Latest Patents

One of Hall's latest patents is titled "Ring isolated through-substrate vias for high resistivity substrates." This invention involves through-substrate vias (TSVs) that extend through a high resistivity semiconductor substrate, which are laterally spaced and isolated from an active device formed over the substrate by deep trench isolation (DTI) structures. The DTI structures may extend partially or entirely through the substrate and can include an air gap, entirely surrounding the active device and the TSVs. Another significant patent is "Controlling of etch depth in deep via etching processes." This patent relates to semiconductor structures and outlines a method to control the depth of etch in deep via etching. The method includes forming an interface within the substrate between an etch control dopant and the substrate material, etching a via within the substrate, and terminating the etching of the via at the interface upon detection of the interface.
