A packaged microelectronic element includes a microelectronic element having a front surface and a plurality of first solid metal posts extending away from the front surface. A substrate has a major surface and a plurality of conductive elements exposed at the major surface and joined to the first solid metal posts. In particular examples, the conductive elements can be bond pads or can be second posts having top surfaces and edge surfaces extending at substantial angles away therefrom. Each first solid metal post includes a base region adjacent the microelectronic element and a tip region remote from the microelectronic element, the base region and tip region having respective concave circumferential surfaces.

Methods of backside planarization processes have been developed to gain a high resolution backside process lithography and to make possible the development of dual faced MMICs and circuits. Two different processes have been employed to planarize via structures of various depths, one including epoxy-fill via structures with depths of 10 mils and the other solid-metal via structures with depths of 3.5 mils. Application of a wafer fabricated using methods of the present invention has been demonstrated in a monolithic circuit, where bias control to the frontside of the wafer was established by solder bumps on the planarized backside surface of a wafer including epoxy-filled via structures.

It is an object of the present invention to provide an improved orthopedic implant system with satisfied biological, mechanical and morphological compatibilities. Solid metal femoral stem (entirely or partially) and solid metal acetabular head (entirely or partially) are covered with diffusion-bonded foamed-shaped sheet made of commercially pure titanium or titanium alloy(s). The open-cells in said foamed metal sheet are impregnated with biocompatible polymethyl methacrylate resin cement, which is reinforced with selected oxides (e.g., alumina, magnesia, zirconia, or a combination of these oxides) along with an application of a small amount of a metal primer agent.

Carpeted floor covering articles comprising carpet pile fibers to which a topical antimicrobial application of solid particles has been applied either during or after product manufacture (such as part of a cleaning or treatment process) are provided. Such a topical treatment includes specific inorganic antimicrobial metal ion-based solid compounds, such as silver ion-exchange compounds, silver zeolites, and/or silver glasses, which may or may not be dispersed within a liquid medium for ease in handling and application. Such treatments also optionally include compositions of stain resistant agents, anti soil-redeposition compounds and liquids, surfactants, antistatic agents, and the like, to impart other characteristics to the target carpeted products. Such carpeted products thus exhibit excellent antimicrobial characteristics at both the surface of the carpet pile, as well as within the pile itself. Furthermore, it has been found that application of such solid metal-ion based antimicrobials permits the ability to increase antimicrobial activity for the target carpet product after vacuuming.

A vent assembly, suitable for marine use including, for example, venting an enclosure, such as an engine compartment, on a boat. The vent assembly has substantially the external appearance of a cast or machined, one piece, stainless steel vent, at a cost very little more than a molded plastics vent. A molded plastics vent has a head perforated by a pattern of ventilating slots separated by flanking strips. A decorative, corrosion-resistant, sheet metal cover shell lies tight against the front side of the molded plastics vent and has a pattern of slots and strips mapping substantially on the pattern of slots and strips of the molded plastics vent. Snap-fit fasteners fix the cover shell on the vent so that the cover shell slots are a substantially flush continuation of the vent slots, so as to provide the decorative appearance of a solid metal vent at substantially lower cost and without compromising or through flow capability.

Disclosed herein are a variety of microfluidic devices and solid, typically electrically conductive devices that can be formed using such devices as molds. In certain embodiments, the devices that are formed comprise conductive pathways formed by solidifying a liquid metal present in one or more microfluidic channels (such devices hereinafter referred to as “microsolidic” devices). In certain such devices, in which electrical connections can be formed and/or reformed between regions in a microfluidic structure; in some cases, the devices/circuits formed may be flexible and/or involve flexible electrical components. In certain embodiments, the solid metal wires/conductive pathways formed in microfluidic channel(s) may remain contained within the microfluidic structure. In certain such embodiments, the conductive pathways formed may be located in proximity to other microfluidic channel(s) of the structure that carry flowing fluid, such that the conductive pathway can create energy (e.g. electromagnetic and/or thermal energy) that interacts withy and/or affects the flowing fluid and/or a component contained therein or carried thereby. In other embodiments, a microsolidic structure may be removed from a microfluidic mold to form a stand-alone structure. In certain embodiments, the solid metal structures formed may interact with light energy incident upon a structure or may be used to fabricate a light-weight electrode. Another aspect of the invention relates to the formation of self-assembled structures that may comprise these electrically conductive pathways/connections.
