Abstract:
A bottom gate thin film transistor and a method for manufacturing the same are provided to improve the field effect mobility characteristic thereof by forming a lateral grown polycrystalline channel region. A bottom gate electrode(12) is formed on a substrate(10). A gate insulating layer(14) is formed on the substrate in order to cover the bottom gate electrode. An amorphous semiconductor layer, an N type semiconductor layer, and an electrode layer are sequentially formed on the gate insulating layer. A part of the amorphous semiconductor layer is exposed by etching sequentially a part of the electrode layer and a part of the N type semiconductor layer positioned on the gate electrode. The exposed amorphous semiconductor layer is molten by performing a laser annealing process. A lateral grown polycrystalline channel region is formed by crystallizing the molten amorphous channel region.

Abstract:
A fabrication method of a ZnO semiconductor thin film and a thin film transistor using the fabrication method are provided to enlarge a margin of the thin film transistor and the ZnO semiconductor thin film. A fabrication method of a ZnO semiconductor thin film includes the steps of: depositing a pure ZnO target without dopants in an oxygen atmosphere on a substrate(a); forming a diffusion layer made of oxygen-friendly metal on the entire surface or some part of the ZnO thin film(b); and diffusing oxygen included in the ZnO thin film by performing annealing for lowering oxygen concentration of the ZnO thin film and giving a characteristic of a semiconductor to the ZnO thin film(c). An oxidation of a diffusing layer is controlled by the temperature and time of the annealing.
Abstract:
An apparatus and a method for inputting characters of a mobile terminal are provided to facilitate implementation and reduce a system load by removing the necessity of a dictionary database and a dictionary search algorithm. A keypad(208) includes characters grouped to multiple character sets, in which representative characters of respective character sets are marked on corresponding keys. When a key with a representative character marked is inputted, a display unit(210) displays characters belonging to a character set of the marked representative key of the inputted key and outputs a selective indication to one of the displayed characters. When a shift key is inputted, a controller(210) counts an input duration of the shift key and sequentially moves the selective indication, and when the input of the shift key is released, the controller(200) inputs a character on which the selective indication is currently positioned.
Abstract:
An apparatus and a method for providing location information-based advertisement information using a broadband wireless access communication system are provided to transmit quality advertisement information better than a service using a mobile communication network by transmitting it through a broadband wireless access communication network. A store terminal(320) provides advertisement target information to a provider server(340). The provider server(340) uses the advertisement target information as charging target information, and provides load guidance information to a user terminal(310). A base station(330) receives the advertisement target information from the provider server, broadcasts or selectively transmits it to the user terminal, and transmits load guidance approval information from the user terminal to the provider server. The user terminal receives the advertisement target information from the base station, receives the road guidance information from the provider server and drives a load guidance function.

Abstract:
A single crystalline with a controlled orientation is provided to fabricate high quality nano-wire and transistor on a substrate by forming nano-wire in parallel on a substrate while using a crystalline material like Si, SiGe and the like. A template layer is formed on a substrate(100) made of silicon or sapphire, including a first lateral surface and a second surface confronting the first lateral surface. Pores are formed between the first and the second lateral surfaces of the template layer, having a first opening in the first lateral surface. A single crystalline material layer comes in contact with the first opening formed in the first lateral surface of the template layer. After a second opening connected to the pore formed in the second lateral surface is formed, a crystalline growth material of gas state is supplied through the second opening to form a crystalline wire in the pore by crystalline growth from the single crystalline material layer. The crystalline wire is made of silicon or silicon germanium.
Abstract:
A system and a method for providing subscriber information by using standby time in a mobile communication system are provided to solve the tedium of call standby time and to construct a new terminal/system profit model by providing a called subscriber's basic information and associated information during the call waiting time. A called terminal accesses a standby time saving server, registers subscriber information, joins a standby time information service, and establishes an open level for subscriber information(501). An MSC(Mobile Switching Center), if a call request message is received from a calling terminal(503), requests the standby time saving server to transmit called subscriber information(505). Receiving called subscriber information, the MSC checks whether the received called subscriber information is matched with a call ID(507). If matched, the MSC creates standby time information using the received called subscriber information and transmits it to the calling terminal. At the same time, the MSC forwards the call request message to the called terminal(509).
