Abstract:
1. A three-dimensional stacking dice package structure, at least comprising: a first substrate having a first surface and a second surface opposite to said first surface, including: a second substrate having a first surface and a second surface opposite to said first surface, including: at least one conductive bump formed to stack said first substrate and said second substrate; wherein, at said second surface of said first substrate, said conductive bump completely covers the portion of said first conductive layer extending from said through hole and covering a surface of said insulating layer and the portion of said second conductive layer extending from said through hole and covering a surface of said first conductive layer; and wherein, at said first surface of said second substrate, said conductive bump completely covers the portion of said first conductive layer extending from said through hole and covering a surface of said insulating layer and the portion of said second conductive layer extending from said through hole and covering a surface of said first conductive layer.
