Claim:
1. A method for manufacturing a device, providing a first member that has a first substrate including a first transistor and has a first structure including a first insulating film on the first substrate and a first conductive portion disposed in a groove of the first insulating film, the first structure having a first face formed by an upper face of the first insulating film and an upper face of the first conductive portion; providing a second member that has a second substrate including a second transistor and has a second structure including a second insulating film on the second substrate and a second conductive portion disposed in a groove of the second insulating film, the second structure having a second face formed by an upper face of the second insulating film and an upper face of the second conductive portion; and bonding the first member and the second member so that the first structure and the second structure are arranged between the first substrate and the second substrate, and so that the first conductive portion and the second conductive portion form an electrical connection; wherein the second face has a concave portion formed by the upper face of the second conductive portion, and the upper face of the second conductive portion has a concave shape.
