  • Publication number: 20120028459
    Abstract: A manufacturing process of a circuit substrate is provided. A conductive structure including a first patterned conductive layer, a first dielectric layer, a second dielectric layer, a first conductive layer, and a second conductive layer is provided. The first dielectric layer and the second dielectric layer are respectively disposed on two opposite surfaces of the first patterned conductive layer. The first conductive layer and the second conductive layer are respectively disposed on the first dielectric layer and the second dielectric layer. The first dielectric layer is between the first patterned conductive layer and the first conductive layer. The second dielectric layer is between the first patterned conductive layer and the second conductive layer. A conductive via is formed at the conductive structure. The first conductive layer and the second conductive layer are patterned to respectively form a second patterned conductive layer and a third patterned conductive layer.

  • Patent number: 7330293
    Abstract: An optical scanning unit designed to provide a sufficient optical path length between a light source and an exposed object while reducing the overall space it occupies. The optical scanning unit may include a light source that produces and emits at least one beam, a beam deflector that deflects and scans the beam emitted by the light source in main scanning direction of an exposed object, and a planar optical system (POS) that is disposed in an optical path between the light source and the exposed object. The POS is designed to maintain a sufficient optical path length of an incident beam while reducing the space occupied by the optical scanning unit.
