Transition from a thin film to a thick film in electrically conducting devices

A method for producing a device for conducting an electrical current, the method comprising the steps of:

• providing an electrically insulating substrate (3) comprising a first side (3a), wherein a first electrical conductor (4) is arranged on the substrate (3) and comprises a first portion (40) protruding from the first side (3a) of the substrate (3),
• providing an edge region (400) of the first portion (40) of the first electrical conductor (4) such that said edge region (400) comprises a beveled or rounded cross-sectional contour in a cross-sectional plane extending orthogonal to the first side (3a) of the substrate (3), and
• sputtering a metallic layer (2) onto the first side (3a) of the substrate (3), so that said metallic layer (2) comprises a transition region (20) overlapping at least said edge region (400) of said first portion (40) of the at least one conductor (4).
