Abstract

See full text

According to one embodiment, a semiconductor device includes a semiconductor element, a mounting member including Cu, and a bonding layer provided between the semiconductor element and the mounting member. The bonding layer includes a first region including Ti and Cu, and a second region provided between the first region and the mounting member, and including Sn and Cu. A first position along the first direction is positioned between the semiconductor element and a second position along the first direction. The first position is where the composition ratio of Ti in the first region is 0.1 times a maximum value of the composition ratio of Ti. The second position is where the composition ratio of Sn in the second region is 0.1 times a maximum value of the composition ratio of Sn. A distance between the first position and the second position is not less than 0.1 micrometers.
