The final-bonder is equipped with a warping correction unit that is equipped in parallel with a backup stage with a distance of about 20 mm from such backup stage, and that includes accordion pads for sucking a liquid crystal panel; the backup stage that supports, from the back, the liquid crystal panel when pressure is applied to its outer edge portion at the bonding of semiconductor components; and a pressure head that carries out final bonding of the semiconductor components onto the outer edge portion of the liquid crystal panel by applying pressure and heat to them.
