    摘要: A method of forming a field effect transistor includes forming a vertical channel protruding from a substrate including a source/drain region junction between the vertical channel and the substrate, and forming an insulating layer extending on a side wall of the vertical channel toward the substrate to beyond the source/drain region junction. The method may also include forming a nitride layer extending on the side wall away from the substrate to beyond the insulating layer, forming a second insulating layer extending on the side wall that is separated from the channel by the nitride layer, and forming a gate electrode extending on the side wall toward the substrate to beyond the source/drain region junction.

    摘要: A wire forming method for a semiconductor device includes the steps of depositing an insulation material on a semiconductor substrate and patterning the insulation material to form a first insulation layer, forming a lower capping layer on the first insulation layer, etching the lower capping layer and the first insulation layer to form a first contact hole that exposes a first part of the semiconductor substrate, forming a wire layer over the capping layer and the first part of the semiconductor substrate, performing a chemical and mechanical polishing (CMP) process with respect to the wire layer and the lower capping layer to expose the first insulation layer, forming a second insulation layer over the wire layer and the first insulation layer, and etching the first and second insulation layers to form a second contact hole that exposes a second part of the semiconductor substrate. The wire forming method can prevent the lifting of the wire layer, the splitting of the lower insulation layer, and the formation of a protrusion n the second contact hole.

    摘要: A method for making a capacitor of a semiconductor memory device capable of providing increased capacitance without degraded resolution, as well as without the removal of any interlayer insulation layers upon formation of a lower electrode for the capacitor, wherein after formation of an access transistor on a semiconductor substrate, a first interlayer insulation layer for planarization of a surface of the semiconductor substrate and a second interlayer insulation layer for formation of the capacitor lower electrode are formed. After formation of an opening for exposing a part of an impurity diffusion region of the access transistor by etching a part of the first and second interlayer insulating layers, a spacer is formed within the opening. Further, after deposition of a conductive layer for the capacitor lower electrode onto a surface of the substrate, a planarization process is carried out until a part of the upper surface of the spacer is exposed. Finally, after removal of the exposed spacer, the dielectric layer and a conductive layer for the upper electrode of the capacitor are formed in sequence. The method does not require any additional insulation layer evaporation process, since the interlayer insulation layer for formation of the reverse storage electrode could be used for formation of a gate contact of a logic region, without removal. Consequently, simplification of fabrication process for a capacitor is achieved.
