Title: Plasma etching method
Inventor: NAWATA MAKOTO
IPC: C23F4/00
Filed: 1993-12-28
Abstract: PURPOSE:To prevent fluctuation in a residual oxide film on a substrate surface by suppressing a decrease in the etching speed of silicon and oxide film after cleaning and by performing seasoning with plasma such as Cl2 gas after cleaning thereby decreasing the influence of residue inside a treatment chamber. CONSTITUTION:Microwave oscillated from a magnetron 1 propagates through a wave guide 2 and is introduced to a treatment chamber 4 through a microwave introducing window 3. A cleaning gas (SF6), seasoning gas (Cl2 gas) and etching gas (C2 gas) supplied from an etching gas supply apparatus 8 are turned into plasma. Cleaning of the treatment chamber 4 is performed by SF6 gas plasma. Seasoning of the treatment chamber 4 is performed by Cl2 gas plasma. A wafer 10 placed on a mounting electrode 9 is etched by Cl2 gas. By doing this, the influence of the residual fluorine after cleaning is suppressed, and a decrease in the etching rate of silicon and oxide film can be prevented.

IPC: A61B5/055
Filed: 1992-12-17
Abstract: PURPOSE:To reduce the effect of the induced electromotive force induced from the potential difference of the primary electrocardiographic complex and the bloodstream in the static magnetic field by optimizing the layout of electrocardiographic complex detecting electrodes. CONSTITUTION:The effect of the induced electromotive force is reduced when the layout is optimized for electrodes 1, 2, 3 consisting of the electrocardiographic complex detecting electrode 1 (plus), the electrocardiographic complex detecting electrode 2 (minus), and the electrocardiographic complex detecting electrode 3 (earth). The induced electromotive force is generated in the direction perpendicular to the direction of the magnetic flux of the static magnetic field and the bloodstream direction according to the Fleming's right hand rule. The direction from the electrocardiographic complex detecting electrode 1 to the electrocardiographic complex detecting electrode 2 is made the same as the direction of the magnetic flux of the static magnetic field.
