发明名称 MEMS SCANNER HAVING COIL AND MANUFACTURING METHOD OF COIL FOR MEMS SCANNER
摘要 The present disclosure may provide a MEMS scanner including a mirror configured to reflect light, a gimbal connected to the mirror to rotatably support the mirror, and a winding portion provided at the mirror or the gimbal to generate an electromagnetic force in interaction with a magnetic field formed in the vicinity when a current flows therethrough so as to adjust a rotational angle of the mirror, wherein the winding portion includes a silicon layer, a coil layer deposited on the silicon layer to generate physical deformation due to a current flowing therethrough, and a plurality of hollow holes formed on the coil layer to provide elasticity so as to reduce an amount of impact due to the physical deformation, and increase the dissipation area of heat generated.
