Method for manufacturing e.g. permanently magnetized polymer magnet, to be utilized in e.g. encoder for detecting linear layer alteration, involves radiating resist in recess so that resist is cured, and removing tool from carrier

摘要

The method involves generating a permanent magnetic layer (120) from a permanent magnetic negative resist, on a part of a surface of a carrier. A given portion of the magnetic layer is selectively radiated (130) with a determined radiation to change the solubility of the resist in the portion. A molding tool is placed on the carrier, and a recess is partially filled with the resist that is made of polymer. The resist is radiated in the recess with a determined radiation so that the resist is cured to a permanent magnetic structure in the recess, and the tool is removed from the carrier. The permanent magnetic negative resist is selected from UV light sensitive photoresist, an X-ray resist, an electron resist or an ion resist. An independent claim is also included for a permanent magnet comprising a permanent magnetic structure.
