Abstract: A system for improving yield and increasing throughput on processes that remove flux and flux residues from openings between 3D semiconductor structures. The system employs high flow, directed, pressurized nitrogen to assist in de-wetting the areas between semiconductor devices where solder bumps or micro bumps attach one device to another.

Abstract: An electromagnetic-based ultrasonic residual stress relief system and process for welds on metal surfaces can include a latching switch for high voltage charging that controls current from the capacitor charging module to the high voltage capacitor, a non-latching switch for spark-gap trigger that can control current from a spark-gap trigger module to a spark-gap trigger circuit. The non-latching switch for spark-gap trigger can discharge energy from the high-pulsed current capacitor into the spark-gap circuit, which can discharge energy into a coil that can be moved over the weld zone. The large AC current induced high-frequency, small-amplitude through-thickness ultrasonic vibration yields residual stress relief in the weld and HAZ region.

Abstract: An immersion station for performing lift off of metals and other materials (e.g., organic or inorganic films) from a plurality of wafers comprises an immersion chamber having a conical bottom portion, a drain coupled thereto, a spray bar having nozzles adapted to spray chemical solvent at a high flow rate into the immersion chamber, and an immersion tool positioned within the chamber having a cassette with compartments for holding a plurality of wafers, wherein the immersion tool has openings for exposure to the chemical solvent spray.

Abstract: A remotely mountable weatherproof bi-directional, half-duplex switching amplifier system is designed to provide maximum range for low power half-duplex radios such as Spread Spectrum radio transceivers. This invention automatically senses when to go into the transmitter amplification mode and puts all the transmit power right at the antenna. In the receive mode, it provides low noise pre amplification of received signals at the antenna thereby minimizing or even eliminating the effects of the coaxial transmission line from the radio transceiver to the remote location of the antenna. The invention is preferred to be in a waterproof enclosure adjacent to the antenna mounted to a pole and powered by a DC injector and excited by a transceiver, both pole and injector located remote from the mounting pole and also includes an improved electrostatic overvoltage protection device.
