    Abstract: A semiconductor printed circuit board assembly (PCBA) and method for making same for use in electronic packages having a core layer of copper-invar-copper (CIC) with a layer of dielectric substrate placed on the core layer. A second layer of dielectric substrate is placed on the lower surface of the core layer of CIC. The layers are laminated together. Blind vias are laser drilled into the layers of dielectric substrate. The partially completed PCBA is subjected to a reactive ion etch (RIE) plasma as a first step to clean blind vias in the PCBA. After the plasma etch, an acidic etchant liquid solution is used on the blind vias. Pre-plating cleaning of blind vias removes a majority of oxides from the blind vias. Seed copper layers are then applied to the PCBA, followed by a layer of copper plating that can be etched to meet the requirements of the PCBA.

    Abstract: An improved metal interconnect is formed with reduced metal voids and dendrites. An embodiment includes forming a mask layer on a dielectric layer, forming openings in the mask and dielectric layers, depositing a planarization layer over the mask layer and filling the openings, planarizing to remove the mask layer, removing the planarization layer from the openings, and filling the openings with metal. The planarization step prior to depositing the metal removes the etch undercut that occurs during formation of the openings and reduces the aspect ratio in the openings, thereby improving metal fill uniformity.

    Abstract: In connection with a semiconductor device in which a conductive member is coupled to the surface of a bonding pad exposed from an opening formed in a passivation film, there is provided a technique able to suppress the occurrence of a crack in the passivation film. A second planar distance between a first end of an electrode layer and a first end of a pad is greater than a first planar distance between the first end of the electrode layer and a first end of an opening. Since the second planar distance between the first end of the electrode layer and the first end of the pad is long, even when a coupled position of wire is deviated to the first end side of the electrode layer, stress caused by coupling of the wire to a stepped portion of the electrode layer can be prevented from being transmitted to the first end portion of the pad.

    Abstract: The RTD device of the present invention is comprised of a semiconductor substrate and a substantially thin conductive metal layer disposed upon the semiconductor substrate, wherein the conductive metal has a substantially linear temperature-resistance relationship. The conductive layer is etched into a convoluted RTD pattern, which consequently increases the overall resistance and minimizes the overall mass of the RTD assembly. A contact glass cover and a conductive metal-glass frit are placed over the RTD assembly to hermetically seal the RTD. The resultant structure can be “upside-down” mounted onto a header or a flat shim so that the bottom surface of the semiconductor substrate is exposed to the external environment, thus shielding the RTD from external forces. The resultant structure is a low mass, highly conductive, leadless, and hermetically sealed RTD that accurately measures the temperature of liquids and gases and maintains fast response time in high temperatures and harsh environments.

  • Patent number: 7884032
    Abstract: A system, method and apparatus is capable of producing layers of various materials stacked on one another on a substrate without exposing the substrate to the pressure and contaminants of ambient air until the stack is complete. In one aspect, the stack of layers can include both an insulative layer of one or more insulative films, and a conductive metal layer of one or more conductive metal layer films. In another aspect, a bias signal of positive and negative voltage pulses may be applied to a target of a deposition chamber to facilitate deposition of the target material in a suitable fashion. In yet another aspect, one or more of the deposition chambers may have associated therewith a pump which combines a turbomolecular pump and a cryogenic pump to generate an ultra high vacuum in that chamber. Other features are described and claimed.

  • Patent number: 7842596
    Abstract: A thin silicon solar cell having a back dielectric passivation and rear contact with local back surface field is described. Specifically, the solar cell may be fabricated from a crystalline silicon wafer having a thickness from 50 to 500 micrometers. A barrier layer and a dielectric layer are applied at least to the back surface of the silicon wafer to protect the silicon wafer from deformation when the rear contact is formed. At least one opening is made to the dielectric layer. An aluminum contact that provides a back surface field is formed in the opening and on the dielectric layer. The aluminum contact may be applied by screen printing an aluminum paste having from one to 12 atomic percent silicon and then applying a heat treatment at 750 degrees Celsius.

  • Publication number: 20100255667
    Abstract: It was found out that when radicals generated by plasma are fed to a treatment chamber via a plurality of holes (111) formed on a partition plate which separates a plasma-forming chamber (108) from the treatment chamber, and the radicals are mixed with a treatment gas which is separately fed to the treatment chamber, the excitation energy of the radicals is suppressed and thereby the substrate surface treatment at high Si-selectivity becomes possible, which makes it possible to conduct the surface treatment of removing native oxide film and organic matter without deteriorating the flatness of the substrate surface. The radicals in the plasma are fed to the treatment chamber via radical-passing holes (111) of a plasma-confinement electrode plate (110) for plasma separation, the treatment gas is fed to the treatment chamber (121) to be mixed with the radicals in the treatment chamber, and then the substrate surface is cleaned by the mixed atmosphere of the radicals and the treatment gas.
