Abstract: According to an exemplary embodiment, a method of forming a vertical device is provided. The method includes: providing a protrusion over a substrate; forming an etch stop layer over the protrusion; laterally etching a sidewall of the etch stop layer; forming an insulating layer over the etch stop layer; forming a film layer over the insulating layer and the etch stop layer; performing chemical mechanical polishing on the film layer and exposing the etch stop layer; etching a portion of the etch stop layer to expose a top surface of the protrusion; forming an oxide layer over the protrusion and the film layer; and performing chemical mechanical polishing on the oxide layer and exposing the film layer.

Abstract: An automatic vendor system used in hotels is provided, comprising: automatic vending machines each having a man-machine interaction interface, being used as vending and pickup platforms; a host being configurable for operation control, monitoring and storing information, which has a plurality of automatic vendor and management functions; a plurality of local shopping networks are formed and arranged in a hotel to generate a chain store network in an area through connection of computer network; through a information transfer link of production-direct marketing constructed with the sales information from the local networks, shortage of goods in a day is collected so as to supplement goods in the single vending machines; customers select goods through a touch screen after receiving an electronic cash card, then the host inquires cash amount through the reader and send an delivery instruction to the control board, the control board records and subtracts quantity of the purchased goods, and control a corresponding

Abstract: An animation embedded automatic vending machine is provided, comprising: a core board having a chip with high video playing capability; a 3D animation system for simulating the scene of a customer entering into a store to do shopping; a sales system supporting charge, computation, data storage and financial report printing; the 3D animation system is embedded into a shopping procedure control module; the sales system is connected to corresponding ports of the core board respectively, a display screen arranged on a man-machine interaction interface of the automatic vending machine, and a FPGA control bottom board, are connected to the core board of the automatic vending machine respectively, and the FPGA control bottom board instructs a delivery executing mechanism of the automatic vending machine to deliver the goods selected via the animation window.
