Semiconductor device

A semiconductor device comprising:

• at least one semiconductor element having a first main electrode disposed on one surface side, and a second main electrode disposed on a back surface side opposite to the one surface side in a thickness direction;
• a substrate arranged to sandwich the semiconductor element and having a first substrate arranged on the one surface side and electrically connected to the first main electrode, and a second substrate arranged on the back surface side and electrically connected to the second main electrode;
• a main terminal including at least one first main terminal electrically connected to the first main electrode via the first substrate, and at least one second main terminal electrically connected to the second main electrode via the second substrate;
• and
• a bonding member, wherein:
• the bonding member is interposed between the first main electrode and the first substrate, and between the second main electrode and the second substrate, respectively;
• at least one of the first main terminal and the second main terminal in the main terminal includes a plurality of terminals;
• the first main terminal and the second main terminal are alternately arranged, and a side surface of the first main terminal and a side surface of the second main terminal face each other in a direction orthogonal to the thickness direction of the semiconductor element;
• the first main terminal is directly bonded to the second substrate without the bonding member and
• the second main terminal is directly bonded to the second substrate without the bonding member.
