1. A method for manufacturing a carrier (40) for enabling accurate positioning of an optical element (45;

  • 61) in relation to a optical semiconductor element (41) to be connected to the carrier (40), the method comprising the steps of;

    providing (201) an electrically conductive multi-layer carrier base sheet (10) having an upper carrier layer (13), a lower carrier layer (14), and an intermediate carrier layer (12) between said upper and lower carrier layers;

    forming (206, 207) an upper conductor structure (22) in said upper and intermediate carrier layers (13, 12); and

    providing (208, 209) a patterned insulative spacer layer (26) on an upper carrier layer side of said carrier base sheet (10),wherein;

    said insulative spacer layer (26) is patterned such that at least one cavity (27) is formed in which said optical semiconductor element (41) is connectable to said upper conductor structure (22), a depth of said cavity (27) being greater than a height of the optical semiconductor element (41) when connected to said carrier (10); and

    said cavity (27) is formed to define a location of said optical element (45;

    61) in relation to said optical semiconductor element (41).
