Thin film meander inductors having 10-6m range coil spacing were fabricated successfully. The inductance measured with microstrip line increased with increasing the coil spacing due to the dielectric coupling between the meander lines. Maximum value of the applicable current density is examined and it is clarified that the magnetic thin films are requested to provide high saturation magnetization in order to remain in the under saturated region in case of high current density applications. These results give a basis for developing thin film micro inductors and transformers.
