    摘要: There is provided a semiconductor device comprising an insulating layer which is partly formed of porous material, and a method for fabricating the device. A stray capacitance of adjacent wiring lines is significantly reduced by reducing the amount of material, i.e., by using porous material in the insulating layer of a metallization layer. In one embodiment, the porous layer may be fabricated separately on a further substrate and is subsequently transferred to the product wafer while the further substrate and the product wafer are appropriately aligned to each other. In this way, fabrication of complete metallization layers having a reduced dielectric constant in advance or concurrently with the product wafer carrying the MOS structure is possible. Due to the reduced capacitance of the wiring lines of the metallization layer, signal performance and/or power consumption of an integrated circuit is improved.

    摘要: A method is disclosed in which differing metal layers are sequentially deposited on silicon-containing regions so that the type and thickness of the metal layers may be adapted to specific characteristics of the underlying silicon-containing regions. Subsequently, a heat treatment is performed to convert the metals into metal silicides so as to improve the electrical conductivity of the silicon-containing regions. In this way, silicide portions may be formed that are individually adapted to specific silicon-containing regions so that device performance of individual semiconductor elements or the overall performance of a plurality of semiconductor elements may significantly be improved. Moreover, a semiconductor device is disclosed comprising at least two silicon-containing regions having formed therein differing silicide portions, wherein at least one silicide portion comprises a noble metal.

    摘要: A transistor formed on a substrate comprises a gate electrode having a lateral extension at the foot of the gate electrode that is less than the average lateral extension of the gate electrode. The increased cross-section of the gate electrode compared to the rectangular cross-sectional shape of a prior art device provides for a significantly reduced gate resistance while the effective gate length, i.e., the lateral extension of the gate electrode at its foot, may be scaled down to a size of 100 nm and beyond. Moreover, a method for forming the field effect transistor described above is disclosed.

    摘要: An epitaxially grown channel layer is provided on a well structure after ion implantation steps and heat treatment steps are performed to establish a required dopant profile in the well structure. The channel layer may be undoped or slightly doped, as required, so that the finally obtained dopant concentration in the channel layer is significantly reduced compared to a conventional device to thereby provide a retrograde dopant profile in a channel region of a field effect transistor. Additionally, a barrier diffusion layer may be provided between the well structure and the channel layer to reduce up-diffusion during any heat treatments carried out after the formation of the channel layer. The final dopant profile in the channel region may be adjusted by the thickness of the channel layer, the thickness and the composition of the diffusion barrier layer and any additional implantation steps to introduce dopant atoms in the channel layer.
