Semiconductor devices and conductive structures can be formed having a metallic layer. In one embodiment, a semiconductor device includes an amorphous metallic layer (22) and a crystalline metallic layer (42). The amorphous metallic layer (22) helps to reduce the likelihood of penetration of contaminants through the amorphous metallic layer (22). A more conductive crystalline metallic layer (42) can be formed on the amorphous metallic layer (22) to help keep resistivity relatively low. When forming a conductive structure, a metal-containing gas and a scavenger gas flow simultaneously during at least one point in time. The conductive structure may be part of a gate electrode.

摘要:
A method for forming a metal gate (20) structure begins by providing a semiconductor substrate (12). The semiconductor substrate (12) is cleaned to reduce trap sites. A nitrided layer (14) having a thickness of less than approximately 20 Angstroms is formed over the substrate (12). This nitrided layer prevents the formation of an oxide at the substrate interface and has a dielectric constant greater than 3.9. After the formation of the nitrided layer(14), a metal oxide layer (16) having a permittivity value of greater than roughly 8.0 is formed over the nitrided layer (14). A metal gate (20) is formed over the nitrided layer whereby the remaining composite gate dielectric (14 and 16) has a larger physical thickness but a high-performance equivalent oxide thickness (EOT).
