Tezzaron Semiconductor Assigned Patent(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., May 26 -- Tezzaron Semiconductor, Naperville, Ill., has been assigned a patent (8,183,127) developed by Robert Patti, Warrenville, Ill., Sangki Hong, Singapore, and Ramasamy Chockalingam, Singapore, for a "method for bonding wafers to produce stacked integrated circuits." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A basic building block for wafer scale stacked integrated circuits is disclosed. The building block includes an integrated circuit device having an integrated circuit substrate having a circuit layer sandwiched between a buffer layer and a dielectric layer. The dielectric layer has a top side and a bottom side, the bottom side being in contact with the circuit layer. The top surface of the dielectric layer includes a plurality of pads. Each pad extends above the top surface by a predetermined distance. The pads have dimensions that reduce irregularities in the top surface of the pads. In addition, the pads are arranged in a manner to promote planarization of the surface of the wafer via CMP." The patent application was filed on May 24, 2010 (12/786,273).
