Abstract: The present disclosure provides a semiconductor device that includes a semiconductor fin disposed over a substrate, an isolation structure at least partially surrounding the fin, an epitaxial source/drain (S/D) feature disposed over the semiconductor fin, where an extended portion of the epitaxial S/D feature extends over the isolation structure, and a silicide layer disposed on the epitaxial S/D feature, where the silicide layer covers top, bottom, sidewall, front, and back surfaces of the extended portion of the S/D feature.

Abstract: A braking precautionary system for a vehicle includes a speed controller electrically connected to a speed sensor for sensing a driving speed of the vehicle and operatively outputing an electric current to actuate a relay when the driving speed exceeds a predetermined value as preset in the speed controller for turning on a controller switch connected to a warning lamp circuit having a warning lamp juxtapositioned to a brake lamp of the vehicle; and an accelerator-pedal contactor switch electrically connected to the warning lamp circuit and operatively switched on when releasing the accelerator pedal, whereby upon releasing of the accelerator pedal for deceleration and just before depressing the brake pedal, the warning lamp of the warning lamp circuit will be lit before the lighting of a brake lamp for precautioning the rear car for ensuring driving safety.
