  • Patent number: 9673064
    Abstract: A lattice structure is formed in a non-silicon interposer substrate to create large cells that are multiples of through hole pitches to act as islands for dielectric fields. Each unit cell is then filled with a dielectric material. Thereafter, holes (i.e., through holes or blind holes) are created within the dielectric material in the cells. After hole formation, a conductive metal is formed into each of the holes providing an interposer. This method can enable fine pitch processing in organic-based materials, isolates the thermal coefficient of expansion (TCE) stress from metal vias to low TCE carriers and creates a path to high volume, low costs components in panel form.

  • Patent number: 9653772
    Abstract: A resonator includes a laminate, an inductive element on the laminate, and a semiconductor die attached to the inductive element and the laminate. The semiconductor die includes a substrate and a device layout area. The device layout area is separated into a number of device layout sub-areas, each of which has an area between about 1.0 ?m2 and 100.0 ?m2. By limiting the area of each one of the device layout sub-areas with the charge carrier trap trenches, the total area of the semiconductor die prone to inducement of eddy currents (i.e., the layer of accumulated charge at the interface of the substrate and the device layout area) is reduced, which in turn reduces interference with the magnetic field of the inductive element and thus improves the performance of the resonator.

  • Patent number: 9634007
    Abstract: Trench-confined selective epitaxial growth process in which epitaxial growth of a semiconductor device layer proceeds within the confines of a trench. In embodiments, a trench is fabricated to include a pristine, planar semiconductor seeding surface disposed at the bottom of the trench. Semiconductor regions around the seeding surface may be recessed relative to the seeding surface with Isolation dielectric disposed there on to surround the semiconductor seeding layer and form the trench. In embodiments to form the trench, a sacrificial hardmask fin may be covered in dielectric which is then planarized to expose the hardmask fin, which is then removed to expose the seeding surface. A semiconductor device layer is formed from the seeding surface through selective heteroepitaxy. In embodiments, non-planar devices are formed from the semiconductor device layer by recessing a top surface of the isolation dielectric.
