Claim 0:
1. A method of fabricating a device including a membrane overhanging a useful cavity, the method comprising:
providing a generic structure including a superficial layer extending in a main plane and arranged on a first side of a carrier substrate, the carrier substrate including elementary cavities opening under the superficial layer and partitions delimiting each elementary cavity, the partition having upper surfaces that form all or some of the first side of the carrier substrate;
defining a group of adjacent elementary cavities, such that a contour of the group of adjacent elementary cavities corresponds, in the main plane, to a contour of the useful cavity; and
removing the partitions located inside the contour of the group of adjacent elementary cavities, to form the useful cavity, and to free up the superficial layer arranged above the useful cavity and making up the membrane.
