    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.

    Abstract: A plurality of pressure sensor dice are attached to an array of pressure sensor die attach sites located on a substrate. The pressure sensor dice are then electrically connected to the pressure sensor die attach sites using standard wire bond techniques. The resulting array of pressure sensor sub-assemblies is then molded, using a mold tool that closes on three sides of the substrate so that a cavity is formed that is open on the fourth side. A portion of the outer surface of the micro-machine element of each pressure sensor die is left exposed at the bottom of a cavity or hole in the encapsulant. After molding, the exposed outer surface of the micro-machine element is covered with a pressure coupling gel applied in the cavity. The resulting array of packaged pressure sensors are then sigulated using well know sawing or laser techniques or by snapping a specially formed snap array.

    Abstract: Semiconductor packages and other electronic assemblies having an active heat sink are disclosed, along with methods of making the same. The active heat sink includes a cavity partially filled with a heat activated liquid. Heat generated during operation of a chip boils the heat activated liquid. The vapor condenses on an inner surface of the active heat sink and transfers heat to an outer, possibly finned, surface exposed to ambient to dissipate heat. In some embodiments, the active heat sink may be a closed vessel mounted on the chip. In some embodiments, the vessel of the active heat sink is formed from a die pad of a leadframe substrate. The die pad includes a recess that forms the active heat sink cavity when bonded to the back surface of the chip. The heat activated liquid directly contacts the back surface of the chip in these embodiments.

    Abstract: A wafer is singulated from the back-side surface of the wafer using laser ablation, thus protecting the front-side surface of the wafer and, more particularly, the integrated circuits and/or functional units on the front-side surface. Since, according to the invention, no saw blade is used, the width of the scribe lines does not need to be any larger than the width of the beam from the laser plus some minimal tolerance for alignment. As a result, using the invention, the width of scribe lines is on the order of twenty-four times smaller than the width of scribe lines required by the prior art methods.
