Abstract: A plurality of contact elements, such as contact bumps or free-standing spring contacts including both monolithic and composite interconnection elements (514, 516, 524), are mounted to relatively small tile substrates which, in turn, are mounted and connected to a relatively large electronic component substrate (512), thereby populating the electronic component with a plurality of contact elements while avoiding the necessity of yielding the contact elements directly upon the electronic component. The relatively large electronic component is suitably a space transformer (506) component of a probe card assembly (500). In this manner, pressure connections can be made to an entire semiconductor wafer, at once, to provide for wafer-level burn-in, and the like. Solder balls, Z-axis conductive adhesive, or compliant connections are suitably employed for making electrical connections between the tile substrates and the electronic component. Multiple die sites on a semiconductor wafer (508) are readily probed using the disclosed techniques, and the tiles can be arranged to optimize probing of an entire wafer. Composite interconnection elements having a relatively soft core overcoated by a relatively hard shell, as the resilient contact structures are described. Techniques for maintaining a prescribed X-Y and Z-axis alignment of the tiles to the relatively large substrate are disclosed.

Abstract: Interconnection elements (752) and/or tip structures (770) for interconnection elements (752) may first be fabricated upon sacrificial substrates (702) for subsequent mounting to electronic components (784). In this manner, the electronic components (784) are not 'at risk' during the fabrication process. The sacrificial substrate (702) establishes a predetermined spatial relationship between the interconnection elements (752) which may be composite interconnection elements (752) having a relatively soft elongate element (752) as a core and a relatively hard (springy material) overcoat (754). Interconnection elements (752) may be fabricated upon tip structures (770), or may first be mounted to the electronic component (784) and the tip structures (770) joined to the free-ends of the interconnection elements (752). Tip structures (770) formed as cantilever beams are described.
