  • Patent number: 9826646
    Abstract: A component built-in board comprises a multi-layer structure comprising a plurality of unit boards stacked therein a plurality of electronic components built in thereto in a stacking direction. The plurality of unit boards include: a first board having a first insulating layer and comprising an opening in which the electronic component is housed; and an intermediate board adjacent to the first board and comprising a first adhesive layer provided on at least a side of the first board of a second insulating layer. The intermediate board includes a first wiring layer formed at a position overlapping in the stacking direction a gap between an inner periphery of the opening and an outer periphery of the electronic component of the first board on a surface on the first board side of the second insulating layer.
    Type: Grant

  • Patent number: 7863719
    Abstract: A semiconductor device of the invention includes a semiconductor substrate having a first insulating section formed on one surface thereof. A first conductive section is disposed on the one surface of the semiconductor substrate. A second insulating section is superimposed over the first insulating section and covers the first conductive section. A second conductive section is superimposed over the second insulating section. A third insulating section is disposed over the second insulating section and covers the second conductive section. These first conductive section, second insulating section, second conductive section, third insulating section, and terminal altogether constitute a structure. A third opening is formed between adjacent structures. The third opening is formed passing through the third and second insulating sections to expose the first insulating section.
