Abstract (en)
[origin: WO2014086611A1] The invention relates to a method for producing an electronic component (100). The method comprises the providing of a piezoelectric base body (1) having electrodes (2), the creating of a first electrical polarization field (E1) having a first polarity direction on the piezoelectric base body (1) between the two electrodes (2), the creating of a second electrical polarization field (E2) after the creating of the first electrical polarization field (E1), in a second polarity direction opposite to the first polarity direction, on the piezoelectric base body (1) between the electrodes (2). The value of the second electrical polarization field (E2) differs from that of the first electrical polarization field (E1).
