Abstract: A system in a package (SIP) includes carrier layer regions that have a dielectric material with a metal post therethrough, where adjacent carrier layer regions define a gap. A driver IC die is positioned in the gap having nodes connected to bond pads exposed by openings in a top side of a first passivation layer, with the bond pads facing up. A dielectric layer is on the first passivation layer and carrier layer region that includes filled through vias coupled to the bond pads and to the metal post. A light blocking layer is on sidewalls and a bottom of the substrate. A first device includes a light emitter that has first bondable features. The light blocking layer can block at least 90% of incident light. The first bondable features are flipchip mounted to a first portion of the bond pads.

Abstract: An electronic device includes a multilevel package substrate, conductive leads, a die, and a package structure. The multilevel package substrate has a first level, a second level, and a third level, each having patterned conductive features and molded dielectric features. The first level includes a first patterned conductive feature with multiple turns that form a first winding. The second level includes a second patterned conductive feature, and the third level includes a third patterned conductive feature with multiple turns that form a second winding. A first terminal of the die is coupled to the first end of the first winding, a second terminal of the die is coupled to the second end of the first winding, and a third terminal of the die is coupled to a first conductive lead. The package structure encloses the first die, the second die, and a portion of the multilevel package substrate.

Abstract: One example includes a method for fabricating a substrate-integrated waveguide (SIW). The method includes forming a first metal layer on a carrier surface. The first metal layer can extend along an axis. The method also includes forming a first metal sidewall extending from a first edge of the first metal layer along the axis and forming a second metal sidewall extending from a second edge of the first metal layer opposite the first edge along the axis to form a trough extending along the axis. The method also includes providing a dielectric material over the first metal layer and over the first and second metal sidewalls. The method further includes forming a second metal layer over the dielectric material and over the first and second metal sidewalls. The second metal layer can extend along the axis to enclose the SIW in all radial directions along the axis.
