Abstract:
A method for preparing a ZnO nanocrystal directly on a silicon substrate includes the steps of: (S1) forming a Zn—Si—O composite thin film on the silicon substrate; and (S2) thermally treating the obtained thin film. Particularly, ZnO nanocrystals are formed in an amorphous Zn—Si—O composite thin film by controlling the composition of the Zn—Si—O composite thin film and heating temperature thereof. With the present invention method for preparing a ZnO nanocrystal directly on a silicon substrate, more possibilities are opened up for the applications of ZnO nanocrystals to an optoelectronic device in use of a silicon substrate.

Abstract:
A method for implementing a redundant structure of an ATCA system via a base interface of a network system based on an ATCA standard, and the ATCA system for use in the same are disclosed. Each of routing protocol shelves and LI shelves includes two ports connected to two IPC paths provided from the base interface, such that a representative IP address is assigned to a single port to be used, performs IPC communication using the representative IP address. If a port error or link-down state occurs, the representative IP address is assigned to the other port, resulting in the implementation of stable IPC communication. If the port error or link-down state occurs in an active-mode ShMC shelf, an IPC path passing through a standby-mode ShMC shelf is provided.

A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound.

Abstract:
Provided are non-volatile split-gate memory cells having self-aligned floating gate and the control gate structures and exemplary processes for manufacturing such memory cells that provide improved dimensional control over the relative lengths and separation of the split-gate elements. Each control gate includes a projecting portion that extends over at least a portion of the associated floating gate with the size of the projecting portion being determined by a first sacrificial polysilicon spacer that, when removed, produces a concave region in an intermediate insulating structure. The control gate is then formed as a polysilicon spacer adjacent the intermediate insulating structure, the portion of the spacer extending into the concave region determining the dimension and spacing of the projecting portion and the thickness of the interpoly oxide (IPO) separating the upper portions of the split-gate electrodes thereby providing improved performance and manufacturability.

A first conductive layer is formed on the semiconductor substrate having the first dielectric layer. A mask pattern is formed on the first conductive layer. Using the mask pattern as an etch mask, the first conductive layer is etched to form a first conductive pattern narrowing from its upper surface toward its middle portion. A second dielectric layer is formed on the semiconductor substrate having the first conductive pattern. A second conductive pattern crossing the active region adjacent to the first conductive pattern and partially covering the first conductive pattern is formed on the semiconductor substrate having the second dielectric layer.
