  • Patent number: 8072732
    Abstract: A capacitor is provided having a tough surface portion which prevents cracking that tends to occur when the capacitor is built-in or surface-mounted on a wiring board. A ceramic sintered body of the capacitor includes a capacitor forming layer portion, a cover layer portion and an interlayer portion. The capacitor forming layer portion has a laminated structure wherein ceramic dielectric layers and inner electrodes connected to a peripheral portion of capacitor via conductors, are alternately laminated. The cover layer portion is exposed at a surface portion of the ceramic body and has a laminated structure wherein ceramic dielectric layers and dummy electrodes not connected to the capacitor via conductors, are alternately laminated.

  • Patent number: 8028653
    Abstract: A filament post used in plasma-enhanced chemical vapor deposition has an outer shell and an inner post. An electrical potential is applied only to the inner post to ensure that there is no impact on the plasma density and the carbon film properties. The inner post and the outer shell are electrically insulated by ceramic insulators, such that no electrical potential is applied to outer shell. The stress generated in the carbon film is directly related to the electrical potential of the surface to which the film is deposited. The carbon film deposited on the outer shell of the post is not highly stressed, which significantly reduces film delamination from the filament post surfaces.

  • Patent number: 7733662
    Abstract: A process for fabricating a circuit board with an embedded passive component is provided. First, an electrode-patterned layer having electrodes is formed on a surface of a conductive layer. Then, a passive component material is filled in the intervals between the electrodes. Then, the conductive layer and the electrode-patterned layer are laminated to a dielectric layer, wherein the electrode-patterned layer is embedded in the dielectric layer. Next, the conductive layer is patterned to form a circuit layer.

  • Patent number: 6628531
    Abstract: A multi-layer micro-printed circuit board (PCB) is disclosed, which defines a magnetic component, such as a transformer, using planar technology. Instead of using the traditional twelve-layer PCB incorporating both a primary and a secondary winding, this invention stacks multiple PCBs, each having four or six layers and each including a single winding (either the primary or the secondary). The PCBs are stacked in an offset arrangement such that the pins penetrating the PCB or PCBs including the primary winding or windings do not penetrate the PCB or PCBs including the secondary winding or windings. Additionally, this offset arrangement prevents the pins penetrating the secondary PCBs from penetrating the primary PCBs in the same manner. This offset configuration thereby avoids significant flashover problems associated with current planar components.
