Patent ID: 7037844

Claim:
A method for manufacturing a housing for a chip having a micromechanical structure, comprising the following steps: (a) providing a first basis which comprises a photolithographically structurable layer on at least a partial region of a main face; (b) photolithographically structuring the first photolithographically structurable layer to obtain a cover for the micromechanical structure; (c) providing a chip comprising the micromechanical structure, which is arranged at a main face of the chip between the first contact elements; (d) applying a second photolithographically structurable layer on at least a partial region of the main face of the chip; (e) photolithographically structuring the second photolithographically structurable layer for generating a recess surrounded by a wall in the photolithographically structurable layer in the region of the micromechanical structure and for exposing the first contact elements; (f) merging the first basis and the chip in a way so that the micromechanical structure and the cover are facing each other and are aligned with each other, so that the recess is closed by the cover, whereby an on-chip cavity is obtained; (g) removing the first basis in order to obtain a chip comprising an on-chip cavity; (h) merging a second basis and the chip comprising the on-chip cavity in such a way that the first contact elements are connected to the second basis via a conductive structure; and (i) removing the second basis for exposing the conductive structure.
