Abstract
Die Erfindung betrifft ein Isolatorschichtsystem (10) für einen Sensor (1), insbesondere für einen in Dünn- oder Dickschichttechnik hergestellten Druck- oder Kraftsensor, mit einem Schichtsystem (10), das eine erste Schicht und eine zweite Schicht aufweist, wobei die erste Schicht ein erstes Element aufweist und die zweite Schicht ein zweites Element aufweist, das von dem ersten Element verschieden ist, dadurch gekennzeichnet, dass der Übergang zwischen der ersten Schicht und der zweiten Schicht durch einen Übergangsbereich (14, 18, 22, 26) gebildet ist, dass die Konzentration des ersten Elements im Übergangsbereich (14, 18, 22, 26) ausgehend von einem der ersten Schicht zugewandten Ende des Übergangsbereichs (14, 18, 22, 26) in Richtung auf ein der zweiten Schicht zugewandtes Ende des Übergangsbereichs (14, 18, 22, 26) mindestens abschnittsweise kontinuierlich zunimmt und/oder abnimmt, und/oder dass die Konzentration des zweiten Elements im Übergangsbereich (14, 18, 22, 26) ausgehend von einem der zweiten Schicht zugewandten Ende des Übergangsbereichs (14, 18, 22, 26) in Richtung auf ein der ersten Schicht zugewandtes Ende des Übergangsbereichs (14, 18, 22, 26) mindestens abschnittsweise kontinuierlich zunimmt und/oder abnimmt, sowie einen Sensor (1) mit einem solchen Isolatorschichtsystem (10).
