Claim 14:
15. A manufacturing method of a package structure, comprising:
forming a thermal dissipation structure, comprising:
providing a semiconductor substrate having first conductive vias and second conductive vias embedded therein;
forming capacitors over the semiconductor substrate, wherein the capacitors are electrically connected to the first conductive vias and the second conductive vias;
forming a thermal transmission structure over the semiconductor substrate, the first conductive vias, and the second conductive vias, wherein the thermal transmission structure comprises a first conductive plane;
forming first bonding vias over the first conductive vias and second bonding vias over the second conductive vias; and
forming bonding pads on the first bonding vias and the second bonding vias, wherein the first conductive plane is in physical contact with sidewalls of at least one of the bonding pads;

hybrid bonding a first semiconductor die to the bonding pads of the thermal dissipation structure; and
hybrid bonding a second semiconductor die to the first semiconductor die opposite to the thermal dissipation structure.
