Abstract:
A method for forming an interconnect substrate, said method comprising:providing a transparent handle substrate; forming a adhesive photo-decomposing dielectric layer on said handle substrate; forming a multi-level interconnect structure having a plurality of bonding pads thereon on said adhesive photo-decomposing dielectric layer; applying an adhesive bonding film on said multi-level interconnect structure; patterning said adhesive bonding film to expose said bonding pads of said multi-level interconnect structure; providing a carrier substrate having a plurality of conductors thereon; bonding said multi-level interconnect structure with said carrier substrate by soldering said bonding pads to said conductors on said carrier substrate; decomposing said photo-decomposing dielectric layer; removing said handle substrate; and removing said photo-decomposing dielectric layer.
