    摘要: A method of manufacturing a semiconductor device, a semiconductor device and systems incorporating the same include transistors having a gate metal doped with impurities. An altered work function of the transistor may alter a threshold voltage of the transistor. In certain embodiments, a gate metal of a first MOSFET is doped with impurities. A gate metal of a second MOSFET may be left undoped, doped with the same impurities with a different concentration, and/or doped with different impurities. In some embodiments, the MOSFETs are FinFETs, and the doping may be a conformal doping.

    摘要: In a gate structure and a method of forming the same, a first conductive pattern is formed on a substrate and comprises a metal-containing material. A second conductive pattern is formed on the first conductive pattern, and the second conductive pattern comprises metal and silicon. A third conductive pattern is formed on the second conductive pattern, and the third conductive pattern comprises polysilicon. A gate conductive pattern of an n-type metal-oxide semiconductor (NMOS) transistor, a p-type MOS (PMOS) transistor and a complementary MOS (CMOS) transistor includes the gate structure. The second conductive pattern is interposed between the first and third conductive patterns and the third conductive pattern is prevented from making direct contact with the first conductive pattern, so that polysilicon in the third conductive pattern is sufficiently prevented from being chemically reacted with the metal in the first conductive pattern in advance, thereby improving electrical characteristics of the transistor.

    摘要: A semiconductor device comprising a semiconductor substrate having a first impurity region and a second impurity region, a first gate pattern formed on the first impurity region, and a second gate pattern formed on the second impurity region is disclosed. The first gate pattern comprises a first gate insulation layer pattern, a metal layer pattern having a first thickness, and a first polysilicon layer pattern. The second gate pattern comprises a second gate insulation layer pattern, a metal silicide layer pattern having a second thickness smaller than the first thickness, and a second polysilicon layer pattern. The metal silicide layer pattern is formed from a material substantially the same as the material from which the metal layer pattern is formed. A method for manufacturing the semiconductor device is also disclosed.
