Abstract: A circuit board includes a substrate, a build-up circuit structure, a graphene oxide layer, a graphene layer, and an insulating material layer. The build-up circuit structure is disposed on the substrate, including at least one inner circuit, at least one dielectric layer, an outer circuit, and multiple conductive vias. The dielectric layer is disposed on the inner circuit. The outer circuit is disposed on the dielectric layer. The conductive vias penetrate the dielectric layer and electrically connect the inner circuit and the outer circuit. The graphene oxide layer and the graphene layer are disposed on the build-up circuit structure at an interval. The graphene oxide layer and the graphene layer are respectively disposed in correspondence to the dielectric layer and the outer circuit. The insulating material layer is disposed on the graphene oxide layer and the graphene layer. The insulating material layer has an opening, which exposes the graphene layer.

Abstract: A chemical mechanical planarization (CMP) system including a capacitive deionization module (CDM) for removing ions from a solution and a method for using the same are disclosed. In an embodiment, an apparatus includes a planarization unit for planarizing a wafer; a cleaning unit for cleaning the wafer; a wafer transportation unit for transporting the wafer between the planarization unit and the cleaning unit; and a capacitive deionization module for removing ions from a solution used in at least one of the planarization unit or the cleaning unit.

Abstract: An apparatus includes a laminate, the laminate including a dielectric layer having a first surface and a second surface opposed to the first surface, and a conductive layer forming a circuit element overlying the first surface of the dielectric layer. The apparatus further includes a magnetic layer over the conductive layer. A first edge surface of the magnetic layer is coplanar with a first edge surface of the laminate, and a second edge surface of the magnetic layer is coplanar with a second edge surface of the laminate.

Abstract: A vehicular light includes a body having a base. A cover is mounted to a surface of the base and made of transparent material. A circuit board is mounted in the base. A light emitting element is mounted to the circuit board. An intermediate member is mounted between the cover and the circuit board. The intermediate member includes a light transmittable section covering the light emitting element. A frame is mounted between the light transmittable section and the light emitting element and has a substantially bowl-shaped inner side. The frame and the intermediate member are separable from each other and detachable from the cover and the circuit board. The frame includes a frame wall. A through-hole is formed in a bottom of the frame. The light emitting element extends through the through-hole and received in the frame and faces the light transmittable section.
