A semiconductor device having a contact barrier for insulating contacts with a large aspect ratio and having a fine pitch between adjacent conductive lines and a method of manufacturing the same are provided. The semiconductor device includes a buried contact formed in a region between two adjacent first conductive lines and two adjacent second conductive lines. Insulating lines define a width of the buried contact. To form the contact barrier, an interlayer dielectric layer formed on the second conductive lines is patterned to form a space and an insulating line having an etching ratio different from the interlayer dielectric layer is formed in the space. The interlayer dielectric layer is selectively wet etched relative to an insulating layer covering the second conductive line and the first insulating line to form buried contact hole. The buried contact hole is filled with conductive material to form a buried contact.

The present invention relates to a method for cluster based data in wireless sensor networks. The method includes: selecting any one of border nodes positioned at the edge of a cluster as a temporary cluster head as a temporary cluster head when a target is sensed in the cluster; bugging data of the temporary cluster head by border nodes in other adjacent cluster which do not sense the target to temporarily change the border node selected as the temporary cluster head to a cluster head of each of the border nodes; when the target is sensed by at least one of the border nodes, collecting data from each of the border nodes by the temporary cluster head to transferring the collected data to an actual cluster head of the temporary cluster head; and aggregating the collected data by actual cluster head of the temporary cluster head.

In a semiconductor device including a transistor having an embedded gate, and methods of manufacturing the same, a substrate is divided into first and second regions. A gate trench is formed in the first region, a first gate structure partially fills the gate trench and a passivation layer pattern is provided inside the gate trench and positioned on the first gate structure. A first source/drain is provided adjacent to sidewalls of the first gate structure. A second gate structure is provided in the second region and has a silicon oxide layer, a conductive layer pattern and a metal silicide layer pattern stacked on the conductive layer pattern. A second source/drain is provided adjacent to sidewalls of the second gate structure. Defects due to formation of reactants may be reduced in a formation process of the above-described semiconductor device, improving reliability and operating characteristics.
