Zusammenfassung:	Methods for improving adhesion between various materials utilized in the fabrication of integrated circuits. A first method relates to improving adhesion between a silicon nitride layer and a silicon dioxide layer. The method includes treating a surface of the silicon dioxide layer with a nitrogen plasma in a reactive ion etching process prior to depositing the silicon nitride film on the surface of the silicon dioxide layer. A second method relates to improving adhesion between a silicon nitride layer and a polyimide layer. The method includes the step of treating a surface of the silicon nitride layer with a oxygen/argon plasma in a reactive ion etching process prior to depositing the polyimide layer film on the surface of the silicon nitride layer. A third method relates to improving adhesion between a photoresist layer and a metal. The method includes the step of treating a surface of the photoresist layer with a oxygen/argon plasma in a reactive ion etching process prior to depositing the metal on the surface of the photoresist layer.
