Abstract
A metallic thin film 15 is formed on a mold 11 having protrusions 12 complementary in shape to a conductor pattern to be formed; a substrate 17 having a transfer layer 16 of adherent (or adhesive) material applied to one side surface thereof is provided; and the transfer layer 16 side of the substrate is brought into intimate contact with the metallic thin film 15 laid over the protrusions 12, followed by pulling the transfer layer apart from the mold so as to transfer the metallic thin film 15 covering the protrusions 12 onto the transfer layer 16 to thereby form the conductor pattern 18 on the transfer layer 16. The metal film may include cooper and a weak adherence layer 13 which may be gold.
Claims4
An electrical connecting element comprising:
- a transfer layer made of either one of adherent material and adhesive material;
- a conductor pattern adherently attached to said transfer layer by means of adherent power of the transfer layer itself;
- wherein said conductor pattern comprises a plurality of conductor lines arranged in an array;
- and including two of said transfer layer each having said conductor pattern adherently attached thereto;
- and wherein
- one halves, as viewed lengthwise of the conductor lines, of the conductor patterns of the two transfer layers are positioned in opposing contact with each other such that those portions of said two transfer layers between said conductor patterns are adherently attached together;
- and including spacers attached to the surfaces of the other halves of the conductor patterns of the two transfer layers on the side opposite from the respective conductor patterns;
- and
- those portions of said conductor patterns lying on the surfaces of said two transfer layers opposite from the side on which the respective spacers are attached constitute connecting portions, respectively.
