Latest Patents

Lei Li holds 2 patents that showcase his innovative approach. His latest patents include a "Structure and method for contact pads having a recessed bondable metal plug over copper-metallized integrated circuits." This invention features a metal structure for an integrated circuit, which has copper interconnecting metallization protected by an overcoat layer. A portion of the metallization is exposed in a window opened through the thickness of the overcoat layer. The design includes a patterned conductive barrier layer positioned on the copper metallization, forming a trough with walls conformal with the overcoat window. The height of the wall is less than the overcoat thickness, creating a step. A plug of bondable metal, preferably aluminum, is positioned in the trough, matching the trough wall height.

Another notable patent is the "Structure and method for contact pads having a protected bondable metal plug over copper-metallized integrated circuits." This integrated circuit features copper interconnecting metallization protected by a first inorganic overcoat layer, with portions of the metallization exposed in windows opened through the thickness of the first overcoat layer. A patterned conductive barrier layer is positioned on the exposed portion of the copper metallization and on portions of the first overcoat layer surrounding the window. A bondable metal layer is placed on the barrier layer, suitable for wire bonding, while a second organic overcoat layer surrounds the window, ensuring the surface of this layer is at or above the bondable layer's surface.
