In order to push magnetic random access memory (MRAM) into the GHz operation regime, coplanar wave guides must be used for applying the magnetic field pulses. We have developed a complex 3D sample structure consisting of a base stack of three different microstructured field pulse lines isolated against each other which form the carrier of the magnetic element. In contrast to using inorganic isolation layers we improved the sample processing using the organic photoresist benzocyclobuthene BCB (Dow Chemical, cyclotheneTM 4026), which provides fast usage, high planarization, good isolation and flexibility to adjust the isolation layers to the sample design.
