SEMICONDUCTOR PACKAGE WITH REDISTRIBUTION STRUCTURE AND MANUFACTURING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18155672 titled 'SEMICONDUCTOR PACKAGE WITH REDISTRIBUTION STRUCTURE AND MANUFACTURING METHOD THEREOF

Simplified Explanation

The abstract describes a semiconductor package that includes a semiconductor die, a redistribution structure, and connective terminals. The redistribution structure is located on the semiconductor die and consists of a first metallization tier sandwiched between two dielectric layers. The first metallization tier includes conductive traces for routing electrical connections to the semiconductor die and a shielding plate that is electrically isolated from the semiconductor die. The connective terminals consist of dummy connective terminals and active connective terminals. The dummy connective terminals are placed on the redistribution structure and are electrically connected to the shielding plate, while the active connective terminals are also located on the redistribution structure and are electrically connected to the routing conductive traces. The vertical projections of the dummy connective terminals fall on the shielding plate.

• The semiconductor package includes a redistribution structure with a first metallization tier and dielectric layers.
• The first metallization tier contains conductive traces for routing electrical connections and a shielding plate.
• Connective terminals are present, including dummy connective terminals and active connective terminals.
• The dummy connective terminals are connected to the shielding plate, while the active connective terminals are connected to the routing conductive traces.

• The technology allows for more efficient use of space within the semiconductor package, enabling smaller and more compact electronic devices.

Original Abstract Submitted

A semiconductor package includes a semiconductor die, a redistribution structure and connective terminals. The redistribution structure is disposed on the semiconductor die and includes a first metallization tier disposed in between a pair of dielectric layers. The first metallization tier includes routing conductive traces electrically connected to the semiconductor die and a shielding plate electrically insulated from the semiconductor die. The connective terminals include dummy connective terminals and active connective terminals. The dummy connective terminals are disposed on the redistribution structure and are electrically connected to the shielding plate. The active connective terminals are disposed on the redistribution structure and are electrically connected to the routing conductive traces. Vertical projections of the dummy connective terminals fall on the shielding plate.
