Provided are a method and apparatus for efficiently performing routing in a wireless sensor network having a tree-hierarchical structure, the method and apparatus reducing the number of hops required for transmitting data. According to the method and apparatus, a node is determined as a proximal node from among nodes within range of a wireless signal of a transmission node, wherein the node is a node having the smallest difference from among differences between each of address values of the nodes within the range and an address value of a target node, and data is directly transmitted from the transmission node to the proximal node.

Provided are a coordinator, a gateway, and a transmission method for applying IPv6 in a wireless sensor network (WSN). Dual addressing of a link local address using a short address used in the WSN and a global unicast address using an extended unique identifier (EUI) of a node makes it possible to support mobility of the WSN and communicate data with an external network.

A method of forming a metal thin film can reduce leakage current while improving electric properties by improving step coverage of a device. The method of forming a metal thin film includes supplying a metal precursor including chlorine, purging byproducts produced after the supplying of the metal precursor by injecting a purge gas, supplying a reactant to allow the reactant and the metal precursor to react with each other to form a thin film layer, and purging the byproducts produced after the reaction by injecting a purge gas, wherein before the supplying of the metal precursor, the method further includes supplying a reactant to be adsorbed on a treated product.

Methods of fabricating a semiconductor device include forming a deposited film on a semiconductor substrate in a process chamber by repeatedly forming unit layers on the semiconductor substrate. The unit layer is formed by forming a preliminary unit layer on the semiconductor substrate by supplying a process material including a precursor material and film-control material into the process chamber, purging the process chamber, forming a unit layer from the preliminary unit layer, and again purging the process chamber. The precursor material includes a central atom and a ligand bonded to the central atom, and the film-control material includes a hydride of the ligand.

In a method of forming a layer, a precursor including a metal and a ligand coordinating to the metal is stabilized by contacting the precursor with an electron donating compound to provide a stabilized precursor into a substrate. A reactant is introduced into the substrate to bind to the metal in the stabilized precursor. The precursor stabilized by the electron donating compound has an improved thermal stability and thus the precursor is not dissociated at a high temperature atmosphere, and the layer having a uniform thickness is formed on the substrate.

To form a dielectric layer, an organometallic precursor is adsorbed on a substrate loaded into a process chamber. The organometallic precursor includes a central metal and ligands bound to the central metal. An inactive oxidant is provided onto the substrate. The inactive oxidant is reactive with the organometallic precursor. An active oxidant is also provided onto the substrate. The active oxidant has a higher reactivity than that of the inactive oxidant.
