Abstract
A microelectronic assembly and related method of forming a through hole extending through a first chip and a second chip are provided. The first and second chip have confronting faces, metallic features join the first and second chips leaving a gap chips. A first etch creates a hole through the first chip. The hole has a first wall extending in a vertical direction, and a second wall sloping inwardly from the first wall to an inner opening to expose the gap. Material of the first or second chips exposed within the hole is sputtered to form a wall in the gap. A second etch extends the hole into the second chip. An electrically conductive through silicon via can then be formed extending through the first chip, the wall between the chips and into the second chip.
