  • Patent number: 8303197
    Abstract: In an apparatus for performing a substrate developing process, a first washing tank and a second washing tank are disposed on both sides of a substrate support section for supporting the substrate opposite to each other to wash a developing nozzle. The developing nozzle moves in a horizontal direction from the first washing tank toward the second washing tank and supplies a developing solution onto the substrate in the meantime. After supplying the developing solution, the developing nozzle is received in the second washing tank, and the developing solution adhered to the developing nozzle is removed by a washing solution in the second washing tank.

  • Patent number: 8084351
    Abstract: A method for fabricating a contact of a semiconductor device includes the steps of forming a dielectric layer having a contact hole on a semiconductor substrate, forming an out-gassing barrier layer comprising a poly-silicon layer to cover at least inner walls of the contact hole in order to prevent undesired out-gassing from the dielectric layer, and depositing an aluminum layer on the out-gassing barrier layer. The contact structure of the semiconductor device includes the aluminum layer filled in the contact layer formed on the semiconductor substrate, and the out-gassing barrier layer formed under the aluminum layer to prevent out-gassing from the dielectric layer. A fine contact can be formed along with the aluminum layer, thereby realizing the contact structure of a lower contact resistance. As a result, it is possible to realize stabilization of an overall contact resistance of the semiconductor device.
