Claim 12:
13. A method for a production of a microelectronics device, comprising:
providing a microelectronics device, including:
at least one bearer substrate, and
at least one layered piezo stack situated on the bearer substrate, the piezo stack having at least one piezo element and at least one electrode, and
at least one contact opening situated on the at least one electrode;

wherein:
the method further comprises forming at least one diffusion blocking element on the at least one electrode at least partly at a distance from the piezo element; and/or
the at least one contact opening forms a contact surface that is at most as large as one one-thousandth of a surface of the at least one piezo element; and/or
a length of an electrical path from the at least one contact opening to the at least one piezo element corresponds to at least twice a circumference of the at least one contact opening.
