Pressure difference sensor for determining a pressure measurement signal

A pressure difference sensor for determining a pressure measurement signal, comprising:

• a pressure difference measuring cell including a semiconductor material, wherein the pressure difference measuring cell is suppliable with first and second pressures and, with the use of an electrical transducer element, outputs the pressure measurement signal as a function of a difference between the first and second pressures;
• a first stiffening element joined with the pressure difference measuring cell by a first joining layer and having a first duct via which the first pressure is suppliable to the pressure difference measuring cell;
• and
• a second stiffening element joined with the pressure difference measuring cell by a second joining layer and having a second duct via which the second pressure is suppliable to the pressure difference measuring cell;
• wherein the first and/or the second joining layer include(s) an electrically conductive material and the first and/or second joining layer provide(s) a mechanical connection of the pressure difference measuring cell with the first and second stiffening elements and also implement an electrical functionality.
