    Abstract: Disclosed herein is a plasma processing apparatus, which generates plasma within a vacuum chamber to process semiconductor substrates using the plasma. The apparatus comprises a substrate mounting table, an outer lifting bar, and a baffle. The outer lifting bar comprises a driving shaft, and a substrate supporting member coupled perpendicular to an upper end of the driving shaft. The baffle comprises a baffle plate coupled to the upper end of the driving shaft, and a shielding portion coupled to a lower surface of the baffle plate. The substrate supporting member is a foldable substrate supporting member. The baffle and the substrate supporting member are driven up and down at the same time by the driving shaft. As a result, it is possible to protect the substrate supporting member from plasma, and to prevent interference between the baffle and the outer lifting bar during operation of the plasma processing apparatus.

    Abstract: A DRAM cell capacitor having a high capacitance is obtained by forming a lower capacitor electrode of TiN and a roughened tungsten film on the TiN layer. A high dielectric constant film, such as tantalum pentaoxide, is then provided on the tungsten film and an upper capacitor electrode is deposited on the dielectric film. A method of forming the roughened tungsten film includes the step of depositing tungsten on the TiN layer at a temperature in the range of 200-650° C.

    Abstract: A capacitor structure of a semiconductor device which includes a semiconductor substrate, a first metal layer formed on the substrate, and a second metal layer formed on the first metal layer. The first metal layer has a nitridation-treated film along its outer surface. A tungsten film having a rugged surface is formed on the entire outer surfaces of the first and second metal layers. Because of the nitridation-treated film along the first layer, the tungsten film will be uniformly distributed along the first and second metals. A thin dielectric film is then formed on the surface of the tungsten, followed by a third metal layer formed on the dielectric film.
