Abstract
An integrated fan-out (InFO) package includes a die, an encapsulant laterally encapsulating the die, and a redistribution structure. The redistribution structure is disposed on the encapsulant. The redistribution structure includes a plurality of routing patterns and a plurality of alignment marks. The routing patterns are electrically connected to the die. The alignment marks surround the routing patterns. The alignment marks are electrically insulated from the die and the routing patterns. At least one of the alignment marks is in physical contact with the encapsulant, and the alignment marks located at different level heights are arranged in a non-overlapping manner vertically.
