Semiconductor module, power conversion device, and method for manufacturing semiconductor module

A method for manufacturing a semiconductor module, comprising the steps of:

• preparing a base portion provided with a first electrode terminal and a second electrode terminal arranged along a first direction, a third electrode terminal, a fourth electrode terminal, a fifth electrode terminal, and a sixth electrode terminal arranged along a second direction perpendicular to said first direction, and an internal circuit,
• said first electrode terminal being arranged at a position where said first direction intersects with said second direction,
• said third electrode terminal is positioned adjacent to said first electrode along said second direction,
• said fourth electrode terminal, said fifth electrode terminal, and said sixth electrode terminal being AC output terminals or AC input terminals,
• said first electrode terminal being one of an anode terminal and a cathode terminal,
• at least one of said second electrode terminal and said third electrode terminal being the other of said anode terminal and said cathode terminal,
• said second electrode terminal being electrically insulated from said third electrode terminal, and
• the other of said second electrode terminal and said third electrode terminal being also the other of said anode terminal and said cathode terminal or being a non-connection terminal;
• and
• electrically connecting at least one of said second electrode terminal and said third electrode terminal to said internal circuit.
