METHODS FOR FABRICATING INTEGRATED CIRCUITS HAVING SUBSTRATE CONTACTS AND INTEGRATED CIRCUITS HAVING SUBSTRATE CONTACTS
摘要:
Methods for fabricating integrated circuits having substrate contacts and integrated circuits having substrate contacts are provided. One method includes forming a first trench in a SOI substrate extending through a buried insulating layer to a silicon substrate. A metal silicide region is formed in the silicon substrate exposed by the first trench. A first stress-inducing layer is formed overlying the metal silicide region. A second stress-inducing layer is formed overlying the first stress-inducing layer. An ILD layer of dielectric material is formed overlying the second stress-inducing layer. A second trench is formed extending through the ILD layer and the first and second stress-inducing layers to the metal silicide region. The second trench is filled with a conductive material.
