摘要:
A semiconductor chip package includes a main board; a ceramic substrate having a cavity within which at least one chip is electrically mounted, the cavity being placed at a lower portion of the ceramic substrate facing the main board; and a conductive shielding layer provided with a predetermined thickness on the outside of the ceramic substrate. The ceramic substrate includes: at least one first ground line electrically connecting the conductive shielding layer with the main board; at least one second ground line electrically connecting the conductive shielding layer with the chip; and at least one signal line electrically connecting the chip with the main board. Thus, manufacturing costs are lowered because of the reduced number of components being used, miniaturization in device design can be achieved because of the small volume of the package, and the ground performance can be improved.
摘要:
In a semiconductor chip, a body has a top surface where a pattern is formed, an underside surface opposing the top surface and a plurality of side surfaces. A plurality of electrode pads are formed on the top surface of the body to connect to an external terminal. A shielding conductive film is formed on the surfaces excluding the top surface of the body where the pattern is formed. A conductive via is extended through the body to connect one of the electrode pads with the conductive film.

A semiconductor multichip package includes a substrate having a top surface on which a bonding pad is formed, and a bottom surface opposing the top surface, on which an external connection terminal electrically connected with the bonding pad is formed, a first semiconductor chip mounted on a region of the top surface of the substrate excluding the bonding pad, a ceramic spacer disposed on a top surface of the first semiconductor chip and including a passive device therein, and at least one second semiconductor chip disposed on a top surface of the ceramic spacer. The ceramic spacer includes an interlayer circuit for an electrical connection between the first and second semiconductor chips, and the passive device is electrically connected to at least one of the first and second semiconductor chips. Accordingly, a package with a more compact structure can be realized.

Provided is an electron chip module having a heat sink that can increase heat dissipation efficiency. A bottom surface of a module circuit board and an upper surface of a heat sink are in direct contact with each other by using a metal wire, such that heat generated during the operation of a heat-generating device chip mounted onto the module circuit board can be effectively dissipated to the outside.
