  • Patent number: 10541140
    Abstract: A process for metalizing a through silicon via feature in a semiconductor integrated circuit device, the process including, during the filling cycle, reversing the polarity of circuit for an interval to generate an anodic potential at said metalizing substrate and desorb leveler from the copper surface within the via, followed by resuming copper deposition by re-establishing the surface of the copper within the via as the cathode in the circuit, thereby yielding a copper filled via feature.

  • Patent number: 10514598
    Abstract: Vacuum-integrated photoresist-less methods and apparatuses for forming metal hardmasks can provide sub-30 nm patterning resolution. A metal-containing (e.g., metal salt or organometallic compound) film that is sensitive to a patterning agent is deposited on a semiconductor substrate. The metal-containing film is then patterned directly (i.e., without the use of a photoresist) by exposure to the patterning agent in a vacuum ambient to form the metal mask. For example, the metal-containing film is photosensitive and the patterning is conducted using sub-30 nm wavelength optical lithography, such as EUV lithography.

  • Patent number: 6890323
    Abstract: A small volume effusion trap for use with common surgical or medical instruments having a housing unit with two elongate, rigid, hollow members, a vacuum source, and a drainage tube. In an embodiment, a standard, commercially available sample vial attaches to the housing unit to collect the effusion. The sample vial can be utilized directly in standardized diagnostic and/or therapeutic analysis apparatuses. To collect a small volume of effusion, one elongate, rigid, hollow member is connected to standard surgical or medical aspirators and the other elongate, rigid, hollow member is connected to the vacuum line. With suction applied to the elongate, rigid, hollow member, an area of reduced pressure is produced in the sample vial so as to cause aspirated effusion to proceed from the surgical or medical apparatus through the elongate, rigid hollow member into the sample vial.
