Claim 0:
1. A method for manufacturing a substrate structure with high reflectance, comprising:
providing a base material;
forming a first patterned circuit layer and a second patterned circuit layer on a first surface and a second surface of the base material;
providing a first insulation layer and a metal reflection layer on the first patterned circuit layer and a portion of the first surface exposed by the first patterned circuit layer, wherein the metal reflection layer covers the first insulation layer, and a reflectance of the metal reflection layer is substantially greater than or equal to 85%, there is no conductive material between the first patterned circuit layer and the metal reflection layer; and
forming a first ink layer on the first insulation layer before the metal reflection layer is formed.
