Abstract:
Systems and methods are described for improved heat dissipation of the stacked semiconductor dies by including metallic thermal pads between the dies in the stack. In one embodiment, the thermal pads may be in direct contact with the semiconductor dies. Heat dissipation of the semiconductor die stack can be improved by a relatively high thermal conductivity of the thermal pads that directly contact the adjacent silicon dies in the stack without the intervening layers of the low thermal conductivity materials (e.g., passivation materials). In some embodiments, the manufacturing yield of the stack can be improved by having generally coplanar top surfaces of the thermal pads and under-bump metallization (UBM) structures.

Claim (Index 10):
A semiconductor die, comprising:\n a semiconductor substrate having a surface and an indentation in the surface; an interconnect extending at least partially through the semiconductor substrate, wherein the interconnect includes an end portion projecting from the indentation, and wherein the end portion has a sidewall exposed from the semiconductor substrate in the indentation; a metallization structure extending at least partially around the sidewall of the end portion of the interconnect; a passivation material at least partially on the surface of the semiconductor substrate, wherein a first portion of the passivation material is in the indentation between the metallization structure and the semiconductor substrate, and wherein a second portion of the passivation material is in the indentation and laterally spaced apart from the metallization structure; and a thermal pad on the surface of the semiconductor substrate, wherein the thermal pad and the metallization structure extend away from the surface of the semiconductor substrate to generally the same height.
