  • Publication number: 20100009173
    Abstract: The present invention is directed to non-lithographic patterning by laser (or similar-type energy beam) ablation, where the ablation system ultimately results in circuitry features that are relative free from debris induced over-plating defects (debris relating to the ablation process) and fully additive plating induced over-plating defects. Compositions of the invention include a circuit board precursor having an insulating substrate and a cover layer. The insulating substrate is made from a dielectric material and also a metal oxide activatable filler. The cover layer can be sacrificial or non-sacrificial and is used to remediate unwanted debris arising from the ablation process.

  • Patent number: 6728445
    Abstract: A wavelength selective optical device for locking to a selected wavelength in an ITU grid includes a first waveguide, a second waveguide, a heating element and a control unit. The first waveguide includes a tunable filter formed in the first waveguide and the second waveguide includes a reference filter formed in the second waveguide. The heating element is in thermal contact with the tunable filter and the reference filter and the control unit is coupled to the heating element and the reference filter. The control unit varies a temperature of the heating element responsive to an indication signal provided by the reference filter to adjust the selected channel of the tunable filter.
