    Abstract: A packaging semiconductor device, such as a fan-out Wafer-Level Packaging (FOWLP) device, is fabricated by providing a semiconductor device (20) having conductive patterns (22) disposed on a first surface and then forming, on the conductive patterns, photoresist islands (24) having a first predetermined shape defined by a first critical width dimension and a minimum height dimension so that a subsequently-formed dielectric polymer layer (26) surrounds but does not cover each photoresist island (24), thereby allowing each photoresist island to be selectively removed from the one or more conductive patterns to form one or more via openings (28) in the dielectric polymer layer such that each via opening has a second predetermined shape which matches at least part of the first predetermined shape of the photoresist islands.

    Abstract: A method of forming a semiconductor device is provided. The method includes forming a redistribution layer (RDL) substrate over an active side of a semiconductor die. The RDL substrate includes a plurality of under-bump metallization (UBM) structures. A die pad of a leadframe is affixed on a backside of the semiconductor die. The leadframe includes a plurality of leads having a first portion of each lead connected to the die pad and a second portion of each lead extending vertically along sidewalls of the semiconductor die toward a plane of the RDL substrate. An encapsulant encapsulates the semiconductor die and the leadframe, a lead tip portion of each lead is exposed through the encapsulant.

    Abstract: A method for manufacturing a packaged integrated circuit device includes providing a semiconductor wafer having a plurality of integrated circuit devices. Each integrated circuit device extends into the semiconductor wafer to a first depth. Prior to singulation of the integrated circuit devices on the semiconductor wafer, the method further includes forming a cut between the integrated circuit devices. The cut extends to at least the first depth, but does not extend completely through the semiconductor wafer. The cut exposes a plurality of edges of each of the integrated circuit devices. The method further includes depositing, on each integrated circuit device, a passivation layer on a top surface and on the edges.
