    摘要: In a manufacturing method of a semiconductor device, a semiconductor substrate having a plurality of semiconductor chips formed on one of principal surfaces of the substrate is cut into the plurality of semiconductor chips through dicing. A first cutting process is formed on one of the principal surfaces of the substrate to produce two cutting grooves between two neighboring ones of the plurality of semiconductor chips, each cutting groove being adjacent to one of the neighboring ones of the plurality of semiconductor chips. A second cutting process is performed on the other of the principal surfaces of the substrate to produce a cutting groove overlapping the two cutting grooves produced by the first cutting process.

    摘要: There is provided a chamber open to the outside through openings through which a solder-adhered object is passed and the chamber having a heating/melting area, a carrying mechanism for carrying the solder-adhered object into the heating/melting area, a formic-acid supplying means for supplying a formic acid into the heating/melting area, an exhausting means for exhausting a gas from the heating/melting area and its neighboring area to create a lower pressure area in the heating/melting area as compared to the pressure of outside the chamber, heating means for heating directly or indirectly the solder-adhered object in the heating/melting area, and an air-stream suppressing means for disturbing a gas flow between the heating/melting area and the carrying areas. Accordingly, there can be provided a solder jointing system for jointing solder layers of a semiconductor device, an electronic device, or the like to the wirings or the pads, which is capable of having a high processing ability and preventing re-oxidation.
