Abstract:
The present disclosure relates to a substrate structure with selective surface finishes used in flip chip assembly, and a process for making the same. The disclosed substrate structure includes a substrate body, a metal structure with a first finish area and a second finish area, a first surface finish, and a second surface finish. The metal structure is formed on a top surface of the substrate body, the first surface finish is formed over the first finish area of the metal structure, and the second surface finish is formed over the second finish area of the metal structure. The first surface finish is different from the second surface finish.

Claim (Index 1):
A method comprising:\n providing a substrate body with a first metal structure and a second metal structure formed on a top surface of the substrate body, wherein the first metal structure has a first finish area and the second metal structure has a second finish area; forming a first surface finish over at least one portion of the first finish area; forming a second surface finish over at least one portion of the second finish area, wherein the second surface finish has a different surface activity compared to the first surface finish; applying a flux material to the top surface of the substrate body to cover the first metal structure with the first surface finish and the second metal structure with the second surface finish; and coupling a flip chip die to the first finish area and the second finish area, wherein:\n the flip chip die includes a die body, a first interconnect structure, and a second interconnect structure; and \n the first interconnect structure extends from the die body toward the first finish area, and the second interconnect structure extends from the die body toward the second finish area.
