Provided are a chip on film (COF) package and semiconductor having the same. The COF package can include a flexible film having first and second surfaces opposite to and facing each other and including a conductive via penetrating from the first surface to the second surface, first and second conductive patterns respectively is on the first surface and the second surface and electrically connected to each other through the conductive via, an integrated circuit (IC) chip is on the first surface and electrically connected to the first conductive pattern, a test pad overlaps the conductive via and is electrically connected to at least one of the first conductive pattern and the second conductive pattern, and an external connection pattern is on the second surface spaced apart from the conductive via and electrically connected to the second conductive pattern.

Chip on film package including test pads and semiconductor devices including the same

A semiconductor device package includes a semiconductor chip including a conductive pad, a die pad on which the semiconductor chip is mounted and having a first thickness, a lead pattern including a first portion disposed adjacent to the edge of the die pad and having the first thickness and a second portion having a second thickness greater than the first thickness, a heat radiation member disposed on the die pad and the lead pattern and including a groove formed at its bottom surface, and a conductive line disposed to electrically connect the conductive pad to the lead pattern corresponding to the conductive pad and partially inserted into the groove.

Method of fabricating a semiconductor device package including a heat radiation plate

Disclosed are a repairable multi-chip package and a high-density memory card having the multi-chip package. The package includes a circuit substrate having bonding tips on a first surface and external contact pads on a second surface opposite to the first surface. The bonding tips and the external contact pads are electrically connected to each other. The package also includes at least two memory chips each mounted on the first surface and having chip pads thereon. The package includes electrically connecting members coupling each bonding tip to each chip pad, and an encapsulation layer covering the chips and the electrically connecting members. Particularly, the encapsulation layer is divided into two or more parts, and the bonding tips are partially embedded in and partially exposed out of the divided encapsulation layer. Accordingly, the exposed bonding tips can be selectively cut or re-connected for repairing the multi-chip package. Additionally, a high-density memory card having the package is also disclosed.

Repairable multi-chip package and high-density memory card having the package

A high-density memory card comprises a base card and two packages fixedly mounted within the base card. The two packages are attached to the base card and face each other. In one embodiment, a first package comprises a first substrate and at least one memory chip, and a second package comprises a second substrate and at least one memory chip. A first surface of the first substrate has external connection pads formed thereon and is exposed from the memory card. A second surface of the first substrate has first connection pads formed thereon. The memory chips are mounted on the second surface and electrically connected to each other. A third surface of the second substrate is exposed from the memory card, and a fourth surface of the second substrate has second connection pads formed thereon. The memory chips are mounted on the fourth surface and electrically connected to each other. The base card further includes internal connection means, and the first and the second connection pads are electrically connected to the internal connection means. The external connection pads provide electrical connection between said internal connection means to an external system. By connecting two packages to the base card, the memory card of the present invention can increase the memory density of the smart cart four times or more. Also, the problems encountered in the conventional smart card manufacturing process or the test process due to the use of plural memory chips can be prevented.

Higher-density memory card

The present invention provides a memory card having a reduced size as much as that of the package. The memory card includes electrical contact pads disposed in a single row on one end of the memory card. The memory card further comprises a card base and a semiconductor package. The card base has a first surface and a second surface, the first surface having a cavity formed thereon. The semiconductor package comprises a substrate, memory chips, and a molding resin layer, and is mounted on the cavity so that the external contact pads are exposed. Circuit wirings are formed on an inner surface of the substrate and electrically connected to the external contact pads that are formed on an outer surface of the substrate.
