Title: Magnetron sputtering device
Inventor: KIUCHI KATSUMI
IPC: C23C14/36
Filed: 1985-04-17
Abstract: PURPOSE:To prevent the sticking of the deposited foreign matter of reactant scattering from a non-sputtering region during film formation onto a film forming surface by attaching a substrate onto a substrate support via a target facing the same and an insulator and providing further a bias power voltage source. CONSTITUTION:The substrate 6 is attached onto the substrate support 7 in the state of insulating the substrate via the insulator 41. The bias voltage source 42 which impresses the bias voltage for preventing the scattering foreign matter is provided to the substrate 6. The substrate 6 is rotated and a bias voltage of a negative polarity is impressed to the substrate 6 from the voltage source 42. The reactant deposited to the non-sputtering region on the target 3 surface is partially stripped and is scattered in the form of the coarse particles electrified to the negative polarity toward the substrate 6 side. The scattering particles are expelled so as to be pushed back to the target 3 side by the electrical reaction acting between the particles and the substrate 6 maintained at the negative potential. The sticking of the scattering coarse particles onto the substrate 6 surface is thus prevented and the deposition and formation of the thin film having good quality without defects are made possible.

Filed: 1993-04-12
Abstract: PURPOSE:To provide the agent containing lactic acid alone or a combination of the lactic acid with at least one of phosphoric acid and acetic acid and capable of controlling the red rod fungi in a short time without damaging the sea laver itself. CONSTITUTION:A sea laver red rod fungus control agent comprises lactic acid as an active ingredient, preferably, >=0.4wt.% solution of lactic acid in seawater. The agent preferably comprises at least one acid selected from malic acid and acetic acid in addition to the lactic acid, especially, >=0.1wt.% of malic acid and <=0.4wt.% of acetic acid in addition to >=0.10wt.% of lactic acid.
