摘要:
A lead frame and a method of fabricating a semiconductor package including the lead frame, where the lead frame includes a die pad, a tie bar supporting the die pad, and a plurality of leads. The leads may include inner and outer leads arranged along an outer periphery of the die pad, with each of the inner and outer leads having tip terminals. The lead frame may include a connecting bar connected to tip terminals of each of the inner leads. In the method, a bonding pad of a semiconductor chip is mounted on the die pad and connected via a conductive wire to the inner leads of the lead frame. The semiconductor chip, wire and inner leads may be subjected to a molding process, and the connecting bar which connects the tip terminals of the inner leads may be cut so as to independently separate each of the inner leads from the die pad.

An interposer chip may include an insulating substrate, conductive patterns, and a test pattern. The conductive patterns may be formed on the insulating substrate. Further, the conductive patterns may be electrically connected to conductive wires. The test pattern may be connected to the conductive patterns. A test current for testing an electrical connection between the conductive patterns and the conductive wires may flow through the test pattern. Thus, the interposer chip may have the test pattern connected to the conductive patterns, so that the test current may flow to the test pattern through the conductive wires and the conductive patterns. As a result, an electrical connection between the conductive wires and the conductive patterns may be identified based on the test current supplied to the test pattern.

A semiconductor package may include a heat sink. The heat sink may be disposed above and spaced apart from a substrate, which may support a semiconductor chip. The heat sink may have a hole. A liquid molding compound may be provided through the hole of the heat sink to form an encapsulant. The encapsulant may seal the semiconductor chip, leaving an upper portion of the heat sink exposed. A tape supporting the heat sink may be provided on the substrate. The tape may be removed after the encapsulant is provided.

摘要:
A multi-chip package (MCP) that incorporates a leadframe pad arranged and configured to allow the active surface of a first chip to be mounted on a lower surface of the leadframe pad and a second chip to be mounted on an upper surface of the leadframe pad whereby the first and second chips may be mounted and wire bonded to inner leads without inverting the leadframe, thereby reducing the likelihood of damage during manufacturing and allowing for a reduction in package thickness. The first and second chips, as well as the bonding wires that connect the chips to inner leads of the leadframe may be sealed in a package body. Outer leads extending from the package body and integrally formed with the inner leads may be formed to provide finished packages having a variety of mounting configurations for attachment to circuit boards or other applications.
