Abstract: Storage transistors for flash memory areas in semiconductor devices may be provided on the basis of a self-aligned charge storage region. To this end, a floating spacer element may be provided in some illustrative embodiments, while, in other cases, the charge storage region may be efficiently embedded in the electrode material in a self-aligned manner during a replacement gate approach. Consequently, enhanced bit density may be achieved, since additional sophisticated lithography processes for patterning the charge storage region may no longer be required.

Abstract: In sophisticated semiconductor devices, replacement gate approaches may be applied in combination with a process strategy for implementing a strain-inducing semiconductor material, wherein superior proximity of the strain-inducing semiconductor material and/or superior robustness of the replacement gate approach may be achieved by forming the initial gate electrode structures with superior uniformity and providing at least one cavity for implementing the strained channel regions in a very advanced manufacturing stage, i.e., after completing the basic transistor configuration.

Abstract: Electron mobility and hole mobility is improved in long channel semiconductor devices and resistors by employing complementary stress liners. Embodiments include forming a long channel semiconductor device on a substrate, and forming a complementary stress liner on the semiconductor device. Embodiments include forming a resistor on a substrate, and tuning the resistance of the resistor by forming a complementary stress liner on the resistor.

Abstract: Performance and/or uniformity of sophisticated transistors may be enhanced by incorporating a carbon species in the active regions of the transistors prior to forming complex high-k metal gate electrode structures. For example, a carbon species may be incorporated by ion implantation into the active region of a P-channel transistor and an N-channel transistor after selectively forming a threshold adjusted semiconductor material for the P-channel transistor, while the active region of the N-channel transistor is still masked.

Abstract: Methods are provided for fabricating an integrated circuit that includes gate to active contacts. One method includes forming a dummy gate structure including a dummy gate electrode having sidewalls and overlying a semiconductor substrate and first and second sidewall spacers on the sidewalls of the dummy gate electrode. The method includes removing the dummy gate electrode to form a trench bounded by the first and second sidewall spacers. The method removes an upper portion of the first sidewall spacer and deposits a layer of metal in the trench and over a remaining portion of the first sidewall spacer to form a gate electrode and an interconnect.

Abstract: Lithographic limitations on gate and induced channel length in MOSFETS are avoided by forming non-planar MOSFETS in a cavity extending into a semiconductor substrate. The gate insulator and channel region lie proximate a cavity sidewall having angle α preferably about ≧90 degrees with respect to the semiconductor surface. The channel length depends on the bottom depth of the cavity and the depth from the surface of a source or drain region adjacent the cavity. The corresponding drain or source lies at the cavity bottom. The cavity sidewall extends therebetween. Neither depth is lithographic dependent. Very short channels can be consistently formed, providing improved performance and manufacturing yield. Source, drain and gate connections are brought to the same surface so that complex circuits can be readily constructed. The source and drain regions are preferably formed epitaxially and strain inducing materials can be used therein to improve channel carrier mobility.
