A surface tension-reducing layer is disposed between the source or drain region of the PMOS transistor and an overlying surface tension-inducing layer. The surface tension-inducing layer may comprise a nitride material or carbon-containing material, and the surface tension-reducing layer may comprise an oxide material. Degradation of hole mobility in the PMOS transistor is prevented by the use of the surface tension-reducing layer of the bilayer etch stop.

    摘要: A method for performing a stress memorization technique (SMT) a FinFET and a FinFET having memorized stress effects including multi-planar dislocations are disclosed. An exemplary embodiment includes receiving a FinFET precursor with a substrate, a fin structure on the substrate, an isolation region between the fin structures, and a gate stack over a portion of the fin structure. The gate stack separates a source region of the fin structure from a drain region of the fin structure and creates a gate region between the two. The embodiment also includes forming a stress-memorization technique (SMT) capping layer over at least a portion of each of the fin structures, isolation regions, and the gate stack, performing a pre-amorphization implant on the FinFET precursor by implanting an energetic doping species, performing an annealing process on the FinFET precursor, and removing the SMT capping layer.

    摘要: An apparatus for characterizing capacitance and thickness of an insulating layer constructed between a conductive gate and a substrate has at least one test structure formed at a surface of a substrate. Each test structure has a bulk region formed of a semiconductor within the surface. Further the test structure has at least one source region and one drain region within the bulk region. A thin insulating layer is placed above the each source region, each drain region, and the bulk region. A conductive gate is placed above the thin insulating layer. A capacitance-voltage measuring device measures a capacitance value of the test structure, while forcing the bulk region between the source region and the drain region to be floating. An insulating layer thickness calculator determines the thickness of the insulating layer from the capacitance.

    摘要: A process for fabricating a MOSFET device featuring a channel region comprised with a silicon-germanium component is provided. The process features employ an angled ion implantation procedure to place germanium ions in a region of a semiconductor substrate underlying a conductive gate structure. The presence of raised silicon shapes used as a diffusion source for a subsequent heavily-doped source/drain region, the presence of a conductive gate structure, and the removal of dummy insulator previously located on the conductive gate structure allow the angled implantation procedure to place germanium ions in a portion of the semiconductor substrate to be used for the MOSFET channel region. An anneal procedure results in the formation of the desired silicon-germanium component in the portion of semiconductor substrate to be used for the MOSFET channel region.
