Latest Patents

One of his latest patents is titled "Apparatus and method for tape bonding." This invention describes a bonding apparatus designed for eutectically bonding tape leads to semiconductors and other substrates. The apparatus includes four separate bonding rails that apply heat, with a preselected distribution of mass along their length to compensate for uneven heating characteristics typically observed in linear heating elements. By arranging four heat elements orthogonally at the bottom ends of four electric power buses, the invention achieves substantially uniform heating, which is critical for forming eutectic bonds properly.

Another significant patent is "Semiconductor structure having alpha particle resistant film and method." This invention involves applying a prepatterned film of alpha particle resistant material, such as polyimide, to a semiconductor wafer. The film is strategically placed to cover only critical areas affected by alpha particle impingement, ensuring that bond pads and scribe streets remain uncovered.
