    摘要: The polysilicon gate electrode of a MOS transistor may be substantially completely converted into a metal silicide without sacrificing the drain and source junctions in that a thickness of the polysilicon layer, for forming the gate electrode, is targeted to be substantially converted into metal silicide in a subsequent silicidation process. The gate electrode, substantially comprised of metal silicide, offers high conductivity even at critical dimensions in the deep sub-micron range, while at the same time the effect of polysilicon gate depletion is significantly reduced. Manufacturing of the MOS transistor, having the substantially fully-converted metal silicide gate electrode, is essentially compatible with standard MOS process technology.

    摘要: According to one illustrative embodiment of the present invention, a method of forming a field effect transistor includes the formation of a doped high-k dielectric layer above a substrate including a gate electrode formed over an active region and separated therefrom by a gate insulation layer. A heat treatment is carried out with the substrate to diffuse dopants from the high-k dielectric layer into the active region to form extension regions. The high-k dielectric layer is patterned to form sidewall spacers at sidewalls of the gate electrode and an implantation process is carried out with the sidewall spacers as implantation mask to form source and drain regions.

    摘要: By forming bulk-like transistors in sensitive RAM areas of otherwise SOI-based CMOS circuits, a significant savings in valuable chip area may be achieved since the RAM areas may be formed on the basis of a bulk transistor configuration, thereby eliminating hysteresis effects that may typically be taken into consideration by providing transistors of increased transistor width or by providing body ties. Hence, the benefit of high switching speed may be maintained in speed-critical circuitry, such as CPU cores, while at the same time the RAM circuit may be formed in a highly space-efficient manner.

    摘要: The present invention allows the manufacturing of field effect transistors with reduced thermal budget. A first amorphized region and a second amorphized region are formed in a substrate adjacent to the gate electrode by implanting ions of a non-doping element, the presence of which does not significantly alter the conductive properties of the substrate. The formation of the amorphized regions may be performed before or after the formation of a source region, a drain region, an extended source region and an extended drain region. The substrate is annealed to achieve solid phase epitaxial regrowth of the amorphized regions and to activate dopants in the source region, the drain region, the extended source region and the extended drain region.

    摘要: A method is disclosed in which a lightly doped region in a semiconductor layer is obtained by diffusing dopant atoms of a first and second type into the underlying semiconductor layer. Preferably, the method is applied to the formation of lightly doped source and drain regions in a field effect transistor so as to obtain a required gradual dopant concentration transition from the general region to the drain and source regions for avoiding the hot carrier effect. Advantageously, a diffusion of the dopant atoms is initiated during an oxidizing step in which the thickness of the gate insulation layer is increased at the edge portions thereof.
