Patents by Inventor Alex Riposan

Alex Riposan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9892890
    Abstract: A narrow sputtering source and target which are designed to be installed in a series on a sputtering chamber. Each of the narrow sputtering source has length sufficient to traverse one direction of the sputtering zone, but is much narrower than the orthogonal direction of the sputtering zone. When the sputtering chamber performs a pass-by sputtering process, each of the narrow sputtering sources is sufficiently long to traverse the sputtering zone in the direction orthogonal to the substrate travel direction, but is much narrower than the sputtering zone in the direction of substrate travel. Several narrow sputtering sources are installed so as to traverse the entire sputtering zone in all directions.

  • Patent number: 9525099
    Abstract: An arrangement for supporting substrates during processing, having a wafer carrier with a susceptor for supporting the substrate and confining the substrate to predetermined position. An inner mask is configured for placing on top of the substrate, the inner mask having an opening pattern to mask unprocessed parts of the substrate, but expose remaining parts of the substrate for processing. An outer mask is configured for placing on top of the inner mask, the outer mask having an opening that exposes the part of the inner mask having the opening pattern, but cover the periphery of the inner mask.

  • Patent number: 9502276
    Abstract: A system for processing substrates in plasma chambers, such that all substrates transport and loading/unloading operations are performed in atmospheric environment, but processing is performed in vacuum environment. The substrates are transported throughout the system on carriers. The system's chambers are arranged linearly, such that carriers move from one chamber directly to the next. A conveyor, placed above or below the system's chambers, returns the carriers to the system's entry area after processing is completed. Loading and unloading of substrates may be performed at one side of the system, or loading can be done at the entry side and unloading at the exit side.

  • Publication number: 20140332376
    Abstract: A system for depositing material from a target onto substrates, comprising a processing chamber; a sputtering target having length L and having sputtering material provided on front surface thereof; a magnet operable to reciprocally scan across the length L in close proximity to rear surface of the target; and a counterweight operable to reciprocally scan at same speed but opposite direction of the magnet.
