    摘要: In a replacement gate approach for forming high-k metal gate electrode structures, electronic fuses may be provided on the basis of a semiconductor material in combination with a metal silicide by using a recessed surface topography and/or a superior selectivity of the metal silicide material during the replacement gate process. For example, in some illustrative embodiments, electronic fuses may be provided in a recessed portion of an isolation region, thereby avoiding the removal of the semiconductor material when replacing the semiconductor material of the gate electrode structures with a metal-containing electrode material. Consequently, the concept of well-established semiconductor-based electronic fuses may be applied together with sophisticated replacement gate structures of transistors.

    摘要: 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.

    摘要: Dielectric cap layers of sophisticated high-k metal gate electrode structures may be efficiently removed on the basis of a sacrificial fill material, thereby reliably preserving integrity of a protective sidewall spacer structure, which in turn may result in superior uniformity of the threshold voltage of the transistors. The sacrificial fill material may be provided in the form of an organic material that may be reduced in thickness on the basis of a wet developing process, thereby enabling a high degree of process controllability.

    摘要: The method described herein involves a method of forming metal gates and metal contacts in a common fill process. 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.
