Self-aligned interconnect features for transistor contacts
An integrated circuit includes (i) a first transistor device having a first source or drain region coupled to a first source or drain contact, and a first gate electrode, (ii) a second transistor device having a second source or drain region coupled to a second source or drain contact, and a second gate electrode, (iii) a first dielectric material above the first and second source or drain contacts, (iv) a second dielectric material above the first and second gate electrodes, (v) a third dielectric material above the first and second dielectric materials, and (vi) an interconnect feature above and conductively coupled to the first source or drain contact. In an example, the interconnect feature comprises an upper body of conductive material extending within the third dielectric material, and a lower body of conductive material extending within the first dielectric material, with an interface between the upper and lower bodies.
