Claim:
1. A semiconductor module, comprising: a semiconductor element having a first main surface and a second main surface facing said first main surface, the semiconductor element including a front surface electrode and a back surface electrode on said first main surface and said second main surface, respectively; a metal plate electrically connected to said back surface electrode of said semiconductor element through a sintered bonding material including metal nanoparticles, the location of the sintered bonding material on a surface of the metal plate being a bonding region; and a plate-shaped conductor electrically connected to said front surface electrode of said semiconductor element through the sintered bonding material including the metal nanoparticles, the location of the sintered bonding material on a surface of the plate-shaped conductor being another bonding region, wherein said metal plate and said plate-shaped conductor each include a plurality of first conductive paths extending along each said respective surface of said metal plate and said plate-shaped conductor from outside said respective bonding region bonded to said semiconductor element, across said respective bonding region, and extending outside of said respective bonding region such that at least one of the plurality of the first conductive paths extends from a first side of said semiconductor element to a second side of said semiconductor element, and at least one of the plurality of first conductive paths extends from a third side of said semiconductor element to a fourth side of said semiconductor element, wherein said metal plate and said plate-shaped conductor each include a plurality of second conductive paths extending along each said respective surface of said metal plate and said plate-shaped conductor, with at least one conductive path of said second conductive paths extending from a first edge of said respective surface of said metal plate and said plate-shaped conductor to a second edge opposite to the first edge of said respective surface of said metal plate and said plate-shaped conductor, and at least one conductive path of said second conductive paths extending along each said respective surface of said metal plate and said plate-shaped conductor from a third edge of said respective surface of said metal plate and said plate-shaped conductor that is different from the first and second edge to a fourth edge opposite to the third edge of said respective surface of said metal plate and said plate-shaped conductor, each of said plurality of second conductive paths intersecting at least one of the first plurality of conductive paths at a location outside said respective bonding region and each of said plurality of second conductive paths being non-intersecting with any bonding region, wherein each said conductive path of the first plurality of conductive paths and the second plurality of conductive paths opens onto each said respective surface of said metal plate and said plate-shaped conductor facing said semiconductor element in all regions of said metal plate and said plate-shaped conductor, wherein said first plurality of conductive paths is a first plurality of grooves, wherein said second plurality of conductive paths is a second plurality of grooves, and wherein each of said first plurality of grooves has a width greater than a width of each of said second plurality of grooves.
