摘要:
A semiconductor module having an integrated structure is manufactured by mounting a semiconductor chip on the side of a surface of a cooling plate via an insulating material, and by molding the semiconductor chip and the cooling plate by a resin-molded member. This method includes the steps of: (a) forming a sprayed insulating film as the insulating material on a surface of the cooling plate; (b) forming a sprayed conductive film on a face of the sprayed insulating film opposite to a face where the cooling plate is provided; (c) checking whether the sprayed conductive film is insulated from the cooling plate by using the sprayed conductive film and the cooling plate as electrodes and applying voltage therebetween; and (d) mounting the semiconductor chip on the upper side of the sprayed conductive film when the sprayed conductive film is insulated, and then resin-molding the semiconductor chip and the cooling plate.

The invention relates to a method for manufacturing a hot-dip plated metal strip comprising the steps of: introducing a metal strip into a molten metal bath of plating metal to adhere the molten metal onto the surface of the metal strip; taking out the metal strip, after turning the running direction of the metal strip, from the molten metal bath without applying external force from outside the surface of the metal strip; adjusting the plating weight of the molten metal adhered onto the metal strip; and controlling the shape of the metal strip using magnetic force in non-contact state directly before or after the step of adjusting the coating weight. The invention prevents adhesion of dross to the metal strip without degrading the productivity, and thus manufactures a high quality hot-dip plated metal strip.
