    摘要: A strain-induced layer is formed atop a MOS device in order to increase carrier mobility in the channel region. The dimension of the strain-induced layer in preferred embodiments may lead to an optimized drive current increase and improved drive current uniformity in an NMOS and PMOS device. An advantage of the preferred embodiments is that improved device performance is obtained without adding complex processing steps. A further advantage of the preferred embodiments is that the added processing steps can be readily integrated into a known CMOS process flow. Moreover, the creation of the photo masks defining the tensile and compressive strain-induced layers does not require extra design work on an existed design database.

    摘要: A method for forming a semiconductor structure includes providing a substrate, forming a first device region on the substrate, forming a stressor layer overlying the first device region, and super annealing the stressor layer in the first device region, preferably by exposing the substrate to a high-energy radiance source, so that the stressor layer is super annealed for a substantially short duration. Preferably, the method further includes masking a second device region on the substrate while the first device region is super annealed. Alternatively, after the stressor layer in the first region is annealed, the stressor layer in the second device region is super annealed. A semiconductor structure formed using the method has different strains in the first and second device regions.

    摘要: A method for fabricating a dual-gate semiconductor device. A preferred embodiment comprises forming a gate stack having a first portion and a second portion, the first portion and the second portion including a different composition of layers, forming photoresist structures on the gate stack to protect the material to be used for the gate structures, etching away a portion of the unprotected material, forming recesses adjacent to at least one of the gate structures in the substrate upon which the gate structures are disposed, and forming a source region and the drained region in the respective recesses. The remaining portions of the gate stack layers that are not a part of a gate structure are then removed. In a particularly preferred embodiment, an oxide is formed on the vertical sides of the gate structures prior to etching to create the source and drain regions.
