Abstract:
1. A three-dimensional die-stacking package structure, at least comprising a first die, a second die stacked under said first die and a conductive contact passing through said first die and said second die, wherein said first die at least has a first insulating layer and a first conductive contact pad, said first insulating layer is formed on an upper surface of said first die and on a surrounding wall of a part of said conductive contact, which passes through said first die, and said first conductive contact pad is integrally formed on a top end of said conductive contact; and a said second die at least has a second insulating layer and a second conductive contact pad, wherein said second insulating layer is formed on a surface of said second die opposite to said first die and on a surrounding wall of a part of said conductive contact, which passes through said second die, and said second conductive contact pad is formed integrally with a portion of said conductive contact, which is formed between said first die and said second die.
