Abstract: The present application provides a semiconductor device and the method of making the same. The method includes recessing a fin extending from a substrate, forming a base epitaxial feature on the recessed fin, forming a bar-like epitaxial feature on the base epitaxial feature, and forming a conformal epitaxial feature on the bar-like epitaxial feature. The forming of the bar-like epitaxial feature includes in-situ doping the bar-like epitaxial feature with an n-type dopant at a first doping concentration. The forming of the conformal epitaxial feature includes in-situ doping the conformal epitaxial feature with a second doping concentration greater than the first doping concentration.

Abstract: A mechanism for mounting an electronic device to a ceiling or a wall includes a fixing seat with a mounting hole, a trigger button in the mounting hole, two clamping members slidably connected to the fixing seat, and two first elastic members. The clamping members abut opposing ends of the first positioning portion when the trigger button is at a first position, and the clamping members move toward each other by a resilient force when the trigger button moves toward the second position. In a second position two ends of the fixing member are clamped, thereby the electronic device is mounted firmly and stably to the fixing member. An electronic device having the mounting mechanism is also disclosed.

Abstract: An electronic device with inbuilt mounting mechanism includes a first housing defining a first receiving hole, a second housing defining a second receiving hole, and a mounting mechanism. The mounting mechanism includes a rotary plate, a driving rod, and two clamping members which can slide. The driving rod includes a cam-shaped portion and a rod portion. The rod portion is connected to the rotary plate and the two clamping member move toward each other when the cam-shaped portion is rotated by the rotary plate. The two clamping members cooperatively clamp a fixing member to mount the electronic device to the fixing member.

Abstract: An electronic device with anti-disassembly structure includes a top cover having a first set of serrated teeth and a first through hole, a fastener receiver having a posting head and a posting body, a fixed disk having a fourth set of serrated teeth, an elastic member, a bottom cover having a second through hole, and a fastener. The posting head has a second set of serrated teeth and a third set of serrated teeth. When the top cover is separated from the bottom cover, the elastic member is compressed by the external force, and the second set of serrated teeth is separated with the first set of serrated teeth, the third set of serrated teeth engage with the fourth set of serrated teeth, and the fastener is rotated to detached from the bottom cover.

Abstract: A moored balloon includes a balloon, a wire coupled to the balloon, an antenna, a cable coupled to the balloon, a rotating device hung below the balloon, and a fixing device. The rotating device comprises a rotating unit and a bracket. The rotating unit comprises a bearing seat mounted on the bracket, a bearing unit mounted on the bearing seat, and a shaft passing through the bearing unit and coupled to the balloon. The fixing device comprises a receiving tube for receiving the antenna. The receiving tube is located on the bracket. The shaft moves with the balloon to generate a twisting force, the bearing unit counterbalances the twisting force to prevent the cable being twisted with the wires.

Abstract: An electronic device includes an enclosure defining a first receiving hole and a locking assembly. The first receiving hole defines a first passing portion and a first locking portion smaller than and communicating with the first passing portion. The locking assembly includes a fixed member fixed to the enclosure and a rubber cover tightly sandwiched between the fixing member and the enclosure. The rubber cover includes a block portion extending to and received in the first passing portion of the first receiving hole. When a fastener on a wall is positioned at the first locking portion by way of the first passing portion, the block portion of the rubber cover blocks the first passing portion to prevent the fastener from moving away the first locking portion.

Abstract: A housing includes a wall, a connector, a coupler, and a foot pad. The housing includes a bottom surface, a recess defined in the bottom surface, and a discontinuous ring-shaped engagement member surrounding the recess. The engagement member has a first gap and a second gap aligned with the first gap. The connector is connected to the engagement member and is rotatably engaged in the first gap. The coupler includes a main body and an engagement portion extending from a circumference surface thereof. A first engagement hole defined in a central portion of the main body. The main body is rotatably connected to the connector and engagable in the recess. The engagement portion engages in the second gap. The foot pad is connected to the coupler to seal the first engagement hole and received in the recess.
