Semiconductor device with extraction electrode

A semiconductor device comprising:

• a power semiconductor element comprising first and second main electrodes respectively formed on a front surface and a rear surface thereof;
• a metal plate electrically connected to said second main electrode of said power semiconductor element;
• first and second connection electrodes formed separately on said first main electrode to be opposed to each other;
• and
• an extraction electrode comprising a first electrode interconnection part formed to extend downwardly from one side portion thereof and a second electrode interconnection part formed separately from said first electrode interconnection part to extend downwardly from the other side portion thereof opposed to said one side portion so as to be opposed to said first electrode interconnection part, wherein
• said first electrode interconnection part is electrically connected only to said first connection electrode, and
• said second electrode interconnection part is electrically connected only to said second connection electrode.
