Abstract
A mounting for a package containing a semiconductor chip is disclosed, along with methods of making such a mounting. The mounting includes a substrate having a mounting surface with conductive traces thereon, and an aperture extending through the substrate. The package includes a base, such as a leadframe or a laminate sheet, and input/output terminals. A chip is on a first side of the base and is electrically connected (directly or indirectly) to the input/output terminals. A cap, which may be a molded encapsulant, is provided on the first side of the base over the chip. The package is mounted on the substrate so that the cap is in the aperture, and a peripheral portion of the first side of the base is over the mounting surface so as to support the package in the aperture and allow the input/output terminals of the package to be juxtaposed with to the circuit patterns of the mounting surface. Because the cap is within the aperture, a height of the package above the mounting surface is minimized.
