Abstract: A method for manufacturing semiconductor device structure includes providing a substrate having a surface; forming a first gate structure on the surface; forming a second gate structure on the surface; forming a first well region in the substrate and between the first gate structure and the second gate structure; forming a conductive contact within a trench between the first gate structure and the second gate structure; forming a first structure in the first well region, wherein the first structure tapers away from a bottom portion of the conductive contact.

Abstract: This document describes techniques and systems related to tracking different sections of articulated vehicles. A vehicle uses a radar system that can discern between unarticulated vehicles and articulated vehicles, which by definition have multiple sections that can pivot in different directions for turning or closely following a curve. The radar system obtains detections indicative of another vehicle traveling nearby. When the detections indicate the other vehicle is articulated, the radar system tracks each identifiable section, rather than tracking all the sections together. A bounding box is generated for each identifiable section; the radar system separately and concurrently monitors a velocity of each bounding box. The multiple bounding boxes that are drawn enable the radar system to accurately track each connected section of the articulated vehicle, including to detect whether any movement occurs between two connected sections, for accurately localizing the vehicle when driving.

Abstract: The present disclosure provides a memory device and the forming method thereof. The memory device includes a gate structure on a substrate, a source/drain region in a substrate, a dielectric layer covering the substrate and the gate structure, and a cell contact adjacent to the gate structure. The cell contact includes a conductive layer, a first barrier layer on a sidewall of the conductive layer, and a second barrier layer on a bottom surface of the conductive layer. The second barrier layer directly contacts the first barrier layer and the source/drain region. A second resistivity of the second barrier layer is lower than a first resistivity of the first barrier layer.

Abstract: This document describes radar tracking with model estimates augmented by radar detections. An example tracker analyzes information derived using radar detections to enhance radar tracks having object measurements estimated from directly analyzing data cubes with a model (e.g., a machine-learning model). High-quality tracks with measurements to objects of importance can be quickly produced with the model. However, the model only estimates measurements for classes of objects its training or programming can recognize. To improve estimated measurements from the model, or even in some cases, to convey additional classes of objects, the tracker separately analyzes detections. Detections that consistently align to objects recognized by the model can update model-derived measurements conveyed initially in the tracks. Consistently observed detections that do not align to existing tracks may be used to establish new tracks for conveying more classes of objects than the model can recognize.
