    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 manufacturing a semiconductor device is provided. The method includes forming a first non-conductive layer over a top side a semiconductor die and patterning the first non-conductive layer to form a collar structure surrounding an opening exposing a top surface of a bond pad. A second non-conductive layer is formed over the first non-conductive layer and exposed portions of the top side of the semiconductor die. The second non-conductive layer is different from the first non-conductive layer. The second non-conductive layer is patterned to expose the top surface of the bond pad and inner sidewalls of the of the collar structure surrounding the opening such that the second non-conductive layer does not contact the bond pad. A metal redistribution layer is formed over the second non-conductive layer and exposed top surface of the bond pad.

    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.
