Latest Patents
One of Ryan's latest patents is titled "Silicon nitride passivation layer for covering high aspect ratio features." This patent describes a method of forming a passivation layer comprising silicon nitride on features of a substrate. In the first stage of the deposition method, a dielectric deposition gas, which includes a silicon-containing gas and a nitrogen-containing gas, is introduced into the process zone and energized to deposit a silicon nitride layer. In the second stage, a treatment gas with a different composition is introduced into the process zone and energized to treat the silicon nitride layer. The first and second stages can be performed multiple times to achieve the desired results.
Another significant patent is "Fabrication of through-silicon vias on silicon wafers." This method includes etching a plurality of through holes in a silicon plate. An oxide liner is deposited on the surface of the silicon plate and on the sidewalls and bottom wall of the through holes. A metallic conductor is then deposited in the through holes. In another version, which may be used concurrently with the oxide liner, a silicon nitride passivation layer is deposited on the exposed back surface of the silicon plate of the substrate.
