Multi-chip modules including stacked semiconductor dice

Abstract:

Multi-chip modules may include stacked semiconductor devices having spacers therebetween. Discrete conductive elements may extend over the active surface of an underlying semiconductor device from respective bond pads of the underlying semiconductor device, through a space formed by the spacers, to respective contact areas on a substrate. Each discrete conductive element extending through two side openings opposite one another may extend from a respective centrally located bond pad proximate to a central portion of the active surface of the underlying semiconductor device. Each discrete conductive element extending through another, perpendicular opening may extend from a respective peripheral bond pad located proximate to a peripheral portion of the active surface of the underlying semiconductor device.
