Die support for enlarging die size
View Patent ↗A chip package, in some embodiments, comprises: a die flag; one or more die supports; and a die mounted on the die flag and on said one or more die supports, at least one surface of said die having an area larger than an area of at least one surface of the die flag.
1. A chip package, comprising:
a die flag;
one or more electrical terminals;
one or more die supports physically separate from the one or more electrical terminals; and
a die mounted on the die flag and on said one or more die supports, the die electrically coupled to the one or more electrical terminals, at least one surface of said die having an area larger than an area of at least one surface of the die flag,
wherein at least one of the one or more die supports is non-conductive.
2. The chip package of claim 1 , wherein the one or more die supports at least partially surrounds the die flag in at least one plane.
3. The chip package of claim 1 , wherein each of the one or more die supports comprises a pair of segments, each segment in said pair runs parallel to a different edge of the die flag.
4. The chip package of claim 1 , wherein the one or more die supports comprises four die supports, each of the four die supports runs parallel to a different edge of the die flag.
5. The chip package of claim 1 , wherein the chip package is a leadless land grid array (LLGA) package.
6. A chip package, comprising:
one or more electrical terminals exposed to one or more outer surfaces of the chip package;
a die flag;
one or more die supports positioned between the die flag and the one or more electrical terminals in at least one plane, the one or more die supports physically separate from the one or more electrical terminals and from the die flag;
a die mounted on said die flag and on said one or more die supports; and
one or more electrical connections between the die and said one or more electrical terminals,
wherein at least one of the one or more die supports is non-conductive.
7. The chip package of claim 6 , wherein at least one of the one or more die supports comprises epoxy.
8. The chip package of claim 6 , wherein at least one of the one or more die supports is at least partially colored black.
9. The chip package of claim 6 , wherein said one or more die supports surrounds the die flag in at least one plane.
10. The chip package of claim 6 , wherein at least one of the one or more die supports contains multiple segments, each of said segments runs parallel to a different edge of the die flag.
11. The chip package of claim 6 , wherein at least one of the one or more die supports runs parallel to a single edge of the die flag.
12. The chip package of claim 6 , wherein the one or more electrical connections comprises wire bonds.
13. The chip package of claim 6 , wherein said chip package is a quad flat no-leads (QFN) package.
14. The chip package of claim 6 , wherein said chip package is a leadless land grid array (LLGA) package.
15. A method for manufacturing a chip package, comprising:
providing a carrier having a die flag formed thereupon;
positioning one or more die supports on said carrier;
mounting a die on said die flag and on the one or more die supports;
electrically coupling said die to one or more electrical terminals of the carrier, the one or more electrical terminals physically separate from the one or more die supports; and
encapsulating at least the die flag, the one or more die supports, and the die using a mold compound,
wherein at least one of the one or more die supports is non-conductive.
16. The method of claim 15 , wherein said positioning comprises a technique selected from the group consisting of printing, dispensing and stamping.
17. The method of claim 15 , further comprising removing the carrier from the chip package.
18. The method of claim 15 , wherein said electrical coupling comprises forming wire bonds.
19. The method of claim 15 , wherein said at least one of the one or more die supports includes a non-conductive epoxy.
