Abstract:
A semiconductor device has a semiconductor die mounted over a surface of a substrate. A mold underfill dispensing needle has a width substantially equal to a width of the semiconductor die. The dispensing needle is placed in fluid communication with a side of the semiconductor die. A mold underfill is deposited from an outlet of the dispensing needle evenly across a width of the semiconductor die into an area between the semiconductor die and substrate without motion of the dispensing needle. The dispensing needle has a shank and the outlet in a T-configuration. The dispensing needle can have a plurality of pole portions between a shank and the outlet. The dispensing needle has a plate between a shank and the outlet. The outlet has an upper edge with a length substantially equal to or greater than a length of a lower edge of the outlet.
Abstract:
Provided is a semiconductor package including a lower package, an interposer on the lower package, and an upper package on the interposer. The lower package may include a lower package substrate, a lower semiconductor chip on the lower package substrate, and a lower heat-transfer layer on the lower semiconductor chip. The interposer may include an interposer substrate, first and second heat-transfer openings defined by recessed bottom and top surfaces, respectively, of the interposer substrate, an upper interposer heat-transfer pad disposed in the second heat-transfer opening, and an upper heat-transfer layer disposed on the upper interposer heat-transfer pad. The upper package may include an upper package substrate, an upper package heat-transfer pad, which may be disposed in a third heat-transfer opening defined by a recessed bottom surface of the upper package substrate, and an upper semiconductor chip disposed on the upper package substrate.

Abstract:
Provided are a semiconductor package and a method of fabricating the same. The package substrate includes a hole, which may be used to form a mold layer without any void. The mold layer may be partially removed to expose a lower conductive pattern. Accordingly, it is possible to improve routability of solder balls.
