Integrated circuit packaging

Cross section of a dual in-line package. This type of package houses a small semiconducting die, with microscopic wires attaching the die to the lead frames, allowing for electrical connections to be made to a PCB.

Integrated circuit packaging is the final stage of semiconductor device fabrication, in which the die is encapsulated in a supporting case that prevents physical damage and corrosion. The case, known as a "package", supports the electrical contacts which connect the device to a circuit board.

The packaging stage is followed by testing of the integrated circuit.
