The micromachining difficulties from the coexistence of 3-D MEMS devices and deep grooves on chip are overcome successfully. Then two fibers and permalloy piece are assembled onto the wafer together with the microstructures finishing the prototype of the new type MEMS VOA. Third, the inductance, resistance and Q value of the microfabricated solenoids are measured in the frequency range of 1-40 MHz.
