Anti-fuse on and/or in package

摘要

A package structure includes an integrated circuit die, a redistribution structure, an anti-fuse, and external connectors. The integrated circuit die is embedded in an encapsulant. The redistribution structure is on the encapsulant and is electrically coupled to the integrated circuit die. The anti-fuse is external to the integrated circuit die and the redistribution structure. The anti-fuse is mechanically and electrically coupled to the redistribution structure. The external connectors are on the redistribution structure, and the redistribution structure is disposed between the external connectors and the encapsulant.

1. A package structure comprising:
an integrated circuit die embedded in an encapsulant; a first redistribution structure on a first side of the encapsulant and electrically coupled to the integrated circuit die; a first anti-fuse external to the integrated circuit die and the first redistribution structure, the first anti-fuse being mechanically and electrically coupled to the first redistribution structure; first external connectors on the first redistribution structure, the first redistribution structure being disposed between the first external connectors and the encapsulant, the first external connectors and the first anti-fuse being disposed on a same side of the first redistribution structure; a second redistribution structure on a second side of the encapsulant and electrically coupled to the integrated circuit die, the second side of the encapsulant being opposite of the first side of the encapsulant; a second anti-fuse external to the integrated circuit die and the second redistribution structure, the second anti-fuse being directly mechanically and electrically coupled to the second redistribution structure, the second anti-fuse being interposed between the first redistribution structure and the second redistribution structure; and second external connectors on the second redistribution structure, the second redistribution structure being disposed between the second external connectors and the encapsulant, the second external connectors and the second anti-fuse being disposed on opposite sides of the second redistribution structure.
