Abstract
A method for producing an electronic component includes providing a piezoelectric main body, which is provided with electrodes. A first electric polarization field having a first polarity direction is applied to the piezoelectric main body between the two electrodes and then a second electric polarization field is applied in a second polarity direction, opposite to the first polarity direction, to the piezoelectric main body between the electrodes. The absolute value of the second electric polarization field differs from that of the first electric polarization field.

A method for producing an electronic component, the method comprising:
- providing a piezoelectric main body that includes a plurality of electrodes;
- applying a first electric polarization field having a first polarity direction to the piezoelectric main body between the electrodes, wherein, after applying the first electric polarization field, a deflection of the piezoelectric main body as a function of the applied electric polarization field follows a hysteresis curve that determines an electric coercive field strength;
- after applying the first electric polarization field, applying a second electric polarization field in a second polarity direction opposite to the first polarity direction to the piezoelectric main body between the electrodes, wherein the absolute value of the second electric polarization field differs from the absolute value of the first electric polarization field, and wherein the absolute value of the second electric polarization field is less than the absolute value of the electric coercive field strength;
- and
- completing the electronic component.
