Patent ID: 7805820

Claim:
A method for producing a multi-layer component, which comprises: A) providing a multi-layer system with an uppermost layer formed by a first dielectric layer; B) applying a Si-containing second dielectric layer directly onto and in contact with the first dielectric layer and a photoresist layer onto the second dielectric layer; C) structuring the photoresist layer to form a first mask; D) structuring the second dielectric layer with aid of the first mask, whereby structures of the second dielectric layer together with structures of the first mask located there above form a second mask; E) structuring the first dielectric layer with aid of the second mask; F) removing the photoresist layer; G) permitting the second dielectric layer of the second mask to remain on the multi-layer system; and H) utilizing the second dielectric layer of the second mask as a functional layer of the multi-layer system.
