JDS Uniphase Assigned Patent


(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., July 9 -- JDS Uniphase, Milpitas, Calif., has been assigned a patent (8,475,056) developed by seven co-inventors for a semiconductor device assembly. The co-inventors are Prasad Yalamanchili, Santa Clara, Calif., Xiangdong Qiu, Cupertino, Calif., Reddy Raju, Fremont, Calif., Jay A. Skidmore, San Jose, Calif., Michael Au, Fremont, Calif., Laura Zavala, Mountain view, Calif., and Richard L. Duesterberg, Mountain View, Calif.



The abstract of the patent published by the U.S. Patent and Trademark Office states: "A fiber coupled semiconductor device having an improved optical stability with respect to temperature variation is disclosed. The stability improvement is achieved by placing the platform holding the semiconductor chip and the optical fiber onto a spacer mounted on a base. The spacer has an area smaller than the area of the platform, for mechanical decoupling of thermally induced deformation of the base from a deformation of the platform of the semiconductor device. Attaching the optical fiber to a vertical mounting surface of a fiber mount, and additionally attaching the fiber mount to a submount of the semiconductor chip further improves thermal stability of the packaged device." The patent application was filed on July 26, 2010 (12/843,823).
