    摘要: The present invention relates to a method of forming a contact in semiconductor device, more particularly, to a method of forming a borderless contact in semiconductor device which minimizes loss of field oxide on forming a contact hole, reducing leakage current at an interface between an active area and a field area and preventing another loss of silicon and silicide in the active area by forming a barrier layer on a field oxide layer for separating devices in order to enhance a process margin of forming the contact hole in the active area due to a reduced design rule and an increased device integrity. The present invention includes the steps of forming a trench on a semiconductor substrate wherein the trench defines an active area and a field area, filling up the trench with an insulating layer, forming a barrier layer just on the insulating layer, forming a transistor in the active layer wherein the transistor has an impurity diffusion region, forming an insulating interlayer on a surface of the substrate including the transistor and the barrier layer, and forming at least a contact hole by removing a predetermined portion of the insulating interlayer wherein the contact hole exposes both a portion of the impurity diffusion region and another portion of the barrier layer.

    摘要: A fin field-effect transistor (FinFET) device includes a fin-shaped active region having first and second source/drain regions therein and a channel region therebetween vertically protruding from a semiconductor substrate. A gate electrode is formed on an upper surface and sidewalls of the channel region. First and second source/drain contacts are formed on respective upper surfaces and sidewalls of the first and second source/drain regions of the fin-shaped active region at opposite sides of the gate electrode. The channel region may be narrower than the first and second source/drain regions of the fin-shaped active region.

    摘要: Integrated circuit field effect transistor devices include a substrate having a surface and an active channel pattern on the surface. The active channel pattern includes channels that are stacked upon one another and are spaced apart from one another to define at least one tunnel between adjacent channels. A gate electrode surrounds the channels and extends through the at least one tunnel. A pair of source/drain regions also is provided. Integrated circuit field effect transistors are manufactured, by forming a pre-active pattern on a surface of a substrate. The pre-active pattern includes a series of interchannel layers and channel layers stacked alternately upon each other. Source/drain regions are formed on the substrate at opposite ends of the pre-active pattern. The interchannel layers are selectively removed to form tunnels. A gate electrode is formed in the tunnels and surrounding the channels.

    摘要: According to some embodiments, a semiconductor device includes a lower semiconductor substrate, an upper silicon pattern, and a MOS transistor. The MOS transistor includes a body region formed within the upper silicon pattern and source/drain regions separated by the body region. A buried insulating layer is interposed between the lower semiconductor substrate and the upper silicon pattern. A through plug penetrates the buried insulating layer and electrically connects the body region with the lower semiconductor substrate, the through plug positioned closer to one of the source/drain regions than the other source/drain region. At least some portion of the upper surface of the through plug is positioned outside a depletion layer when a source voltage is applied to the one of the source/drain regions, and the upper surface of the through plug is positioned inside the depletion layer when a drain voltage is applied to the one region.
