An integrated type semiconductor device that is capable of reducing cost or improving the reliability of connecting semiconductor chips together or chips to a circuit board. One embodiment of such an integrated type semiconductor device comprises a first semiconductor device (

10

) having a semiconductor chip (

12

) with electrodes (

16

), a stress-relieving layer (

14

) prepared on the semiconductor chip (

12

), a wire (

18

) formed across the electrodes (

16

) and the stress-relieving layer (

14

), and solder balls (

19

) formed on the wire (

18

) over the stress-relieving layer (

14

); and a bare chip (

20

) as a second semiconductor device to be electrically connected to the first semiconductor device (

10

).
