A method of providing a semi-manufactured stamper, the method comprising the steps of: a) selecting a disc-shaped member (100) having a flat first surface (105; 106), and a second surface (112) forming a back surface of the semi-manufactured stamper; the first surface of the disc-shaped member (100) being structurable and substantially unstructured; b) applying a layer (120; 240) sensitive to irradiation on said first surface (105) such that an unexposed and exposable semi-manufactured stamper is provided; c) enclosing (S50) the unexposed semi-manufactured stamper in a protective package such that the sensitive film is maintained substantially unexposed; and d) treating (S30) the semi-manufactured stamper, before performing step c), such that its geometry makes it suitable for mounting in an injection moulding machine; said treatment including treating said second surface (112) of the semi-manufactured stamper such that a mean surface deviation value (Rz) below 2 micrometer is obtained. |
