    摘要: A package includes a substrate having an electronic component flip chip mounted thereto by flip chip bumps. The electronic component includes an active surface and an inactive surface. Electrically conductive columns (TSV) extend through the electronic component between the active surface and the inactive surface. A RDL structure is coupled to the inactive surface, the RDL structure redistributing the pattern of the electrically conductive columns at the inactive surface to a pattern of inactive surface RDL lands. The inactive surface RDL lands are exposed through via apertures of a package body. By using the inactive surface of the electronic component to distribute the inactive surface RDL lands, the allowable size of the electronic component is maximized.
