摘要:
Methods of forming a semiconductor device having a metal gate electrode include sequentially forming a gate insulator, a gate polysilicon layer and a metal-gate layer on a semiconductor substrate. The metal-gate layer and the gate polysilicon layer are sequentially patterned to form a gate pattern comprising a stacked gate polysilicon pattern and a metal-gate pattern. An oxidation barrier layer is formed to cover at least a portion of a sidewall of the metal-gate pattern.

In an array substrate and a display apparatus, a pixel part has a plurality of gate lines, a plurality of data lines, and a plurality of pixels electrically connected to the gate and data lines. A driving circuit drives the pixel part electrically connected to a first end of the gate lines. An inspection circuit is electrically connected to a second end of the gate lines, and inspects the pixel part in response to an inspection signal externally provided. Thus, positions and causes for defects of the pixel part may be accurately detected, thereby improving inspecting efficiency.

A gate driver includes multiple stages. Each stage has a circuit portion and a wiring portion. The wiring portion delivers first and second clock signals to the circuit portion. Further, the wiring portion includes first and second clock wirings receiving the first and second clock signal, respectively, first connecting wirings electrically connecting the first clock wiring with a first every other stage, and second connecting wirings electrically connecting the second clock wiring with the odd-numbered stages. Further, the wiring portion includes third connecting wirings electrically connecting the first connecting wiring with a second every other stage and fourth connecting wirings electrically connecting the second connecting wiring with the even-numbered stages. This configuration may prevent the gate driver from operating erroneously and reduce power consumed by the gate driver.

An apparatus and method for creating a data path for a broadcasting service in a cellular network is provided. In a method for creating a data path to provide a broadcasting service in a cellular network, a broadcast server transmits a session start request message to an Access Service Network-GateWay (ASN_GW) before transmission of Multicast and Broadcast Service (MBS) data, to request a multicast connection setup. The ASN_GW establishes a multicast connection between the broadcast server and the ASN_GW on the basis of information of the session start request message. The ASN_GW transmits a session start response message to the broadcast server in response to the session start request message, after establishment of the multicast connection between the broadcast server and the ASN_GW. The ASN_GW transmits a path registration request message to at least one base station associated with a broadcast zone, to request MBS data path establishment and air resource reservation. The base station establishes a multicast connection between the ASN_GW and the base station on the basis of information of the path registration request message. The base station transmits a path registration response message to the ASN_GW in response to the path registration request message, after establishment of the multicast connection between the ASN_GW and the base station.
