    摘要: A method for manufacturing a wiring substrate includes forming first conductor pads and second conductor pads having a shorter inter-pad distance than the first conductor pads, forming a second insulating layer covering the first conductor pads and the second conductor pads, forming first via holes exposing the first conductor pads, applying a first desmear treatment such that residues are removed from the first via holes, forming second via holes in the second insulating layer after the first desmear treatment such that the second via holes expose the second conductor pads, applying a second desmear treatment such that residues are removed from the second via holes, forming first via conductors in the first via holes such that the first via conductors are formed on the first conductor pads, and forming second via conductors in the second via holes such that the second via conductor are formed on the second conductor pads.

    摘要: A wiring substrate includes a first wiring part including a first insulating layer and a first conductor layer laminated on the first insulating layer, and a second wiring part including a second insulating layer and a second conductor layer laminated on the second insulating layer. The thickness of the second insulating layer is smaller than that of the first insulating layer. The thickness of the second conductor layer is smaller than that of the first conductor layer. The first conductor layer includes first wirings including differential wirings having the minimum wiring width of larger than 5 μm and minimum inter-wiring distance of larger than 7 μm. The second conductor layer includes second wirings having the maximum wiring width of 5 μm or less and the maximum inter-wiring distance of 7 μm or less. The second part is positioned closer to the outermost surface of the substrate than the first part.

    摘要: A wiring substrate includes first conductor pads formed on a surface of an insulating layer, second conductor pads formed on the surface of the insulating layer, a second insulating layer covering the surface of the insulating layer and first and second conductor pads, first via conductors formed in first via holes penetrating through the second insulating layer such that the first via conductors are formed on the first conductor pads, and second via conductors formed in second via holes penetrating through the second insulating layer such that the second via conductors are formed on the second conductor pads. The first and second conductor pads are formed such that an annular width amount of each second conductor pad is smaller than an annular width amount of each first conductor pad and that a haloing amount in each second conductor pad is smaller than a haloing amount in each first conductor pad.

    摘要: A wiring substrate includes an insulating layer including resin and filler particles, conductor layers including an upper-layer conductor layer and a lower-layer conductor layer such that the insulating layer is sandwiched between the upper-layer and lower-layer conductor layers, and a penetrating conductor formed in the insulating layer such that the penetrating conductor is penetrating through the insulating layer and connecting the upper-layer and lower-layer conductor layers. The penetrating conductor is formed such that the penetrating conductor has a first length which is the maximum width of the penetrating conductor in the direction orthogonal to the thickness direction of the wiring substrate and the first length is 25 μm or less, and the insulating layer is formed such that the maximum particle size of the filler particles in a region within the distance of 40% of the first length from the penetrating conductor is 20% or less of the first length.
