  • Patent number: 7560371
    Abstract: Methods of forming a conductive via in a substrate include contacting the substrate with a wave of conductive liquid material, such as molten solder, and drawing the liquid material into the aperture with a vacuum. The wave may be formed by flowing the liquid material out from an outlet in a direction generally against the gravitational field. The liquid material may be solidified to form an electrically conductive structure. A plurality of apertures may be selectively filled with the liquid material one at a time, and liquids having different compositions may be used to provide conductive vias having different compositions in the same substrate. Systems for forming conductive vias include a substrate fixture, a vacuum device having a vacuum fixture, and a solder-dispensing device configured to provide a wave of molten solder material. Relative lateral and vertical movement is provided between the wave of molten solder and a substrate supported by the substrate fixture.

  • Patent number: 7118783
    Abstract: CVD, ALD, and other vapor processes used in processing semiconductor workpieces often require volatilizing a liquid or solid precursor. Certain embodiments of the invention provide improved and/or more consistent volatilization rates by moving a reaction vessel. In one exemplary embodiment, a reaction vessel is rotated about a rotation axis which is disposed at an angle with respect to vertical. This deposits a quantity of the reaction precursor on an interior surface of the vessel's sidewall which is exposed to the headspace as the vessel rotates. Other embodiments employ drivers adapted to move the reaction vessel in other manners, such as a pendulum arm to oscillate the vessel along an arcuate path or a mechanical linkage which moves the vessel along an elliptical path.
