Method for the manufacture of a membrane-containing microstructure
First Claim
1. A method for the manufacture of a microstructure having a top face and a bottom face, at least one hole therein extending from the top face to the bottom face, and a polymer membrane which extends over a bottom opening of said hole, which method comprises the steps of:
- a) providing a substrate body (2;
21) having said top and bottom faces,b) forming at most part of said at least one hole (9;
24) in the top face of the substrate body,c) providing a membrane support layer (13;
25)(i) in said part of said at least one hole formed in step (b) and completing said at least one hole from the bottom face of said substrate body, or(ii) on the bottom face of said substrate body,d) depositing a layer of polymer material onto the bottom face of said substrate body (2;
21) against said membrane support layer (13;
25) to form a polymer membrane (15;
26),e) completing the formation of the at least one hole (9;
24) if step (c) is according to alternative (ii), andf) selectively removing said membrane support layer (13;
25) to bare said polymer membrane (15;
26) over the bottom opening of the at least one hole.

Abstract
A method for the manufacture of a microstructure having a top face and a bottom face, at least one hole or cavity therein extending from the top face to the bottom face, and a polymer membrane which extends over a bottom opening of said hole or cavity, which method comprises the steps of: providing a substrate body having said top and bottom faces, optionally forming at least part of said at least one hole or cavity in the substrate body, providing a membrane support at the bottom face opening of said at least one hole or cavity, depositing a layer of polymer material onto the bottom face of said substrate body against said membrane support, if required, completing the formation of the at least one hole or cavity, and, if not done in this step, selectively removing said membrane support to bare said polymer membrane over the bottom opening of the at least one hole or cavity.
