  • MOS transistors with improved gate dielectrics
    Patent number: 6590241
    Abstract: The specification describes silicon MOS devices with gate dielectrics having the composition Ta1−xAlxOy, where x is 0.03-0.7 and y is 1.5-3, Ta1−xSixOy, where x is 0.05-0.15, and y is 1.5-3, and Ta1−x−zAlxSizOy, where 0.7>x+z>0.05, z<0.15 and y is 1.5-3. By comparison with the standard SiO2 gate dielectric material, these materials provide improved dielectric properties and also remain essentially amorphous to high temperatures. This retards formation of SiO2 interfacial layers which otherwise dominate the gate dielectric properties and reduce the overall effectiveness of using a high dielectric material.
    Type: Grant
    Filed: March 7, 2000
    Date of Patent: July 8, 2003
    Assignee: Agere Systems Inc.

  • MOS transistors with improved gate dielectrics
    Patent number: 6060406
    Abstract: The specification describes silicon MOS devices with gate dielectrics having the composition Ta.sub.1-x Al.sub.x O.sub.y, where x is 0.03-0.7 and y is 1.5-3, Ta.sub.1-x Si.sub.x O.sub.y, where x is 0.05-0.15, and y is 1.5-3, and Ta.sub.1-x-z Al.sub.x Si.sub.z O.sub.y, where 0.7>x+z>0.05, z<0.15 and y is 1.5-3. By comparison with the standard SiO.sub.2 gate dielectric material, these materials provide improved dielectric properties and also remain essentially amorphous to high temperatures. This retards formation of SiO.sub.2 interfacial layers which otherwise dominate the gate dielectric properties and reduce the overall effectiveness of using a high dielectric material.
