Semiconductor package including a laser mark area comprising portions of a redistribution level layer

Abstract

A semiconductor package includes an encapsulation layer encapsulating at least one semiconductor chip, and a redistribution level layer disposed on the encapsulation layer. The redistribution level layer includes a redistribution layer and a redistribution insulating layer insulating the redistribution layer, a laser mark area is disposed on the redistribution layer and the redistribution insulating layer, and the redistribution insulating layer of the laser mark area comprises a plurality of mesh-type redistribution insulating patterns arranged apart from each other on a plane and surrounded by the redistribution layer. The redistribution level layer includes a laser mark insulating layer located on the redistribution layer and the redistribution insulating layer, wherein the laser mark insulating layer includes a laser mark exposing the redistribution layer and the mesh-type redistribution insulating patterns in the laser mark area.
