  • Publication number: 20070167000
    Abstract: A semiconductor component includes a semiconductor substrate having a substrate contact, and a through wire interconnect (TWI) bonded to the substrate contact. The through wire interconnect (TWI) includes a via through the substrate contact and the substrate, a wire in the via bonded to the substrate contact, and a contact on the wire. A stacked semiconductor component includes the semiconductor substrate, and a second semiconductor substrate stacked on the substrate and bonded to a through wire interconnect on the substrate. A method for fabricating a semiconductor component with a through wire interconnect includes the steps of providing a semiconductor substrate with a substrate contact, forming a via through the substrate contact and part way through the substrate, placing the wire in the via, bonding the wire to the substrate contact, and then thinning the substrate from a second side to expose a contact on the wire.

  • Publication number: 20070132104
    Abstract: 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.

  • Publication number: 20070088451
    Abstract: An inventive method in an integrated circuit (IC) manufacturing process for using data regarding repair procedures conducted on ICs at probe to determine whether any further repairs will be conducted later in the manufacturing process includes storing the data in association with a fuse ID of each of the ICs. The ID codes of the ICs are automatically read, for example, at an opens/shorts test during the manufacturing process. The data stored in association with the ID codes of the ICs is then accessed, and additional repair procedures the ICs may undergo are selected in accordance with the accessed data. Thus, for example, the accessed data may indicate that an IC is unrepairable, so the IC can proceed directly to a scrap bin without having to be queried to determine whether it is repairable, as is necessary in traditional IC manufacturing processes.

  • Publication number: 20060244475
    Abstract: A compliant contact pin assembly and a contactor card and methods for testing therewith are provided. The 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.
