Abstract:
1. A mask pattern transferring device, comprising: a magnetization head disposed on a magnetization head carrying device, for magnetizing composite powder, each particle of the composite powder comprising a core of ferromagnetic metal and an outer resin film; a rotary roller formed of a non-ferromagnetic material, for adsorbing the composite powder magnetized by the magnetization head; a demagnetization head disposed downstream the magnetization head in a rotating direction of the rotary roller, for demagnetizing the magnetized composite powder adsorbed by the rotary roller; and a collecting container, an outer edge of which is tangent with the rotary roller, and which is disposed downstream the magnetization head along a periphery of the rotary roller to collect the demagnetized composite powder, wherein the mask pattern transferring device further comprises a spray device disposed below the collecting container, for spraying a material, which improves the capability of the magnetized composite powder to be adsorbed onto the rotary roller, onto a part of the rotary roller between a lower outer edge of the collecting container and the magnetization head.
