METHOD FOR MANUFACTURING A MEMBRANE AND OBJECT PROVIDED WITH SUCH A MEMBRANE
First Claim
1. A method for manufacturing a membrane of a depositable material at an opening of an object, which comprisesplacing the opening with a defined rim against a backing surface coated with a layer repellent to the depositable material;
- depositing of the depositable material on the object and the backing surface to form an element; and
separation of the element from the backing surface leaving a membrane integral with the element.

Abstract
The present invention relates to a method for manufacturing a membrane or wall (3) of a material, which is capable of vapour/vacuum deposition, over an opening of an object (2). The method includes: placing the opening with a defined rim against a backing surface (4) coated with a layer (5) repellent to the depositable material; depositing of the depositable material on the object (2) and the backing surface (4) to form an element; separation of the element from the hacking surface (4) leaving a membrane (3) integral with the element. The invention also relates to such an object provided with a membrane (3), and particularly an ultrasonic transducer (11) provided with a front membrane (3).

- 7. An object comprising at least one opening and a membrane of a depositable material arranged to cover said at least one, the membrane being attached to a defined rim of the opening and said membrane being integral at said defined rim with a continuous element of the depositable material deposited on and covering the object, so as to form a chamber with the deposited material.
