Abstract

Ein Abgleichwiderstand wird hergestellt durch Abscheiden einer Widerstandsschicht (3) auf einem Substrat (1), einer Passivierungsschicht (5) mit Fenstern (4) und einer Kontaktschicht (6), die mit der Widerstandsschicht (3) durch die Fenster (4) in Kontakt steht. Ein Abgleich erfolgt durch Unterbrechen der Kontaktschicht (6) an Engstellen (7). Anwendung für die Herstellung von Hochdrucksensoren.

Figure 00000001
A trimming resistor is produced by depositing a resistance layer (3) on a substrate (1), a passivation layer (5) with windows (4) and a contact layer (6) which is in contact with the resistance layer (3) through the windows (4) stands. A comparison is made by interrupting the contact layer (6) at narrow points (7). Application for the production of high pressure sensors.
