Abstract

The present invention relates to a semiconductor element having conductive vias and a semiconductor package having a semiconductor element with conductive vias and a method for making the same. The semiconductor element having conductive vias includes a silicon substrate and at least one conductive via. The thickness of the silicon substrate is substantially in a range from 75 to 150 μm. The conductive via includes a first insulation layer and a conductive metal, and the thickness of the first insulation layer is substantially in a range from 5 to 19 μm. Using the semiconductor element and the semiconductor package of the present invention, the electrical connection between the conductive via and the other element can be ensured, and the electrical connection between the silicon substrate and the other semiconductor element can be ensured, so as to raise the yield rate of a product. Moreover, by employing the method of the present invention, warpage and shift of the silicon substrate can be avoided during the reflow process, so as to conduct the reflow process only a single time in the method of the present invention, thereby simplifying the subsequent process and reducing cost.
