A flip chip packaging process uses an underfill as an encapsultant to reduce the possibility of delamination from occurring due to differential coefficients of thermal expansion, and thus the reliability of a flip chip package structure can be increased. Furthermore, the flooding of the encapsulant over the cutting line need not be taken into consideration for cutting the substrate. Therefore, the usage area of the substrate usage is increased, i.e., more chips can be mounted per unit area of the substrate.

Flip chip packaging process

A flip chip package structure and manufacturing method thereof is provided. A chip is electrically connected to a substrate. A heat sink is attached to the backside of the chip. The heat sink has at least a through hole located at a peripheral region and laterally adjacent to the chip. A dispensing process is carried out to deliver an underfill material via the through hole such that the space between the chip and the substrate is filled. The underfill material also extends to cover a portion of the heat sink so that the heat sink and the substrate are connected together. The underfill material is cured to fix the heat sink, the substrate and the chip in position.

Flip chip package and manufacturing method thereof

A semiconductor package structure includes a semiconductor component, a substrate, solder bumps, underfill, a buffer means, and solder balls. The substrate is under the semiconductor component. A joint area is formed between the first surface of the semiconductor and the upper surface of the substrate. Several solder bumps are disposed in the joint area, for electrically connecting the semiconductor component and the substrate. The underfill is filled in the joint area, for coating the solder bumps and tightly jointing the semiconductor component and the substrate. The buffer means is situated in the jointing area, for buffering the underfill to be confined in the joint area. Several solder balls are disposed on the lower surface of the substrate.

Semiconductor package structure

A flip chip package structure comprising a chip, a substrate, at least a first bump and a plurality of second bumps is provided. The chip has a first bump-positioning region and the substrate has a second bump-positioning region. The substrate has at least a first hole and multiple second holes. The first hole and the second holes are located within the second bump-positioning region. The first hole has a depth greater than that of the second hole. The first bump is set up between the first bump-positioning region of the chip and the second bump-positioning region of the substrate. The first bump is bonded to the substrate through the first holes. The second bumps are set up between the first bump-positioning region of the chip and the second bump-positioning region of the substrate. The second bumps are bonded to the substrate through the second holes. The first bump has a volume greater than the volume of the second bump.

Flip chip package structure

A chip package structure includes a substrate having an upper surface and a lower surface, a chip having an active surface and a back surface, a stiffener, a first heat sink and a second heat sink. The active surface of the chip is attached on the upper surface of the substrate via bumps, so that the chip electrically connects to the substrate. The stiffener is disposed on the upper surface of the substrate and around the chip. The first heat sink is disposed on the back surface of the chip and on the stiffener ring. The second heat sink is disposed on the lower surface of the substrate.

Chip package structure with dual heat sinks

A manufacturing method of a flip chip package mainly comprises the following steps. Initially, a chip having an active surface with a plurality of bumps formed thereon is provided. Next, the active surface of the chip is faced to and disposed on an upper surface of a substrate. In such manner, the chip will be electrically connected to the substrate and a gap between the chip and the substrate will be formed. Afterwards, an underfill is filled in the gap and then a first curing process is performed to have the underfill partially hardened to have the underfill transformed into a partially hardened underfill. Finally, the combination of the chip, the substrate and the partially hardened underfill is flipped over to have the substrate located above the chip, then a second curing process is performed to have the partially hardened underfill into a fully hardened underfill, and then flipping over the combination of the chip, the substrate and the fully hardened underfill.

Manufacturing method of flip chip package

A face-to-face multi-chip flip-chip package includes a first chip, at least a second chip and a package substrate. The package substrate has a top surface, a bottom surface and a concave wall between the top surface and the bottom surface. The second chip is flip-chip mounted on active surface of the first chip. The first chip is mounted on the package substrate so that the second chip is placed inside a chip accommodation space of the package substrate which is defined by the concave wall. A side surface of the second chip is a progressive distance from the chip accommodation space for lessening capillary flow of underfilling material between the concave wall of the package substrate and the side surface of the second chip during dispensing the underfilling material.

Face-to-face multi-chip flip-chip package

A method for controlling the adhesive distribution in a flip-chip semiconductor product has steps: (a) providing a substrate with a flip-chip electrically mounted on the substrate via multiple bumps, (b) providing an dam along an edge of the flip-chip, and (c) depositing adhesive on the dam to flow into a space between the substrate and a bottom of the flip-chip by capillary effect. The shape of the dam is determined by the density of the multiple bumps to control the flowing speed of the adhesive to obtain a good adhesive distribution.
