CYLINDRICAL MICRO PATTERN COIL AND CYLINDRICAL MICRO MOTOR USING SAME

Document Type and Number:

WIPO Patent Application WO/2012/014866

Kind Code:

A1

Abstract:

Disclosed is a cylindrical micro pattern coil having ensured productivity, in which a semiconductor is filled in an ultrafine pattern coil groove formed in a curved surface of a cylindrical substrate. An ultrafine pattern coil groove is formed, by means of a nano-imprint method, in a cylindrical substrate comprising a resin material. Ink in which particulate metal is dispersed is burned in the inner side of the pattern coil groove to form a metal film. Then, copper plating is performed using the metal film as a seed layer, to thereby form a pattern coil.
