  • Patent number: 8373070
    Abstract: Disclosed is a metal structure of a multi-layer substrate, comprising a first metal layer and a dielectric layer. The first metal layer has an embedded base and a main body positioned on the embedded base. The base area of the embedded base is larger than the base area of the main body. After the dielectric layer covers the main body and the embedded base, the dielectric layer is opened at the specific position of the first metal layer for connecting the first metal layer with a second metal layer above the dielectric layer. When the metal structure is employed as a pad or a metal line of the flexible multi-layer substrate according to the present invention, the metal structure cannot easily be delaminated or separated from the contacted dielectric layer. Therefore, a higher reliability for the flexible multi-layer substrate can be achieved.

  • Patent number: 8294039
    Abstract: A surface finish structure of multi-layer substrate and manufacturing method thereof. The surface finish structure of the present invention includes a bond pad layer, at least one cover metal layer and a solder mask. The cover metal layer covers the bond pad layer. The solder mask has a hole to expose the cover metal layer. The present invention can form the cover metal layer to cover the bond pad layer and then forms the solder mask. Thereafter, the hole is made to the solder mask at the position of the cover metal layer to expose thereof. Because the bond pad layer is embedded in a dielectric layer of the multi-layer substrate, adhesion intensity between the bond pad layer and the dielectric layer can be enhanced. Meanwhile, contact of the bond pad layer with the solder can be prevented with the cover metal layer.

By employing a carrier to alternately form dielectric layers and metal structure layers thereon. Each dielectric layer adheres with the adjacent dielectric layer to embed the metal structure layers in the dielectric layers corresponding thereto. Comparing with prior arts, which have to use prepregs when hot pressing and adhering different layers of different materials, the present invention takes fewer processes, thus, fewer kinds of materials without using prepregs. Therefore, the present invention can promote the entire quality and yield of manufacturing the multi-layer substrate to satisfy mechanical characteristic matching of the multi-layer substrate and to reduce cost of the whole manufacturing process.
