A semiconductor device (1) according to the present disclosure includes a semiconductor chip (2), an interposer substrate (3), and a die-bonding material (4) formed in a partially opened annular shape in a plan view. The semiconductor chip (2) includes a region in which an integration density of an electronic circuit is high (23, 24, and 25) and a region in which the integration density is low (22). The semiconductor chip (2) is implemented on the interposer substrate (3). The die-bonding material (4) formed in a partially opened annular shape in a plan view is provided between the region in which the integration density is high (23, 24, and 25) in the semiconductor chip (2) and the interposer substrate (3).
