Abstract
An integrated circuit package or arrangement includes a carrier having a surface topography of projections or recesses for supporting individual semiconductor circuit chips having conversely matching bottom surface topographies to permit self-aligned positioning of the chips on the carrier. Top faces of neighboring chips lie substantially in planes separated by a distance of greater than 0.0 .mu.m. The neighboring chips are separated by a gap G or spacing in a range of approximately 1 .mu.m<G.ltoreq.approximately 100 .mu.m. A metallic interconnect is disposed over the top faces and the gap. Preferably, the interconnect has a gradual slope over the gap.
