Latest Patents

One of his latest patents involves trenching techniques for forming channels, vias, and components. This patent discloses methods for creating a channel partially through and a via completely through the insulating layer of a substrate. With additional steps, the channel can form an electrically conductive line, an electrode of an integrated capacitor, or an optical waveguide. Another notable patent is a method for detecting the completion of electrolessly depositing metal into a via. This method includes using a non-autocatalytic detection mask with an opening over a via containing an autocatalytic material. The process involves electrolessly depositing a conductive metal into the via, which does not plate to the mask until the metal in the via contacts the mask, resulting in a change in the electrochemical potential of the mask.
