摘要:
Deep drain and source regions of an N-channel transistor may be formed through corresponding cavities, which may be formed together with cavities of a P-channel transistor, wherein the lateral offsets of the cavities may be adjusted on the basis of an appropriate reverse spacer regime. Consequently, the dopant species in the N-channel transistor extends down to a specific depth, for instance down to the buried insulating layer of an SOI device, while at the same time providing an efficient strain-inducing mechanism for the P-channel transistor with a highly efficient overall manufacturing process flow.
摘要:
Non-planar transistors, such as FINFETs, may be formed on the basis of a globally strained semiconductor material, thereby preserving a high uniaxial strain component in the resulting semiconductor fins. In this manner, a significant performance enhancement may be achieved without adding process complexity when implementing FINFET transistors.
摘要:
In a semiconductor device, optical signal transfer capabilities are implemented on the basis of silicon-based monolithic opto-electronic components in combination with an appropriate waveguide. Thus, in complex circuitries, such as microprocessors and the like, superior performance may be obtained in terms of signal propagation delay, while at the same time thermal requirements may be less critical.

摘要:
In sophisticated transistor elements, enhanced profile uniformity along the transistor width direction may be accomplished by using a gate material in an amorphous state, thereby reducing channeling effects and line edge roughness. In sophisticated high-k metal gate approaches, an appropriate sequence may be applied to avoid a change of the amorphous state prior to performing the critical implantation processes for forming drain and source extension regions and halo regions.
摘要:
When forming high-k metal gate electrode structures in an early manufacturing stage, integrity of an encapsulation and, thus, integrity of sensitive gate materials may be improved by reducing the surface topography of the isolation regions. To this end, a dielectric cap layer of superior etch resistivity is provided in combination with the conventional silicon dioxide material.

摘要:
In a replacement gate approach in sophisticated semiconductor devices, the place-holder material of gate electrode structures of different type are separately removed. Furthermore, electrode metal may be selectively formed in the resulting gate opening, thereby providing superior process conditions in adjusting a respective work function of gate electrode structures of different type. In one illustrative embodiment, the separate forming of gate openings in gate electrode structures of different type may be based on a mask material that is provided in a gate layer stack.
