  • Publication number: 20070267738
    Abstract: Provided is a semiconductor device having a cooling path on its bottom surface. The stack-type semiconductor device having a cooling path comprises a stack-type semiconductor chip comprising a first semiconductor chip and a second semiconductor chip. The first semiconductor chip comprises a first surface in which a circuit unit is formed and a second surface in which a first cooling path is formed, and the second semiconductor chip comprises a first surface in which a circuit unit is formed and a second surface in which a second cooling path is formed. The second surface of the first semiconductor chip and the second surface of the second semiconductor chip are bonded to each other, and a third cooling path is formed in the middle of the stack-type semiconductor chip using the first and second cooling paths. Warpage of the stack-type semiconductor device is suppressed and heat is easily dissipated.
