    • Semiconductor devices including an isolation layer on a semiconductor substrate are provided. The isolation layer defines an active region of the semiconductor substrate. The device further includes an upper gate electrode crossing over the active region and extending to the isolation layer and lower active gate electrode. The lower active gate electrode includes a first active gate electrode extending from the upper gate electrode to the active region and a second active gate electrode below the first active gate electrode and having a greater width than a width of the first active gate electrode. The device further includes a lower field gate electrode that extends from the upper gate electrode to the isolation layer and has a bottom surface that is at a lower level than a bottom surface of the active gate electrode such that the sidewalls of the active region are covered below the lower active gate electrode. Related methods of fabricating semiconductor devices are also provided herein.
    • 提供包括半导体衬底上的隔离层的半导体器件。 隔离层限定半导体衬底的有源区。 该器件还包括与有源区交叉并延伸到隔离层和下活性栅电极的上栅电极。 下有源栅电极包括从上栅极延伸到有源区的第一有源栅电极和位于第一有源栅电极下方并且具有比第一有源栅电极的宽度更大的宽度的第二有源栅电极。 该器件还包括一个从上部栅电极延伸到隔离层的下部栅极电极,并且具有一底部表面,该底表面处于与该有源栅极电极的底表面相比较低的位置,使得该有源区域的侧壁被覆盖 在下部有源栅电极下方。 本文还提供了制造半导体器件的相关方法。

    • One or more vehicle steering measurements of a vehicle may be measured. One or more expected vehicle steering measurements may be calculated, each calculated expected vehicle steering measurement corresponding to one of the measured vehicle steering measurements. At least one difference between one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement may be calculated. A speed of the vehicle may be measured. One or more current threshold values may be calculated based on the measured speed, each of the current threshold values corresponding to one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement. An automatic vehicle control system may be deactivated when one or more of the calculated differences exceeds its corresponding current threshold value.
    • 可以测量车辆的一个或多个车辆转向测量值。 可以计算一个或多个预期的车辆转向测量值,每个计算的预期车辆转向测量值对应于所测量的车辆转向测量之一。 可以计算测量的车辆转向测量值中的一个与其对应的计算的预期车辆转向测量之间的至少一个差。 可以测量车辆的速度。 可以基于测量的速度来计算一个或多个当前阈值,每个当前阈值对应于所测量的车辆转向测量值之一和其对应的计算的预期车辆转向测量值。 当计算出的一个或多个差异超过其对应的当前阈值时,可以停用自动车辆控制系统。
