    摘要: Operation of complex integrated circuits at low temperatures may be enhanced by providing active heating elements within the integrated circuit so as to raise the temperature of at least critical circuit portions at respective operational phases, such as upon power-up. Consequently, enhanced cold temperature performance may be obtained on the basis of existing process elements in order to provide design stability without requiring extensive circuit simulation or redesign of well-established circuit architectures.

    摘要: By forming an additional doped region with increased junction depth at areas in which contact regions may connect to drain and source regions, any contact irregularities may be embedded into the additional doped region, thereby reducing the risk for leakage currents or short circuits between the drain and source region and the well region that may be conventionally caused by the contact irregularity. Moreover, additionally or alternatively, the surface topography of the semiconductor region and the adjacent isolation trench may be modified prior to the formation of metal silicide regions and contact plugs to enhance the lithography procedure for forming respective contact openings in an interlayer dielectric material. For this purpose, the isolation trench may be brought to an equal or higher level compared to the adjacent semiconductor region.

    摘要: Generally, the present disclosure is directed to a method of removing “weakened” areas of a metal silicide layer during silicide layer formation, thereby reducing the likelihood that material defects might occur during subsequent device manufacturing. One illustrative embodiment includes depositing a first layer of a refractory metal on a surface of a silicon-containing material, and performing first and second heating processes. The method further comprises performing a cleaning process, depositing a second layer of the refractory metal above the silicon-containing material, and performing a third heating process.

    摘要: By selectively providing a buffer layer having an appropriate thickness, height differences occurring during the deposition of an SACVD silicon dioxide may be reduced during the formation of an interlayer dielectric stack of advanced semiconductor devices. The buffer material may be selectively provided after the deposition of contact etch stop layers of both types of internal stress or may be provided after the deposition of one type of dielectric material and may be used during the subsequent patterning of the other type of dielectric stop material as an efficient etch stop layer.

    摘要: In sophisticated semiconductor devices, stress-inducing materials may be provided above the basic transistor devices without any etch control or etch stop materials, thereby enabling an efficient de-escalation of the surface topography, in particular above field regions including closely spaced polysilicon lines. Furthermore, an additional stress-inducing material may be provided on the basis of the superior surface topography, thereby providing a highly efficient strain-inducing mechanism in performance-driven transistor elements.
