  • Patent number: 6708873
    Abstract: An apparatus and a method for filling high aspect ratio holes in electronic substrates that can be advantageously used for filling holes having aspect ratios larger than 5:1 are disclosed. In the apparatus, a filler plate and a vacuum plate are used in conjunction with a connection means such that a gap is formed between the two plates to accommodate an electronic substrate equipped with high aspect ratio via holes. The filler plate is equipped with an injection slot while the vacuum plate is equipped with a vacuum slot such that when a substrate is sandwiched therein, via holes can be evacuated of air and injected with a liquid simultaneously from a bottom side and a top side of the substrate. The present invention novel apparatus and method allows the filling of via holes that have small diameters, i.e., as small as 10 &mgr;m, and high aspect ratios, i.e.

  • Patent number: 6579149
    Abstract: A device and method for providing precision alignment and support for an optical film measurement probe in the wafer rinse tank of a CMP polish tool. The device includes of a probe carrier, and spring loaded support guides attached to a support ring that supports and locates the mechanism in the rinse tank of the CMP tool. The probe carrier has multiple beveled bearing pads (three or more) that contact the rim of the rotating wafer chuck. Pressure from the chuck against these pads forces the probe carrier to maintain a fixed distance and orientation relative to the wafer while allowing the smooth rotation and motion of the wafer and chuck. Further, an integrated the wafer spray nozzles can be attached to the probe carrier that is located so as to minimize interference between wafer spraying and the probe carrier.

  • Patent number: 6527158
    Abstract: The present invention discloses a method and apparatus for forming solder bumps by a molten solder screening technique in which a flexible die head constructed of a metal sheet is utilized for maintaining an intimate contact between the die head and a solder receiving mold surface. The flexible die head, when used in combination with a pressure means, is capable of conforming to any curved mold surface as long as the curvature is not more than 2.5 &mgr;m per inch of die length.

The present invention further provides a method and apparatus for filling a multiplicity of cavities in a mold surface by providing a stream of molten solder and then intimately contacting the surface of the molten solder with a multiplicity of cavities such that the molten solder readily fills the cavities. The apparatus further provides means for removing excess molten solder from the surface of the mold without disturbing the molten solder already filled in the cavities.

  • Patent number: 6362557
    Abstract: An actuator scaled to macroscopic or microscopic sizes, uses ultrasonic energy to induce motion of an object in a desired direction. The actuator includes one or more pair of piezoelectric transducers connected with a transducer tip. Supplying the piezoelectric transducers with alternating current electrical power causes the tip to vibrate at ultrasonic frequencies. Urging the vibrating tip into contact with a surface on the object at a selected angle of inclination induces the object to move in the desired direction at a rate determined by the inclination angle. Multiple actuators can be used to induce a fall range of movements of variously shaped objects. In microscopic form, the actuator can be used to create a MEMS device. The optional application of a compliant material either on the transducer tip or on the object's surface enhances the movement induced by the actuator.

  • Patent number: 6319093
    Abstract: A system and method that integrates film thickness measurements with a chemical-mechanical polishing (CMP) spin-dry tool. By doing so, each wafer can be measured as it comes out of the previous CMP process. Thickness measurement feedback is provided, which controls processing of the wafer and also monitor operational status of a CMP polishing unit prior to completion of the wafer being polished, resulting in significant cost and cycle time reduction through the elimination of tool infrastructure and wafer handling by assuring proper tolerances of the CMP polishing unit are maintained.
