    摘要: Apparatus for semiconductor device structures and related fabrication methods are provided. One method for fabricating a semiconductor device structure involves forming a layer of dielectric material overlying a doped region formed in a semiconductor substrate adjacent to a gate structure and forming a conductive contact in the layer of dielectric material. The conductive contact overlies and electrically connects to the doped region. The method continues by forming a second layer of dielectric material overlying the conductive contact, forming a voided region in the second layer overlying the conductive contact, forming a third layer of dielectric material overlying the voided region, and forming another voided region in the third layer overlying at least a portion of the voided region in the second layer. The method continues by forming a conductive material that fills both voided regions to contact the conductive contact.

    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: Memory cells in integrated circuit devices may be formed on the basis of functional molecules which may be positioned within via openings on the basis of appropriate patterning techniques, which may also be used for forming semiconductor-based integrated circuits. Consequently, memory cells may be formed on a “molecular” level without requiring extremely sophisticated patterning regimes, such as electron beam lithography and the like.
