Abstract:
The present disclosure provides a semiconductor structure, including providing a metal layer, an adhesion-enhancing layer over the metal layer, a dielectric stack over the adhesion-enhancing layer, a contact penetrating the dielectric stack and the adhesion-enhancing layer and connecting with the metal layer, a barrier layer disposed between the contact and the dielectric stack, and a high-k dielectric layer disposed between the contact and the barrier layer.

Claim (Index 14):
A method for forming a semiconductor structure, comprising:\n forming a metal layer; forming an adhesion-enhancing layer over the metal layer by a silicide operation; forming a dielectric stack over the adhesion-enhancing layer; forming a trench in the dielectric stack by removing a portion of dielectric stack aligning with the metal layer; forming a barrier layer conforming to the sidewall of the trench; forming a high-k dielectric layer conforming to the barrier layer; and forming a contact in the trench and connecting to the metal layer.
