  • Patent number: 8389378
    Abstract: A method of three-dimensionally integrating elements such as singulated die or wafers and an integrated structure having connected elements such as singulated dies or wafers. Either or both of the die and wafer may have semiconductor devices formed therein. A first element having a first contact structure is bonded to a second element having a second contact structure. First and second contact structures can be exposed at bonding and electrically interconnected as a result of the bonding. A via may be etched and filled after bonding to expose and form an electrical interconnect to interconnected first and second contact structures and provide electrical access to this interconnect from a surface. Alternatively, first and/or second contact structures are not exposed at bonding, and a via is etched and filled after bonding to electrically interconnect first and second contact structures and provide electrical access to interconnected first and second contact structure to a surface.

  • Publication number: 20120097638
    Abstract: A method for bonding at low or room temperature includes steps of surface cleaning and activation by cleaning or etching. The method may also include removing by-products of interface polymerization to prevent a reverse polymerization reaction to allow room temperature chemical bonding of materials such as silicon, silicon nitride and SiO2. The surfaces to be bonded are polished to a high degree of smoothness and planarity. VSE may use reactive ion etching or wet etching to slightly etch the surfaces being bonded. The surface roughness and planarity are not degraded and may be enhanced by the VSE process. The etched surfaces may be rinsed in solutions such as ammonium hydroxide or ammonium fluoride to promote the formation of desired bonding species on the surfaces.

  • Patent number: 7956447
    Abstract: A waffle pack device including a member having recesses in a surface of the member to accommodate die from at least one semiconductor wafer. The member is compatible with semiconductor wafer handling equipment and/or semiconductor wafer processing. Preferably, the member accommodates at least a majority of die from a semiconductor wafer. Further, one semiconductor device assembly method is provided which removes die from a singular waffle pack device, places die from the single waffle pack device on a semiconductor package to assemble from the placed die all die components required for an integrated circuit, and electrically interconnects the placed die in the semiconductor package to form the integrated circuit.

  • Patent number: 7714446
    Abstract: A method of connecting elements such as semiconductor devices and a device having connected elements such as semiconductor devices. A first element having a first contact structure is bonded to a second element having a second contact structure. A single mask is used to form a via in the first element to expose the first contact and the second contact. The first contact structure is used as a mask to expose the second contact structure. A contact member is formed in contact with the first and second contact structures. The first contact structure may have an aperture or gap through which the first and second contact structures are connected. A back surface of the first contact structure may be exposed by the etching.

  • Patent number: 7622324
    Abstract: A method for providing encapsulation of an electronic device which obtains an encapsulating member configured to enclose the electronic device, prepares a surface of the encapsulating member for non-adhesive direct bonding, prepares a surface of a device carrier including the electronic device for non-adhesive direct bonding, and bonds the prepared surface of the encapsulating member to the prepared surface of the device carrier to form an encapsulation of the electronic device. As such, an encapsulated electronic device results which includes the device carrier having a first bonding region encompassing the electronic device, includes the encapsulating member having at least one relief preventing contact between the electronic device and the encapsulating member and having a second bonding region bonded to the first bonding region of the device carrier, and includes a non-adhesive direct bond formed between the first and second bonding regions thereby to form an encapsulation of the electronic device.
