Abstract: The present disclosure relates to a method for efficiently enriching lutein in broccoli sprouts under ?-aminobutyric acid combined with sodium chloride stress. In the present disclosure, Qingfeng broccoli seeds with plump particles, uniform size and germination ability are selected as raw materials; after removing impurities and being disinfected by a NaClO solution, the seeds are sprayed with distilled water for one day, then sprayed with a mixed aqueous solution of NaCl and ?-aminobutyric acid, to obtain broccoli sprouts.

Abstract: The method comprises forming a plurality of wiring pattern layers on the front surface of a substrate. In the process of forming the wiring pattern layers, an insulator protection film keeps covering over the wiring pattern on the back surface of the substrate. When the formation of the wiring pattern layers has been completed on the front surface of the substrate, a penetrating hole is bored in the cured or hardened insulator protection film. The penetrating hole may be utilized as a conductive via or a conductive through hole. A wiring pattern layer is then formed over the hardened insulator protection film on the back surface of the substrate. It is possible to omit an additional process for removing the insulator protection film. The method contributes to further facilitation of production process and further reduction in production cost.

Abstract: A dummy pad is formed through a polyimide insulating layer so as to be provided opposite to a via connecting pad formed on the surface of a ceramic substrate. A defect occurring in the via connecting pad is filled with a protrusion when the dummy pad is formed. Accordingly, the influence of the defect upon a layer above the dummy pad is prevented. Further, in a method for manufacturing a thin film wiring board obtained by forming a thin film layer on a base substrate having a via that allows interlayer electric conduction, a void defect existing in the via is filled with a conductive material having corrosion resistance against an etchant, and then the thin film layer is formed on the base substrate.
