A high performance TMR element is fabricated by inserting an oxygen surfactant layer between a pinned layer and AlOx tunnel barrier layer in a bottom spin valve configuration. Islands and voids extend across the carrier to reduce the ridigity of the carrier. Further, the input stage is configured to balance the source signal using behavior parameters and generate a balanced source signal. In recovering the flash, the apparatus does not adversely affect the speed or quality of production of the final shaped or laminated product. Since adjacent via holes are arranged in a staggered arrangement with each other, the distance between the adjacent via holes is larger than the spiral pitch of the antenna line, allowing the adjacent portions to be closer together than a conventional chip antenna, thereby allowing the resonance frequency to be reduced.
