Abstract: The present disclosure provides a semiconductor device and a method of forming the same. A method according one embodiment of the present disclosure include forming a stack over a substrate, forming a fin-shape structure from patterning the stack and the substrate, recessing the fin-shape structure to form a source/drain trench, depositing a dielectric film in the source/drain trench with a top surface below a top surface of the substrate in the fin-shape structure, and forming an epitaxial feature over the dielectric film. A bottom surface of the epitaxial feature is below the top surface of the substrate in the fin-shape structure.

Abstract: A battery charger includes a first housing for holding a battery pack of a power hand tool to be charged, a second housing pivoted to the first housing and provided with a connector connectable to a power socket of a vehicle, a charging unit installed in the first housing and electrically connected to the connector for charging the inserted battery pack, a fastening device for locking the second housing to the first housing after adjustment of the angular position of the second housing relative to the first housing, and a spring member for holding the fastening device in the locking position.
