Abstract
Methods of forming multi-chip semiconductor substrates include forming a first plurality of dicing streets in a first surface of a first semiconductor wafer having a first plurality of bonding sites thereon and forming a second plurality of dicing streets in a first surface of a second semiconductor wafer having a second plurality of bonding sites thereon. The first surfaces of the first and second semiconductor wafers are bonded together so that the first plurality of dicing streets are aligned with the second plurality of dicing streets and the first plurality of bonding sites are matingly received and permanently affixed within the second plurality of bonding sites. A plurality of bonded pairs of semiconductor chips are then formed by planarizing the second surface of the second semiconductor wafer until the second plurality of dicing streets are exposed.
