A compliant contact pin assembly, a contactor card, a testing system and methods for making and testing are provided. A compliant contact pin assembly includes a contact pin formed from a portion of a substrate with the contact pin compliantly held suspended within the substrate by a compliant coupling structure. The suspension within the substrate results in a compliant deflection orthogonal to the plane of the substrate. The contact pin assembly is formed by generally thinning the substrate around the contact pin location and then specifically thinning the substrate immediately around the contact pin location for forming a void. The contact pin is compliantly coupled, in one embodiment by compliant coupling material, and in another embodiment by compliantly flexible portions of the substrate.

A semiconductor component includes a base die and a secondary die stacked on and bonded to the base die. The base die includes conductive vias which form an internal signal transmission system for the component, and allow the circuit side of the secondary die to be bonded to the back side of the base die. The component also includes an array of terminal contacts on the circuit side of the base die in electrical communication with the conductive vias. The component can also include an encapsulant on the back side of the base die, which substantially encapsulates the secondary die, and a polymer layer on the circuit side of the base die which functions as a protective layer, a rigidifying member and a stencil for forming the terminal contacts. A method for fabricating the component includes the step of bonding singulated secondary dice to base dice on a base wafer, or bonding a secondary wafer to the base wafer, or bonding singulated secondary dice to singulated base dice.

A probe card for testing a semiconductor wafer, a test method, and a test system employing the probe card are provided. The probe card includes: a substrate; an interconnect slidably mounted to the substrate; and a force applying mechanism for biasing contacts on the interconnect into electrical engagement with contacts on the wafer. The force applying mechanism includes spring loaded electrical connectors that provide electrical paths to the interconnect, and generate a biasing force. The biasing force is controlled by selecting a spring constant of the electrical connectors, and an amount of Z-direction overdrive between the probe card and wafer. The probe card also includes a leveling mechanism for leveling the interconnect with respect to the wafer.

Multi-chip module systems and method of fabrication thereof wherein the equivalent of a failed die of a multi-chip module (MCM) is added to the module in a vacancy position previously constructed with appropriate electrical connections. A variety of different dice may be attached to the same vacancy position of an MCM by means of adapters, wherein each adapter has the same footprint, but different adapters are capable of accommodating different numbers and types of dice.

A method and apparatus for repair of a multi-chip module, such as a memory module, is provided, where at least one redundant or auxiliary chip attach location is provided on the substrate of the multi-chip module. The auxiliary chip attach location preferably provides contacts for attachment of more than one type of replacement semiconductor chip. Accordingly, when one or more chips on the multi-chip module are found to be completely or partially defective, at least one replacement chip can be selected and attached to the auxiliary location to provide additional memory to bring the module back to its design capacity.
