    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 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.

    摘要: In a method of fabricating a CMOS transistor, and a CMOS transistor fabricated according to the method, the characteristics of first and second conductivity type MOS transistors are both simultaneously improved. At the same time, the fabrication process is simplified by reducing the number of masks required. The method includes amorphizing the active region of only the second conductivity type MOS transistor, and performing selective etching to form a first recessed region of a first depth in the active region of the first conductivity type MOS transistor and a second recessed region of a second depth that is greater than the first depth in the active region of the second conductivity type MOS transistor. Selective epitaxial growth is performed in the first and second recessed regions to form an elevated epitaxial layer that fills the first recessed region and extends to a level that is above the upper surface of the semiconductor substrate and to form a recessed epitaxial layer that fills the second recessed region.
