is formed in the insulating layer by etching the insulating layer. The third mask pattern is removed. A conductive layer is formed on the semiconductor substrate in order to bury the contact hole. A planarization of the insulating layer is performed.
