摘要:
In sophisticated semiconductor devices, stress memorization techniques may be applied on the basis of a silicon nitride material, which may be subsequently modified into a low-k dielectric material in order to obtain low-k spacer elements, thereby enhancing performance of sophisticated semiconductor devices. The modification of the initial silicon nitride-based spacer material may be accomplished on the basis of an oxygen implantation process.
摘要:
In a replacement gate approach, the semiconductor material or at least a significant portion thereof in a non-transistor structure, such as a precision resistor, an electronic fuse and the like, may be preserved upon replacing the semiconductor material in the gate electrode structures. To this end, an appropriate dielectric material may be provided at least prior to the removal of the semiconductor material in the gate electrode structures, without requiring significant modifications of established replacement gate approaches.
摘要:
A semiconductor-based electronic fuse may be provided in a sophisticated semiconductor device having a bulk configuration by appropriately embedding the electronic fuse into a semiconductor material of reduced heat conductivity. For example, a silicon/germanium fuse region may be provided in the silicon base material. Consequently, sophisticated gate electrode structures may be formed on the basis of replacement gate approaches on bulk devices substantially without affecting the electronic characteristics of the electronic fuses.
摘要:
In sophisticated semiconductor devices, electronic fuses may be provided on the basis of a replacement gate approach by using the aluminum material as an efficient metal for inducing electromigration in the electronic fuses. The electronic fuse may be formed on an isolation structure, thereby providing an efficient thermal decoupling of the electronic fuse from the semiconductor material and the substrate material, thereby enabling the provision of efficient electronic fuses in a bulk configuration, while avoiding incorporation of fuses into the metallization system.

摘要:
In sophisticated semiconductor devices including transistors having a high-k metal gate electrode structure, disposable spacers may be provided on the encapsulating spacer element with a reduced width so as to not unduly increase a lateral offset of a strain-inducing material to be incorporated into the active region. For this purpose, a multi-layer deposition may be used in combination with a low pressure CVD process.
摘要:
Semiconductor devices are formed with reduced variability between close proximity resistors, improved end resistances, and reduced random dopant mismatch. Embodiments include ion implanting a dopant, such as B, at a relatively high dosage, e.g. about 4 to about 6 keV, and at a relatively low implant energy, e.g., about 1.5 to about 2E15/cm2.
