Semiconductor package and method of manufacturing the semiconductor package

Abstract

A semiconductor package and a method of manufacturing the semiconductor package are disclosed. A semiconductor package in accordance with an embodiment of the present invention includes a substrate, which has a ground circuit formed thereon, a semiconductor chip, which is mounted on the substrate, a conductive first shield, which is formed on an upper surface of the semiconductor chip and connected with the ground circuit, and a conductive second shield, which covers the substrate and the semiconductor chip and is connected with the first shield. With a semiconductor package in accordance with an embodiment of the present invention, grounding is possible between semiconductor chips because a shield is also formed on an upper surface of the semiconductor chip, and the shielding property can be improved by a double shielding structure.

AI Technical Summary

Benefits of technology

[0009]The present invention also provides a semiconductor package and a method of manufacturing the semiconductor package that can be easily grounded for shielding.

Problems solved by technology

The electromagnetic waves not only disturb other semiconductor chips or lower the efficiency of signal transfer but also are harmful to the human body.

However, although the shielding technology was able to block the electromagnetic waves emitted to the outside of the semiconductor package or the electromagnetic waves permeated into the semiconductor package from the outside, it has not been able to block the electromagnetic waves between the semiconductor chips within the semiconductor package.

Moreover, the shielding member and a ground circuit need to be connected to each other, but it has been difficult to provide a connection space between the shielding member and the ground circuit as the semiconductor package becomes smaller and thinner.
