Abstract
The present invention discloses a mask pattern transferring device and a method of preparing a mask pattern transferring device. The mask pattern transferring device comprises: a magnetization head disposed on a magnetization head carrying device, for magnetizing composite powders each comprising a core of ferromagnetic metal and an outer resin film; a rotary roller formed of a non-ferromagnetic material, for adsorbing the composite powders magnetized by the magnetization head; a demagnetization head disposed at a downstream of the magnetization head in the rotating direction of the rotary roller, for demagnetizing the magnetized composite powders adsorbed by the rotary roller; and a collecting container, the outer edge of which is tangent with one side of the rotary roller, and which is disposed at the downstream of the magnetization head along the periphery of the rotary roller to collect the demagnetized composite powders.
