Abstract: A semiconductor device and a method of forming the same are provided. The semiconductor device includes a substrate, a gate structure, a dielectric structure and a contact structure. The substrate has source/drain (S/D) regions. The gate structure is on the substrate and between the S/D regions. The dielectric structure covers the gate structure. The contact structure penetrates through the dielectric structure to connect to the S/D region. A lower portion of a sidewall of the contact structure is spaced apart from the dielectric structure by an air gap therebetween, while an upper portion of the sidewall of the contact structure is in contact with the dielectric structure.

Abstract: A foldable sales terminal includes at least one sale operation interface and a mainframe module. The sale operation interface is a flat panel, and the outward surface thereof is provided with a touch display panel. The sale operation interface is connected to the mainframe module via a pivot connection portion. The mainframe module is provided with a mainboard disposed therein and one side, away from the pivot connection portion, of the mainframe module has an output/input connection port, so that the sale operation interface and the mainframe module can rotate relative to each other to change the angle therebetween, allow the sale operation interface fold to cover inward the mainframe or open outwards far away from the mainframe. The design is simple and effective, such that the sales terminal can be folded to reduce the volume thereof for conveniently packaging, storing, carrying, and transporting the sales terminal.

Abstract: A general-purpose computer control system for an automatic vending machine, that includes: a general-purpose conversion and control module, a data integration conversion unit, an automatic vending machine control unit, a wireless transmission unit, an encryption protection unit, and a plurality of connection ports. On the general-purpose conversion and control module is disposed a first general-purpose connection end, for connecting to the automatic vending machine. Wherein, in the data integration conversion unit is disposed a central processing unit (CPU), to perform data connection and conversion between the CPU and the automatic vending machine control unit. The automatic vending machine control unit is used to control the operations inside the automatic vending machine. The wireless transmission unit is used to perform data transmission and verification for a remote end. The encryption protection unit is used to perform data encryption for the automatic vending machine.

Abstract: An assembled type sales terminal comprises: a flat panel sales terminal and a printer. The flat panel sales terminal includes: an operation display screen, disposed at one end of the flat panel sales terminal; an expansion assembling seat, disposed rotatably at the other end of the flat panel sales terminal, and connected thereto through using a hinge; and a first connection portion, disposed on a lower portion of the expansion assembling seat. The printer includes: a lift cover, having a paper roll placement port disposed thereon; a second connection portion, disposed on the printer, to work in cooperation with the first connection portion; and a placement plane, disposed at a lower portion of the printer. The flat panel sales terminal can be stacked on the printer to form into a body; or the former and the latter can be separated and juxtaposed side by side.

Abstract: A fast detachable placement seat structure for a display, that comprises: a flat panel display and a placement seat. The placement seat includes: a support plate, a bottom seat, a cable placement portion, and a fast detachable mechanism. The fast detachable mechanism includes at least a fastening portion, and at least a locking portion. The flat panel display is disposed in an electronic device. The bottom base is connected to the support plate to form an angle with the support plate, and is used for receiving circuits. The flexible design mentioned able is able to achieve fewer components required, simple structure, easy assembly/detachment, to save time for assembly and repair, and reduce production cost significantly. As such, that fast detachable placement seat structure for a display can be used in various electronic products having flat panel displays.

Abstract: An enhanced heat dissipation module having multi-layer heat isolation, made of copper, aluminum, iron, or a combination thereof, includes a protection box, used to receive an electric circuit board. On protection box is provided with at least a notch corresponding to high heat generating electronic components on the electric circuit board. A heat dissipater is provided with a large heat dissipation area disposed opposite to protection box, and it includes at least a fix seat disposed in protrusion on the heat dissipater. The fix seat extends into the notch of the protection box, to contact fully surface of the high heat generating electronic components. An elastic contact plate, disposed in front of the fix seat, to press against surface of the high heat generating electronic components. A plurality of heat conduction tubes are pressed onto the heat dissipater, with one end connected to the fix seat.
