20080242002 | Apparatus and Methods for Cooling Semiconductor Integrated Circuit Package Structures - The present invention relates generally to apparatus and methods for cooling semiconductor integrated circuit (IC) chip package structures. More specifically, the present invention relates to apparatus and methods for thermally coupling semiconductor chips to a heat conducting device (e.g., copper thermal hat or lid) using a compliant thermally conductive material (e.g., thermal paste), wherein a thermal interface is designed to prevent/inhibit the formation of voids in the compliant thermally conductive material due to the flow of such material in and out from between the chips and the heat conducting device due to thermal cycling. | 10-02-2008 |
20080282742 | DEVICES AND METHODS FOR SIDE-COUPLING OPTICAL FIBERS TO OPTOELECTRONIC COMPONENTS - Optical devices, components and methods for mounting optical fibers and for side-coupling light to/from optical fibers using a modified silicon V-groove, or silicon V-groove array, wherein V-grooves, which are designed for precisely aligning/spacing optical fibers, are “recessed” below the surface of the silicon. Optical fibers can be recessed below the surface of the silicon substrate such that a precisely controlled portion of the cladding layer extending above the silicon surface can be removed (lapped). With the cladding layer removed, the separation between the fiber core(s) and optoelectronic device(s) can be reduced resulting in improved optical coupling when the optical fiber silicon array is connected to, e.g., a VCSEL array. | 11-20-2008 |
