    摘要: A first mask layer pattern including a plurality of parallel line portions is formed on an etch target layer on a semiconductor substrate. A sacrificial layer is formed on the first mask layer pattern and portions of the etch target layer between the parallel line portions of the first mask layer pattern. A second mask layer pattern is formed on the sacrificial layer, the second mask layer pattern including respective parallel lines disposed between respective adjacent ones of the parallel line portions of the first mask layer pattern, wherein adjacent line portions of the first mask layer pattern and the second mask layer pattern are separated by the sacrificial layer. A third mask layer pattern is formed including first and second portions covering respective first and second ends of the line portions of the first mask layer pattern and the second mask layer pattern and having an opening at the line portions of the first and second mask layer patterns between the first and second ends. The sacrificial layer and the etch target layer are etched using the third mask layer pattern, the first mask layer pattern and the second mask layer pattern as a mask to thereby form a plurality of parallel trenches in the etch target layer between the line portions of the first and second mask layer patterns. Conductive lines may be formed in the trenches.

    摘要: A novel method for forming contact holes is disclosed. According to the present invention, a silicon substrate is prevented from being over-etched by performing a two-step etching process. The first step is to etch a thick interlayer insulating layer until a thin etch stopper layer, formed beneath the interlayer insulating layer, is exposed. The second step is to over-etch the thin etch stopper layer. With this method, a lower capacitor electrode or a bit line can be prevented from being short-circuited with a well region of the silicon substrate, thereby reducing leakage currents.

    摘要: An integrated circuit field effect transistor includes contact pads which are separated by sidewall spacers. A first pad which electrically contacts one of the spaced-apart source and drain regions extends onto the gate electrode top, to define a first pad sidewall on the gate electrode top. A first capping layer on the first pad defines a first capping layer sidewall on the first pad. A first insulating sidewall spacer is formed on the first pad sidewall and on the first capping layer sidewall. A second pad, electrically contacting the other of the source and drain regions, extends onto the gate electrode top and contacts the first insulating sidewall spacer. A second capping layer may be formed on the second pad, opposite the substrate, to define a second capping layer sidewall on the first capping layer. A second insulating sidewall spacer may be formed on the second pad sidewall and on the second capping layer sidewall. Apertures may be formed in the capping layer and in the second capping layer to expose the first pad and the second pad, respectively. A storage capacitor may be electrically connected to the first pad and a bit line may be electrically connected to the second pad. By forming the first and second pads of separate layers in separate steps, and by separating the pads by an insulating sidewall spacer, process margins can be increased and reliability and yield can be increased.
