    One or more silicon-integrated-circuit chips are attached, active side up, to the top side of a silicon wafer. The top side of the wafer and all but peripheral portions of the attached chip(s) are then coated with an etch-resistant layer. Subsequently, the chips are etched to form sloped edges between the active areas...

    A high pressure, short rise time pulse is generated by first pressurizing a arge chamber utilizing a pressure fluid. An initially closed channel communicates the large chamber with a small test chamber that is closed except for the channel and to which one or more pressure gauges are connected. One of the pressure...
