摘要:
Semiconductor devices are fabricated using a plasma process with a non-silane gas that includes deuterium, and which may result in improved device reliability and/or other improved device operational characteristics. One such method can include forming a gate oxide layer on a transistor region, which is defined on a substrate, and forming a gate electrode on the gate oxide layer. An etch stop layer is formed on the gate oxide layer and the gate electrode. A plasma process is performed on the interface between the gate oxide layer and the substrate using a non-silane treatment gas including deuterium. An interlayer dielectric layer is formed on the etch stop layer. A bottom metal line is formed on the interlayer dielectric layer.

A method of fabricating a semiconductor integrated circuit (IC) device can include forming a first silicide layer on at least a portion of a transistor on a substrate, forming nitrogen in the first silicide layer to form a second silicide layer, forming a first stress layer having a tensile stress on the substrate having the transistor formed thereon, and irradiating the first stress layer with ultraviolet (UV) light to form a second stress layer having greater tensile stress than the first stress layer.

In some methods of manufacturing transistors, a gate electrode and a gate insulation layer pattern are stacked on a substrate. Impurity regions are formed at portions of the substrate that are adjacent to the gate electrode by implanting Group III impurities into the portions of the substrate. A diffusion preventing layer is formed on the substrate and covering the gate electrode. A nitride layer is formed on the diffusion preventing layer. The substrate is thermally treated to form a strained silicon region in the substrate between the impurity regions and to activate the impurities in the impurity regions. A high performance PMOS transistor and/or CMOS transistor may thereby be manufactured on the substrate.

In a method of manufacturing a semiconductor device, a mask pattern is formed on an active region of a substrate. An exposed portion of the substrate is removed to form a trench in the substrate. A preliminary first insulation layer is formed on a bottom and sidewalls of the trench and the mask pattern. A plasma treatment is performed on the preliminary first insulation layer using fluorine-containing plasma to form a first insulation layer including fluorine. A second insulation layer is formed on the first insulation layer to fill the trench. A thickness of a gate insulation layer adjacent to an upper edge of the trench may be selectively increased, and generation of leakage current may be reduced.

In a method of manufacturing a semiconductor device, a conductive layer pattern may be formed on a substrate. An oxide layer may be formed on the substrate to cover the conductive layer pattern. A diffusion barrier layer may be formed by treating the oxide layer to increase an energy required for a diffusion of impurities. An impurity region may be formed on the substrate by implanting impurities into the conductive layer pattern and a portion of the substrate adjacent to the conductive layer pattern, through the diffusion barrier. The impurities in the conductive layer pattern and the impurity region may be prevented or reduced from diffusing, and therefore, the semiconductor device may have improved performance.
