    摘要: Provided is a method of fabricating an integrated circuit semiconductor device. The method may include forming a plurality of gate patterns spaced apart from each other on a semiconductor substrate, the plurality of gate patterns including gate electrodes and gate capping patterns. After an interlayer insulating layer is formed to insulate the gate patterns, the interlayer insulating layer and the gate capping patterns may be planarized by etching until top surfaces of the gate electrodes are exposed. Gate metal silicide layers may be selectively formed on the gate electrodes.

    摘要: In a method for forming a planarized layer on a semiconductor device having concave and convex structures, a dielectric film is formed on a semiconductor substrate; a photoresist pattern is formed to have a thickness on a portion of the dielectric film other than a convex portion greater than h/n (h and n are real numbers of one or more) to remove the convex portion of the dielectric film by a depth of approximately h. The photoresist pattern is re-flowed to have a thickness below h/n at a portion from an edge of the convex portion to a slant portion of the dielectric film. The dielectric film is etched using an etchant having a selectivity of 1:n between the photoresist pattern and the dielectric film. An edge of the photoresist pattern is made thin by re-flowing thereby minimizing a pillar, hence allowing simple, fast, planarization of the dielectric film.
