Patent ID: 10163807

Abstract:
A method includes forming an alignment pattern over an insulating layer formed over a carrier. A die is mounted over the carrier and encapsulated. Connectors are formed and the structure is attached to a debond tape. The carrier is removed. A cutting device is aligned to a backside of the insulating layer using the alignment pattern. The first insulating layer and encapsulant are cut from the backside of the insulating layer. Another method includes scanning a backside of a packages structure for an alignment pattern in a first package area of the packages structure. A cutting device is aligned to a cut-line in a non-package area of the packages structure based on the alignment pattern and packages are singulated. An InFO package includes an insulating layer on the backside, the insulating layer having a laser marking thereon. The InFO package also includes an alignment pattern proximate to the insulating layer.
