A surface acoustic wave package comprises a first bare chip having a
plurality of electrodes formed thereon, a second bare chip having a
plurality of electrodes and via-holes formed thereon, a connecting
portion electrically connecting the first bare chip to an upper surface
of the second bare chip such that the electrodes of the first bare chip
face the electrodes of the second bare chip, and a sealing member
provided on the first and second bare chips to form an air-tight space on
an operating surface between the first and second bare chips.
