Abstract:
A semiconductor device includes unit circuits arranged in a first direction, a bonding pad, and electrically conductive patterns configured to connect the unit circuits to the bonding pad. Each of the electrically conductive patterns includes a first portion connected to the bonding pad and extending in the first direction, and a second portion connected to the corresponding unit circuit. The electrically conductive patterns include a first type pattern in which the first portion is positioned on a first side of the second portion in a view from the first direction, and a second type pattern in which the first portion is positioned on a second side, which is opposite to the first side, of the second portion in a view from the first direction.
