Abstract:
A method to produce a substrate suitable for diffusion bonding is described. A flexible dielectric substrate is provided. An alkaline modification is applied to the dielectric substrate to form a polyamic acid (PAA) anchoring layer on a surface of the dielectric substrate. A Ni—P seed layer is electrolessly plated on the PAA layer. Copper traces are plated within a photoresist pattern on the Ni—P seed layer. A surface finishing layer is electrolytically plated on the copper traces. The photoresist pattern and Ni—P seed layer not covered by the copper traces are removed to complete the substrate suitable for diffusion bonding.

Claim (Index 10):
A method of manufacturing a flexible substrate comprising:\n providing a flexible dielectric substrate; laser drilling at least one first via opening all the way through said dielectric substrate; applying an alkaline modification to said dielectric substrate to form a first polyamic acid (PAA) anchoring layer on top and bottom surfaces of said dielectric substrate; electrolessly plating a first Ni\u2014P seed layer on top and bottom of said first PAA layers; forming a first photoresist pattern on top and bottom of said first Ni\u2014P seed layers; plating first copper traces within said first photoresist patterns and through said at least one first via opening; plating a surface finishing layer on said first copper traces; and removing said first photoresist patterns and etching away said first Ni\u2014P seed layers not covered by said first copper traces to complete said flexible substrate.
