    摘要: A plurality of bar-like magnets are arranged in a vacuum chamber at an equal space interval to form a plurality of strong magnetic fields in a stripe-pattern form and the magnets are moved reciprocally in the direction of arrangement of the magnetic fields while changing gradually the stop points of the magnets over a work to be processed by etching or sputtering in a step-like manner so that the integral effect of each magnetic field acting on the work is uniform over the entire region of the work.

    摘要: A method of forming an insulating film of high breakdown voltage on a polycrystalline substance layer which comprises the steps of preparing the polycrystalline substance layer; selectively removing the polycrystalline substance layer; heat-treating for the first time that portion of the polycrystalline substance layer which is left after said selective removal in an oxidizing atmosphere to provide an oxide layer; removing the whole of said oxide layer; and heat-treating for the second time in an oxidizing atmosphere the polycrystalline substance layer which is now exposed due to removal of said oxide layer, thereby forming a second oxide layer acting as an insulating film on said exposed surface.
