    Abstract: A substrate for packaging a semiconductor device includes a first dielectric layer having a first surface and a second surface opposite to the first surface, a first patterned conductive layer adjacent to the first surface of the first dielectric layer, and a second patterned conductive layer adjacent to the second surface of the first dielectric layer and electrically connected to the first patterned conductive layer. The first patterned conductive layer includes a first portion and a second portion. Each of the first portion and the second portion is embedded in the first dielectric layer and protrudes relative to the first surface of the first dielectric layer toward a direction away from the second surface of the first dielectric layer. A thickness of the first portion of the first patterned conductive layer is greater than a thickness of the second portion of the first patterned conductive layer.

    Abstract: An interposer substrate includes a first circuit pattern embedded at a first surface of a dielectric layer and a second circuit pattern embedded at a second surface of the dielectric layer; a middle patterned conductive layer in the dielectric layer between the first circuit pattern and the second circuit pattern; first conductive vias, where each first conductive via includes a first end adjacent to the first circuit pattern and a second end adjacent to the middle patterned conductive layer, wherein a width of the first end is greater than a width of the second end; second conductive vias, where each second conductive via including a third end adjacent to the second circuit pattern and a fourth end adjacent to the middle patterned conductive layer, wherein a width of the third end is greater than a width of the fourth end.
