Title: Ion beam etching system
Inventor: YOSHIKAWA TOSHIAKI
IPC: H01L21/302
Filed: 1986-08-25
Abstract: PURPOSE:To inhibit the diffusion of ion beams projected from an ion source, and to utilize ion beams effectively by installing a cylindrical compensating electrode between the ion source and a material to be etched. CONSTITUTION:A compensating electrode 14 for suppressing the diffusion of an ion current and compensating the ion current in the direction of focusing is mounted into an etching chamber 9 between an ion source 2 and a material to be etched 10. The compensating electrode 14 is constituted of a continuous wall body consisting of a non-porous material such as a metallic band material. Positive ions generated by the ion source 2 are accelerated toward the material to be etched 10 by an ion accelerating electrode 8. The accelerated positive ion current is reflected in the central direction by the compensating electrode 14 to which positive potential is applied by a power supply 15, and projected to the material to be etched 10 without being diffused. Since the compensating electrode 14 takes a conical shape, it compensates the ion current in the direction that the ion current is focussed effectively toward the material to be etched 10.

Title: Electrode for anticorrosion test
Inventor: MAEJIMA SHIGETO
IPC: G01N27/30
Filed: 1990-07-23
Abstract: PURPOSE:To enable measurement of a polarization resistance distribution of the surface of an object to be measured by measuring a natural potential between an opposed pole and the object to be measured with the potential of a collation electrode as reference through a packing. CONSTITUTION:An electrode 10 for anticorrosion tests is set on the surface of a metal material 5 as object to be measured and connected to a potentiostat 7. Under such a condition, a natural potential E1 is measured between the material 5 as working pole and an opposed pole 3 housed in a body container 2 with the potential of a collation electrode 2 as reference. Then, a polarization is made by a fixed potential V1 positive and negative with the natural potential E1 thus obtained as reference and currents I11 and I12 given are measured. Subsequently, a polarization resistance value R1 is calculated by a specified formula. A very small part is enough for measurement to allow the measurement of an anticorrosive distribution within the same material. It is also necessary to provide a packing 6 when a tip of a through hole of the body container 2 is brought into contact with the material 5. The packing plays a role of a buffer material while it serves to keep an electrolyte 11 liquidtight to prevent leakage thereof to outside.
