High density multichip module packaging structure |
摘要 |
A multichip module packaging structure provided over a mother board. A multichip module substrate is mounted over the mother board through a frame member. The frame member is provided to extend successively on a peripheral region of a bottom surface of the substrate and further extend downward from the bottom surface of the substrate. The frame member also has a top portion bonded with the bottom surface of the substrate and a bottom portion bonded with the top surface of the mother substrate so as to form a three dimensional space surrounded by the frame member, the substrate and the mother board. A plurality of semiconductor integrated circuit chips are provided on the bottom surface of the substrate so that the chips are accommodated within the three dimensional space.
