Method for forming a sensor circuit

A method for forming a sensor circuit, the method comprising:

• forming a plurality of magnetoresistive structures having a first predefined reference magnetization direction in a first common area of a common semiconductor substrate, wherein the forming the plurality of magnetoresistive structures having the first predefined reference magnetization direction comprises laser treatment of the first common area during a first time interval;
• forming a plurality of magnetoresistive structures having a second predefined reference magnetization direction in a second common area of the common semiconductor substrate, wherein the forming the plurality of magnetoresistive structures having the second predefined reference magnetization direction comprises laser treatment of the second common area during a subsequent second time interval;
• and
• forming electrically conductive structures electrically coupling the magnetoresistive structures having the first predefined reference magnetization direction to the magnetoresistive structures having the second predefined reference magnetization direction to form a plurality of half-bridge sensor circuits, wherein each half-bridge sensor circuit comprises a magnetoresistive structure having the first predefined reference magnetization direction electrically coupled to a second magnetoresistive structure having the second predefined reference magnetization direction.
