    摘要： A method of fabricating a semiconductor device having a dual gate allows for the gates to have a wide variety of threshold voltages. The method includes forming a gate insulation layer, a first capping layer, and a barrier layer in the foregoing sequence across a first region and a second region on a substrate, exposing the gate insulation layer on the first region by removing the first capping layer and the barrier layer from the first region, forming a second capping layer on the gate insulation layer in the first region and on the barrier layer in the second region, and thermally processing the substrate on which the second capping layer is formed. The thermal processing causes material of the second capping layer to spread into the gate insulation layer in the first region and material of the first capping layer to spread into the gate insulation layer in the second region. Thus, devices having different threshold voltages can be formed in the first and second regions.

    摘要： A semiconductor device that has a dual gate having different work functions is simply formed by using a selective nitridation. A gate insulating layer is formed on a semiconductor substrate including a first region and a second region, on which devices having different threshold voltages are to be formed. A diffusion inhibiting material is selectively injected into the gate insulating layer in one of the first region and the second region. A diffusion layer is formed on the gate insulating layer. A work function controlling material is directly diffused from the diffusion layer to the gate insulating layer using a heat treatment, wherein the gate insulting layer is self-aligned capped with the selectively injected diffusion inhibiting material so that the work function controlling material is diffused into the other of the first region and the second region. The gate insulating layer is entirely exposed by removing the diffusion layer. A gate electrode layer is formed on the exposed gate insulating layer. A first gate and a second gate having different work functions are respectively formed in the first region and the second region by etching the gate electrode layer and the gate insulating layer
