Abstract
Provided is a semiconductor device that can improve yield and non-defective rate by obtaining the thickness of a melt-bonding material and suppressing inclination of a circuit board. The semiconductor device includes a circuit board including a circuit pattern layer, a semiconductor element mounted on the circuit board, a melt-bonding portion arranged on an upper surface of the circuit pattern layer, a bonding lead including a bonding portion facing the upper surface of the circuit pattern layer and electrically connected to the circuit pattern layer via the melt-bonding portion, and a pressing portion directly contacted with an upper surface of the circuit board.
