Abstract: When forming sophisticated P-channel transistors, a semiconductor alloy layer is formed on the surface of the semiconductor layer including the transistor active region. When a metal silicide layer is formed contiguous to this semiconductor alloy layer, an agglomeration of the metal silicide layer into isolated clusters is observed. In order to solve this problem, the present invention proposes a method and a semiconductor device wherein the portion of the semiconductor alloy layer lying on the source and drain regions of the transistor is removed before formation of the metal silicide layer is performed. In this manner, the metal silicide layer is formed so as to be contiguous to the semiconductor layer, and not to the semiconductor alloy layer.

Abstract: Upon forming a complex metallization system, the parasitic capacitance between metal lines of adjacent metallization layers may be reduced by providing a patterned etch stop material. In this manner, the patterning process for forming the via openings may be controlled in a highly reliable manner, while, on the other hand, the resulting overall dielectric constant of the metallization system may be reduced, thereby also significantly reducing the parasitic capacitance between stacked metal lines.

Abstract: The present disclosure provides manufacturing techniques and semiconductor devices in which performance of P-channel transistors may be enhanced on the basis of a stress mechanism that involves the deposition of a dielectric bi-layer system.

The method may involve forming a gate structure comprising a sacrificial gate electrode material, forming at least one conductive contact opening in a layer of insulating material positioned adjacent the gate structure, removing the sacrificial gate electrode material to thereby define a gate electrode opening, and performing a common deposition process to fill the conductive contact opening and the gate electrode opening with a conductive fill material.

Abstract: In sophisticated semiconductor devices comprising high-k metal gate electrode structures formed on the basis of a replacement gate approach, semiconductor-based resistors may be provided without contributing to undue process complexity in that the resistor region is recessed prior to depositing the semiconductor material of the gate electrode structure. Due to the difference in height level, a reliable protective dielectric material layer is preserved above the resistor structure upon exposing the semiconductor material of the gate electrode structure and removing the same on the basis of selective etch recipes. Consequently, well-established semiconductor materials, such as polysilicon, may be used for the resistive structures in complex semiconductor devices, substantially without affecting the overall process sequence for forming the sophisticated replacement gate electrode structures.
