The structure consists of at least one glass-ceramic sheet (1) with holes (3) being filled with a conductive material (4) having a TCE slightly higher than that of the glass-ceramics and having undergone liquid phase sintering at the crystallization temperature of the glass-ceramic material (2) with the solid phase comprising conductive particles (5) and the liquid phase comprising at least a glass (6). The method comprises the steps of providing a green sheet comprising an organic vehicle and particles of a crystallizable first glass and having via holes, filling the via holes with a paste comprising an organic vehicle, and an inorganic material comprising conductive particles and at least a second glass being low viscous at the sintering temperature, firing the then present structure in a reducing, neutral or slightly oxidizing atmosphere with the temperature being slowly raised to said sintering temperature and slowly cooling the structure.
