    摘要: An isolation method for a semiconductor device where an insulating mask layer is formed on desired regions of a semiconductor substrate. A trench is formed to a desired depth in the semiconductor substrate using the insulating mask layer as a mask. An oxide layer is formed on the insulating mask layer and on the sidewall of the trench. A trench liner layer is formed on the oxide layer. An insulating filler layer is formed in the trench in the semiconductor substrate, on which the trench liner layer is formed, so as to fill the trench. The insulating mask layer is removed. According to the isolation method for a semiconductor device, it is possible to reduce dents from occurring along the edge of the trench, reduce a bird's beak type oxide layer from occurring at an interface between the insulating mask layers, decrease the leakage current, or improve the electrical characteristics, such as threshold voltage.

    摘要: A method of forming a T-shaped isolation layer, a method of forming an elevated salicide source/drain region using the same, and a semiconductor device having the T-shaped isolation layer are provided. In the method of forming the T-shaped isolation layer, an isolation layer having a narrow trench region in the lower portion thereof and a wide trench region in the upper portion thereof is formed on a semiconductor substrate. Also, in the method of forming the elevated salicide source/drain region, the method of forming the T-shaped isolation layer is used. In particular, conductive impurities can also be implanted into the lower portion of the wide trench region which constitutes the head of the T-shaped isolation layer and is extended to both sides from the upper end of the narrow trench region by controlling the depth of the wide trench region in an ion implantation step for forming the source/drain region.

    摘要: In a metal-oxide semiconductor (MOS) transistor with an elevated source/drain structure and in a method of fabricating the MOS transistor with the elevated source/drain structure using a selective epitaxy growth (SEG) process, a source/drain extension junction is formed after an epi-layer is formed, thereby preventing degradation of the source/drain junction region. In addition, the source/drain extension junction is partially overlapped by a lower portion of the gate layer, since two gate spacers are formed and two elevated source/drain layers are formed in accordance with the SEG process. This mitigates the short channel effect and reduces sheet resistance in the source/drain layers and the gate layer.

    摘要: A method of fabricating a trench isolation structure in a high-density semiconductor device that provides an isolation characteristic that is independent of the properties of adjacent MOS transistor devices, wherein a first trench in a first isolation area and a second trench implanted are formed on a semiconductor substrate, a nitrogen (N)-rich silicon layer is formed on the sidewall in a second isolation area, a subsequent oxidation process may be employed to fabricate oxide layers, each having a different thickness, on the sidewall surfaces of the first and second trenches. When the first and second oxide-layered trenches are filled with a stress relief liner and a dielectric material, the different thicknesses of the oxides prevent leakage currents from flowing to an adjacent semiconductor device, regardless of the doping properties of each device.

    摘要: A method of manufacturing a bipolar device including pre-treatment using germane gas and a bipolar device manufactured by the same. The method includes forming a single crystalline silicon layer for a base region on a collector region; and forming a polysilicon layer for an emitter region thereon. Here, before the polysilicon layer is formed, the single crystalline silicon layer is pre-treated using germane gas. Thus, an oxide layer is removed from the single crystalline silicon layer, and a germanium layer is formed on the single crystalline silicon layer, thus preventing Si-rearrangement.
