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 8):
The method according to  claim 1  wherein said plating said copper traces comprises electrolytically plating copper to a thickness of between about 2 to 18 \u03bcm wherein a ratio of the top to bottom widths of said copper traces is close to 1, wherein an elongation strength of said copper traces is over 15%, wherein a tensile strength of said copper traces is between about 290 and 340 N/mm 2 , and wherein a hardness of said copper traces is 100 in vicker hardness with a purity of more than 99.9%.
