Abstract
An interposer includes a substantially planar substrate with a slot therethrough. The slot includes a laterally recessed area in only a portion of a periphery thereof at a location that exposes at least a portion of an active surface of the semiconductor die located between a bond pad and an outer periphery of the semiconductor die. The laterally recessed area may facilitate access to the bond pad by apparatus for forming, positioning, or securing intermediate conductive elements. The slot may be formed by forming a first, thin elongated slot through the interposer substrate, then widening a portion thereof. Alternatively, a first, small circular hole may be formed through the interposer substrate, and then an elongated slot having a width that exceeds the diameter of the small circular hole may be formed through the substrate at a location which is continuous with the small circular hole.
