Abstract

PURPOSE:To form a sheet coil having a high electric efficiency, by applying ion beams in a plane-vortex pattern onto a conductive film. CONSTITUTION:Pattern coil 2 and 3 are formed by applying Ar<+> ion beams in a vortex pattern onto both surfaces of a thin film 1 of an organic compound by using a focused ion beam irradiation apparatus. In this example, the coils 2 and 3 on both front and back surfaces are provided in correspondence to each other so that the magnetic centers thereof coincide with each other, and the respective inside ends 5 and 6 of the coils are made continuous electroconductively and connected in series to each other through a through hole 4 formed in an insulative portion of the thin film 1. According to this constitution, Ar<+> intrudes into the insulative thin film 1 of the organic compound, and thereby the electroconductive coil portions 2 and 3 are formed as shown in the sectional view of the coils.

Become. In addition, although sheet coils formed by photoetching are designed to improve the space factor by reducing the spacing between the coil conductors to t-30 to 100 μm, the width of the etching is It can only be made as small as several times the thickness of the copper foil, which limits the precision of the coil pattern.Furthermore, due to its structure, an insulating substrate is required.
This further reduces the conductor space factor in the coil cross section.
