Die configurations and methods of manufacture
View Patent ↗A die configuration includes a die having an active side and an inactive side being opposed to the active side. The inactive side is connected to a heat sink. The connecting members can be provided on the active side.
1. A die configuration, comprising:
a die;
mold material around the die;
one side of the die comprising die pad regions;
die configuration connecting members; and
die connecting members connecting the die configuration connecting members to the die pad regions through the mold material, each die connecting member of the die connecting members being formed by a bump, the bump comprising a first partial bump and a second partial bump, the second partial bump having a different width than the first partial bump;
wherein the die configuration connecting members are located adjacent the second partial bump.
2. The die configuration of claim 1 , wherein the die has an active side and an inactive side being opposed to the active side, the die configuration further comprising a heat sink coupled to the inactive side.
3. The die configuration of claim 2 , wherein the heat sink comprises a metal plate.
4. The die configuration of claim 1 , wherein the die configuration connecting members comprise solder members.
5. The die configuration of claim 4 , wherein the solder members comprise ball grid array solder bumps.
6. The die configuration of claim 4 , wherein the solder members comprise lead-free solder members.
7. The die configuration of claim 1 , wherein the die pad regions are electrically coupled to electronic components of the die.
8. The die configuration of claim 1 , wherein the bump comprises a pillar bump.
9. The die configuration of claim 1 , wherein the bump comprises a metal bump.
10. The die configuration of claim 1 , wherein the bump comprises a copper bump.
11. The die configuration of claim 1 , wherein the second partial bump has a greater width than the first partial bump.
12. A die configuration, comprising:
a die having an active side and an inactive side opposed to the active side;
a thermal interface material layer on the inactive side of the die;
a metal plate adjacent the inactive side of the die, the thermal interface material layer between the metal plate and the die;
mold material around the die, at least partially exposing the metal plate;
die pad regions on the active side of the die; and
die connecting members connecting the die pad regions to die configuration pad regions through the mold material.
13. The die configuration of claim 12 , further comprising die configuration connecting members coupled to the die configuration pad regions.
14. The die configuration of claim 13 , wherein the die configuration connecting members comprise solder members.
15. The die configuration of claim 12 , further comprising a circuit board connected to the die configuration pad regions.
16. The die configuration of claim 15 , wherein the circuit board comprises a printed circuit board.
17. A die configuration, comprising:
a die;
a metal plate, a first side of the die being connected to the metal plate;
mold material around the die, at least partially exposing the metal plate;
a second side of the die being opposed to the first side of the die and comprising die pad regions;
die configuration connecting members;
die connecting members connecting the die configuration connecting members to the die pad regions through the mold material, wherein each die connecting member of the die connecting members includes a metal pillar bump, the pillar bump comprising a first partial bump and a second partial bump, the second partial bump having a greater width than the first partial bump, and
a printed circuit board connected to the die configuration pad regions;
wherein the die configuration connecting members are located on the second partial bump.
18. A die configuration, comprising
a die having an active side and an inactive side opposed to the active side;
a heat sink internally coupled to the inactive side of the die; and
a thermal interface material between the inactive side of the die and the heat sink;
mold material around the die, at least partially exposing the metal plate;
die pad regions on the active side of the die; and
die connecting members connecting the die pad regions to die configuration pad regions through the mold material.
19. The die configuration of claim 18 , wherein the heat sink comprises a metal heat sink.
20. The die configuration of claim 18 , further comprising die configuration connecting members coupled to the die configuration pad regions.
21. The die configuration of claim 20 , wherein the die configuration connecting members comprise solder members.
22. The die configuration of claim 18 , further comprising a circuit board connected to the die configuration pad regions.
23. The die configuration of claim 22 , wherein the circuit board comprises a printed circuit board.
