摘要:
Stress buffer layers for integrated microelectromechanical systems (MEMS) are described. For example, a semiconductor package includes a substrate having first and second surfaces, the second surface having an array of external conductive contacts. A microelectromechanical system (MEMS) component is disposed above the first surface of the substrate. A buffer layer is disposed above the MEMS component, the buffer layer having a first Young's modulus. A mold compound is disposed above the buffer layer, the mold compound having a second Young's modulus higher than the first Young's modulus.

A dual gate drain extension field effect transistor assembly comprises a first FET device having a source, a gate and a drain extension region. The first FET device's gate is electrically coupled to a constant voltage source. A second FET device has a source, a drain, and a gate, and the second FET's drain is electrically to the first FET's source.
摘要:
Reduced-profile semiconductor device apparatus are achieved by thinning a semiconductive device substrate at a backside surface to expose a through-silicon via pillar, forming a recess to further expose the through-silicon via pillar, and by seating an electrical bump in the recess to contact both the through-silicon via pillar and the recess. In an embodiment, the electrical bump contacts a semiconductor package substrate to form a low-profile semiconductor device apparatus. In an embodiment, the electrical bump contacts a subsequent die to form a low-profile semiconductor device apparatus.

A recording and/or reproducing device. A cassette, which contains a magnetic tape and a coupling element connected to the magnetic tape, can be loaded into the device. The device includes a pull-out element which can be coupled to the coupling element so as to form a pull-out assembly. The pull-out assembly can be moved to the reel hub of a take-up reel. A radial positioning structure is provided between the reel hub and the pull-out assembly. The radial positioning structure is formed by two projecting portions, of which a first projecting portion projects from the reel hub and the second projecting portion projects from the pull-out assembly.

摘要:
A package on a die having a low resistive substrate, wherein the package comprises an inductor on low-k dielectric and a capacitor on high-k dielectric. The stacked arrangement having different dielectric materials may provide an inductor having a high Q-factor while still having a high capacitance density. In addition, moving the inductor from the die to the package and fabricating the high density capacitor on the package reduces the silicon area required permitting smaller RF/analog blocks on the chip.

Some embodiments include packages and methods of making the packages. One of the packages includes a ground layer (e.g., a ground plane) of metal formed over a chip of die, an antenna element of metal formed over the ground layer, and a dielectric lens formed over the antenna element. The dielectric lens includes a plurality of dielectric layers that have graded dielectric constants in a decreasing order along a direction from the antenna element toward a top surface of the package.
