Abstract: Forces applied to the channel regions of semiconductor slabs in a first direction relative to the semiconductor slab, can create strains in the crystal structure that improve carrier mobility to improve drive strength in the channel region. In a three-dimensional (3D) FET structure, a work function metal layer is provided on opposing faces of semiconductor slabs to cause a force to be exerted on the channel regions in a first direction corresponding to current flow. The force in the first direction is either tensile force or compressive force, depending on a FET type (N or P) employing the semiconductor slab, and is provided to create strain in a crystalline structure of the semiconductor slab to improve carrier mobility in the channel region. Increasing carrier mobility in the channel regions in a 3D FET structure increases drive strength of the 3D FET, which saves area in an integrated circuit.

Abstract: Techniques for improving the performance of an autonomous vehicle (AV) by automatically annotating objects surrounding the AV are described herein. A system can obtain sensor data from a sensor coupled to the AV and generate an initial object trajectory for an object using the sensor data. Additionally, the system can determine a fixed value for the object size of the object based on the initial object trajectory. Moreover, the system can generate an updated initial object trajectory, wherein the object size corresponds to the fixed value. Furthermore, the system can determine, based on the sensor data and the updated initial object trajectory, a refined object trajectory. Subsequently, the system can generate a multi-dimensional label for the object based on the refined object trajectory. A motion plan for controlling the AV can be generated based on the multi-dimensional label.

Abstract: Generally, the disclosed systems and methods implement improved detection of objects in three-dimensional (3D) space. More particularly, an improved 3D object detection system can exploit continuous fusion of multiple sensors and/or integrated geographic prior map data to enhance effectiveness and robustness of object detection in applications such as autonomous driving. In some implementations, geographic prior data (e.g., geometric ground and/or semantic road features) can be exploited to enhance three-dimensional object detection for autonomous vehicle applications. In some implementations, object detection systems and methods can be improved based on dynamic utilization of multiple sensor modalities. More particularly, an improved 3D object detection system can exploit both LIDAR systems and cameras to perform very accurate localization of objects within three-dimensional space relative to an autonomous vehicle.
