Abstract
A method of producing a carrier structure for fabricating a stacked-type semiconductor device includes laminating thin plates for a lower carrier associated with an upper carrier. The method includes forming openings in the thin plates by etching or electric discharge machining. The lower carrier includes a magnet that is buried therein and the magnet maintains contact between the lower carrier and the upper carrier. A thin plate of the laminated thin plates is provided on each opposing surface of the magnet. The lower carrier further includes multiple magnets arranged around a periphery of the lower carrier and through a center region of the lower carrier that is between magnets on the periphery.
