Abstract: A tensile strained silicon layer is patterned to form a first group of fins in a first substrate area and a second group of fins in a second substrate area. The second group of fins is covered with a tensile strained material, and an anneal is performed to relax the tensile strained silicon semiconductor material in the second group of fins and produce relaxed silicon semiconductor fins in the second area. The first group of fins is covered with a mask, and silicon-germanium material is provided on the relaxed silicon semiconductor fins. Germanium from the silicon germanium material is then driven into the relaxed silicon semiconductor fins to produce compressive strained silicon-germanium semiconductor fins in the second substrate area (from which p-channel finFET devices are formed). The mask is removed to reveal tensile strained silicon semiconductor fins in the first substrate area (from which n-channel finFET devices are formed).

Abstract: A semiconductor package having an aperture in a die pad and solder in the aperture coplanar with a surface of the package is disclosed. The package includes a die pad, a plurality of leads, and a semiconductor die coupled to the die pad with a die attach material. A cavity or aperture is formed through the die pad to expose a portion of the die attach material. Multiple solder reflows are performed to reduce the presence of voids in the die attach material. In a first solder reflow, the voids of trapped gas that form when attaching the die to the die pad are released. Then, in a second solder reflow, solder is added to the aperture coplanar with a surface of the die pad. The additional solder can be the same material as the die attach material or a different material.

Abstract: A vacuum channel transistor having a vertical gate-all-around (GAA) architecture provides high performance for high-frequency applications, and features a small footprint compared with existing planar devices. The GAA vacuum channel transistor features stacked, tapered source and drain regions that are formed by notching a doped silicon pillar using a lateral oxidation process. A temporary support structure is provided for the pillar during formation of the vacuum channel. Performance of the GAA vacuum channel transistor can be tuned by replacing air in the channel with other gases such as helium, neon, or argon. A threshold voltage of the GAA vacuum channel transistor can be adjusted by altering dopant concentrations of the silicon pillar from which the source and drain regions are formed.

Abstract: Motion activity data is collected from at least one sensor. An initial motion activity classifier function is applied to the motion activity data to produce an initial motion activity posteriorgram. Pre-processing and segmenting the motion activity data into windows produces segmented motion activity data from which sensor specific features are extracted. An updated motion activity classifier function is generated from the extracted sensor specific features. Subsequent motion activity data is also collected from the at least one sensor, and the updated motion activity classifier function is applied to the subsequent motion activity data to produce an updated motion activity posteriorgram.

Abstract: A leadframe having extensions around an outer edge of a die pad are disclosed. More specifically, leadframes are created with a flange formed at the outer edge of the die pad and extending away from the die pad. The flange is bent, such that it is positioned at an angle with respect to the die pad. Leadframes are also created with anchoring posts formed adjacent the outer edge of the die pad and extending away from the die pad. The anchoring posts have a central thickness that is less than a thickness of first and second portions opposite the central portion. When the leadframe is incorporated into a package, molding compound completely surrounds each flange or anchoring post, which increases the bond strength between the leadframe and the molding compound due to increased contact area. The net result is a reduced possibility of delamination at edges of the die pad.

Abstract: The present disclosure is directed to a micro module with a support structure. The micro module includes a carrier substrate having contacts and a bonding pad, a semiconductor die, and a support structure. The semiconductor die is positioned on the bonding pad and is electrically coupled to the contacts. The support structure is positioned on the bonding pad and adjacent to the semiconductor die. The support structure reinforces the bonding pad such that the bonding pad is more rigid than flexible. As a result, an external force applied to the micro module is less likely to cause the micro module to bend and damage the semiconductor die.

Abstract: A method and apparatus for performing a low-power presence check are provided. In the method and apparatus, a controller detects a presence of a tag by at least causing the antenna to generate a magnetic field over a first time period for detecting the tag, measuring an antenna voltage over a second time period, causing the antenna to cease generating a magnetic field over a third time period longer than the first time period and comparing the antenna voltage to an antenna reference voltage to determine whether the tag is present. The controller detects the presence of the tag in response to receiving a command from a host device for performing the low-power presence check. The command may be a one-time command for every presence check stage or a command that is repeatedly received each time the controller detects the presence of the tag.

Abstract: An interconnect structure for use in coupling transistors in an integrated circuit is disclosed, including various configurations in which ferroelectric capacitors exhibiting negative capacitance are coupled in series with dielectric capacitors. In one embodiment, the negative capacitor includes a dielectric/ferroelectric bi-layer. When a negative capacitor is electrically coupled in series with a conventional dielectric capacitor, the series combination behaves like a stable ferroelectric capacitor for which the overall capacitance can be measured experimentally, and tuned to a desired value. The composite capacitance of a dielectric capacitor and a ferroelectric capacitor having negative capacitance coupled in series is, in theory, infinite, and in practice, very large. A series combination of positive and negative capacitors within a microelectronic interconnect structure can be used to make high capacity DRAM memory cells.

Abstract: A distributed computing system for artificial intelligence in autonomously appreciating a circumstance context of a smart device. Raw context data is detected by sensors associated with the smart device. The raw context data is pre-processed by the smart device and then provided to a cloud based server for further processing. At the cloud based server, various sets of feature data are obtained from the pre-processed context data. The various sets of feature data are compared with corresponding classification parameters to determine a classification of a continuous event and/or a classification of transient event, if any, which occur in the context. The determined classification of the continuous event and the transient event will be used to autonomously configure the smart device or another related smart device to fit the context.

Abstract: Disclosed herein is a system for detecting rotational speed and early failures of an electronic device. The system includes a rotating disk affixed to a rotating shaft of the electronic device. The rotating disk has projections extending from its periphery. A time of flight ranging system determines distance to the projections extending from the rotating disk. Processing circuitry determines a rotational speed of the rotating shaft from the determined distances to the projections extending from the rotating disk, and detects whether the electronic device is undergoing an early failure from the determined distances to the projections extending from the rotating disk. Rotational speed is determined from the time between successive peaks in the determined distances, and early failures (for example, due to wobble of the shaft) are determined where the peaks vary unexpectedly in magnitude.
