CMOS STRUCTURE HAVING LOW RESISTANCE CONTACTS AND FABRICATION METHOD |
摘要 |
A method for fabricating a CMOS integrated circuit structure and the CMOS integrated circuit structure. The method includes creating one or more n-type wells, creating one or more p-type wells, creating one or more pFET source-drains embedded in each of the one or more n-type wells, creating one or more nFET source-drains embedded in each of the one or more p-type wells, creating a pFET contact overlaying each of the one or more pFET source-drains, and creating an nFET contact overlaying each of the one or more nFET source-drains. A material of each of the one or more pFET source-drains includes silicon doped with a p-type material; a material of each of the one or more nFET source-drains includes silicon doped with an n-type material; a material of each pFET contact includes nickel silicide; and a material of each nFET contact comprises titanium silicide. |

creating one or more n-type wells; creating one or more p-type wells; creating one or more pFET source-drains embedded in and overlaying each of the one or more n-type wells,
wherein a material of each of the one or more pFET source-drains comprises silicon doped with a p-type material; creating one or more nFET source-drains embedded in and overlaying each of the one or more p-type wells,
wherein a material of each of the one or more nFET source-drains comprises silicon doped with an n-type material; creating a pFET contact overlaying each of the one or more pFET source-drains,
wherein a material of each pFET contact comprises nickel silicide; and creating an nFET contact overlaying each of the one or more nFET source-drains,
wherein a material of each nFET contact comprises titanium silicide. |
