摘要:
An elongated strip of a sheetlike substrate bearing microelectronic elements such as semiconductor chips is advanced in a downstream direction through one or more folding stations where successive portions of the substrate are folded so as to form a strip including a plurality of fold packages, each including confronting top and bottom runs and a fold region with one or more of the runs bearing one or more microelectronic elements. The strip incorporating the plural fold packages can be wound on a reel or otherwise handled, stored and shipped to a subsequent manufacturing operation, where individual fold packages can be severed from the strip.

A method of making the lidded chip assembly are provided which includes the steps of: (a) aligning a lid member with a chip member including one or more chips so that electrically conductive elements projecting from a front surface of the chip-member extend into through-holes in the lid member and at least partially control location of the lid member relative to the chip member in one or more horizontal directions parallel to the front surface; and (b) forming interconnections extending through the lid member so that the interconnections include the conductive elements. A capped chip is provided in which the conductive interconnects extend from the chip through openings in a cap member, the openings being tapered to become smaller in a direction from the bottom or inner surface of the opening towards the top or outer surface.

A thermal management apparatus includes an electrohydrodynamic fluid accelerator in which an emitter electrode and another electrode are energizable to motivate fluid flow. One of the electrodes includes a solid solution formed of a solvent metal having a first performance characteristic and a solute material having a second performance characteristic. The first and second performance characteristics are exhibited substantially independently in the electrode as the solvent metal and solute material remain substantially pure within the solid solution. A method of making an EHD product includes providing an electrode with such a solid solution and positioning the electrode relative to another electrode to motivate fluid flow when energized.
