A method for manufacturing a transistor may comprise: defining an active area on a semiconductor substrate, and forming on the active area a gate stack, a primary spacer, and source/drain regions, wherein the primary spacer surrounds the gate stack, and the source/drain regions are embedded in the active area and self-aligned with opposite sides of the primary spacer; forming a semiconductor spacer surrounding the primary spacer, and cutting off the ends of the semiconductor spacer in the width direction of the gate stack so as to isolate the source/drain regions from each other; and covering the surfaces of the source/drain regions and the semiconductor spacer with a layer of metal or alloy, and annealing the resulting structure, so that a metal silicide is formed on the surfaces of the source/drain regions, and so that the semiconductor spacer is transformed into a silicide spacer simultaneously. As such, the risk of transistor failure due to atoms or ions of Ni entering the channel region through the source/drain extension regions is reduced.

    摘要: The present invention relates to a semiconductor device and a method for manufacturing the same. According to the present invention, when a gate is formed via a replacement gate process, a portion of a work function metal layer and a portion of a first metal layer are removed after the work function metal layer and the first metal layer are formed, and then the removed portions are replaced with a second metal layer. A device having such a gate structure greatly reduces the resistivity of the whole gate, due to a portion of the work function metal layer with a high resistivity being removed and the removed portion being filled with the second metal layer with a low resistivity, thereby AC performances of the device are improved.
