    摘要: By suppressing a short-channel effect of a MIS field-effect transistor and reducing a fringing capacitance of a gate, a signal delay in the transistor can be shortened. The MIS field-effect transistor is formed d by forming a side-wall spacer from a dielectric having a large dielectric constant and then forming an impurity diffusion layer area with the side-wall spacer used as an introduction end in an ion implantation process to introduce impurities. In this case, the side wall of the side-wall spacer having the large dielectric constant has an optimum film thickness in the range from 5 nm to 15 nm, which is required for achieving a large driving current. On the other hand, a side-wall spacer on an outer side is made of a silicon-dioxide film, which is a dielectric having a small dielectric constant.

    摘要: In a full depletion MISFET, there is a limit to control on a threshold voltage Vth by an impurity concentration in principle when a monocrystalline SOI layer becomes thin on the order of a few tens of nm. It was thus difficult to simultaneously realize predetermined Vth of both n and p types in a complementary MISFET. A gate insulating film for the MISFET is formed as a laminated layer of a metal oxide and an oxynitride. A gate electrode is formed using a polycrystalline Si semiconductor film of the same conductivity type as a source-drain. Predetermined Vth for enhancement are simultaneously achieved by a shift of a flatband voltage produced between the gate insulating film and the gate electrode made of the semiconductor film. Since a variation in Vth due to a statistical fluctuation in the number of impurities with respect to one MISFET can be reduced as compared with the case in which each Vth is controlled by the impurity concentration, Vth and a power supply voltage can both be set low.

    摘要: A first object of the present invention is to provide an insulated gate field effect transistor which realizes reductions in the junction depth and the resistance of source and drain junction regions beneath a gate electrode. Another object is to provide a miniaturized complementary type insulated gate field effect transistor capable of achieving a large current and a high operation speed. In a miniaturized MOS transistor, a low concentration impurity integrated layer comprising In or Ga is provided so as to have a peak in the inside of high concentration shallow source and drain diffusion layer regions. By this arrangement, the shallow source and drain diffusion layers are attracted by the impurity integrated layer, to realize shallower junctions having a high concentration and a rectangular distribution. As a result, particularly, a miniaturized PMOS with a larger current, punch-through hard and an ultra miniaturized configuration is achieved, and this can be applied also to NMOS, and, therefore, a CMOS with a larger current, punch-through hard and a more miniaturized configuration can be achieved without complicating the fabrication steps, namely, economically.
