Abstract: A multi-chip package is disclosed that has a construction capable of preventing and/or reducing electrical shorts caused by shifts in bond wires. The multi-chip package includes a die attach formed between connection points of a bond wire. The die attach is made of a non-conductive material and can be constructed so as to support or encompass a portion of the bond wire. By contacting the bond wire, the die attach restricts the motion of the bond wire by acting as a physical barrier to the bond wire's movement and/or as a source of friction. In this manner, undesired position shifts of the bond wires can be prevented, reducing device failures and allowing for improved manufacturing allowances.

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.
