Abstract: A method for backside metallization includes inkjet printing a pattern of nanosilver conductive ink on a first surface of a silicon wafer. The silicon wafer includes a plurality of dies. The pattern includes a clearance area along a scribe line between the dies. A laser is focused, through a second surface of the wafer, at a point between the first surface of the silicon wafer and the second surface of the silicon wafer. The second surface is opposite the first surface. The dies are separated along the scribe line.

Abstract: A described example includes: a MEMS component on a device side surface of a first semiconductor substrate; a second semiconductor substrate bonded to the device side surface of the first semiconductor substrate by a first seal patterned to form sidewalls that surround the MEMS component; a third semiconductor substrate having a second seal extending from a surface and bonded to the backside surface of the first semiconductor substrate by the second seal, the second seal forming sidewalls of a gap beneath the MEMS component. A trench extends through the first semiconductor substrate and at least partially surrounds the MEMS component. The third semiconductor substrate is mounted on a package substrate. A bond wire or ribbon bond couples the bond pad to a conductive lead on the package substrate; and mold compound covers the MEMS component, the bond wire, and a portion of the package substrate.
