摘要： The process consists in submitting the surface layer of an electrolytically oxidizable metal to the action of an electrical field with a higher field intensity than the breakdown intensity during an anodizing step.
Under such conditions, extremely intense energy exchanges occur in a region confined on the surface of the immersed article; the resulting physical and chemical processes cause, among others, any impurities to be nearly immediately removed, and a useful surface conditioning layer for subsequent processes to be produced.
The process is particularly useful for high-speed treatment of bands of light alloy or other oxidizable materials.

摘要： A method of low-damage, anisotropic etching and cleaning of substrates including mounting the substrate upon a mechanical suport located within the positive column of a plasma discharge generated by either an ac or dc plasma reactor. The mechanical support is independent of the plasma reactor generating apparatus and capable of being electrically biased. The substrate is subjected to the positive column, or electrically neutral portion, of a plasma of low-energy electrons and a species reactive with the substrate. An additional structure capable of being electrically biased can be placed within the plasma to control further the extraction or retardation of particles from the plasma.

摘要： This invention relates to a method for the electrolytic removal of plastic mold flash or bleed from the metal surfaces of semiconductor devices and similar electronic components by immersing such components in a water based solution of one or more organic solvents, conducting salts and a wetting agent and whereby the components to be cleaned are connected to the negative pole of a source of direct current, of which the positive pole is connected to an anode in the same solution and whereby during passing a current through the solution the pH of the liquid film directly adjecent to the cathodic metallic surface is raised to a value at which the solvent causes a softening action on the plastic mold flash or bleed, which is sufficient to enable the hydrogen gas, generated simultaneously on the cathode to remove the plastic mold flash or bleed from the metal surface.
The invention relates also to a composition of a water based solution to be used with this method.
