Patent ID: 8551352

Claim:
Method for producing a device with a membrane used to encapsulate a fluid contained in a cavity, wherein: two substrates are provided; a membrane is placed on one and/or on the other of the substrates; one or more walls are formed, helping to laterally define the cavity, in which said walls are located on or in one of the substrates and/or on or in the other of the substrates, and said cavity is intended to contain the fluid, the two substrates are assembled together by superimposing one on the other so as to complete the cavity, in which the or each membrane also helps to define the cavity, the fluid is encapsulated in the cavity between the substrates, and the or each membrane is soaked by the fluid, at least a portion of one of the substrates and/or the other of the substrates is removed insofar as one and/or the other of the substrates are equipped with a membrane, in order to release the membrane at least in the central portion thereof, and the membrane is at least partially supported by the fluid as it is released.
