  • Publication number: 20110233777
    Abstract: A through-wafer interconnect for imager, memory and other integrated circuit applications is disclosed, thereby eliminating the need for wire bonding, making devices incorporating such interconnects stackable and enabling wafer level packaging for imager devices. Further, a smaller and more reliable die package is achieved and circuit parasitics (e.g., L and R) are reduced due to the reduced signal path lengths.

  • Publication number: 20080042247
    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: 20070246819
    Abstract: A semiconductor component includes a semiconductor substrate having a substrate contact, and a through wire interconnect (TWI) attached to the substrate contact. The through wire interconnect provides a multi level interconnect having contacts on opposing first and second sides of the semiconductor substrate. The through wire interconnect (TWI) includes a via through the substrate contact and the substrate, a wire in the via having a bonded connection with the substrate contact, a first contact on the wire proximate to the first side, and a second contact on the wire proximate to the second side. The through wire interconnect (TWI) also includes a polymer layer which partially encapsulates the through wire interconnect (TWI) while leaving the first contact exposed. The semiconductor component can be used to fabricate stacked-systems, module systems and test systems. A method for fabricating the semiconductor component can include a film assisted molding process for forming the polymer layer.

  • Publication number: 20070241078
    Abstract: Methods and apparatuses for releasably attaching support members to microfeature workpieces to support members are disclosed herein. In one embodiment, for example, a method for processing a microfeature workpiece including a plurality of microelectronic dies comprises forming discrete blocks of material at a first side of a support member. The blocks are arranged on the support member in a predetermined pattern. The method also includes depositing an adhesive material into gaps between the individual blocks of material and placing a first side of the workpiece in contact with the adhesive material and/or the blocks. The method further includes cutting through a second side of the workpiece to singulate the dies and to expose at least a portion of the adhesive material in the gaps. The method then includes removing at least approximately all the adhesive material from the support member and/or the workpiece with a solvent.

  • Publication number: 20070200575
    Abstract: A contactor card assembly for use with a semiconductor substrate. An upper keeper plate and a lower keeper plate each include a number of conductive pins extending therethrough, situated in vias filled with an elastomeric material and extending beyond the keeper plates to contact a substrate for testing. An intermediate keeper plate is situated between the upper and lower keeper plates and includes conductive pivot bars in channels filled with elastomeric material. Each conductive pin contacts a pivot bar on one side thereof to electrically communicate with a corresponding pin on the opposite side. Under compression, variations in the height of contacts on the substrate under test are adjusted for by the movement of the pins and pivoting of the pivot bar in the elastomeric material. Methods and process for creating the keeper plates and semiconductor and testing assemblies are also included in the present invention.

  • 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.
