Abstract:
A method involves stacking a first chip, comprising high-speed circuitry formed using a first fabrication process, together with a wafer comprising multiple iterations of low-speed circuitry formed using a second fabrication process, hybridizing the first chip to the wafer so as to form electrical connections between the first chip and one of the iterations of the low-speed circuitry so as to form a hybridized unit and dicing the unit from the wafer.
Abstract:
An apparatus for use with multiple chips having multiple posts as to engage at least a portion of a surface of one of the multiple chips, a frame configured to releasably constrain each of the posts so that, when unconstrained, each individual post can contact an individual chip and, when constrained, will allow a uniform vertical force to be applied to the chips.
Abstract:
A method of electrically joining a first contact on a first wafer with a second contact on a second wafer, the first contact, a rigid material, and the second contact, a material that is malleable relative to the rigid material, such that when brought together the rigid material will penetrate the malleable material, the rigid and malleable materials both being electrically conductive involves bringing the rigid material into contact with the malleable material, applying a force to one of the first contact or the second contact so as to cause the rigid material to penetrate the malleable material, heating the rigid and malleable material so as to cause the malleable material to soften, and constraining the malleable material to within a pre-specified area.
Abstract:
A method of joining contacts on two chips, each having multiple contacts, to each other involves maintaining a first of the chips at a first temperature, the first of the chips having a rigid electrical contact thereon, bringing a second chip, having an electrical contact that is malleable with respect to the rigid contact and matingly corresponding thereto, into contact with the first such that the corresponding rigid and malleable contacts are brought together, locally raising the second of the chips to a local temperature that is sufficiently high to cause material of the rigid and malleable contact to interdiffuse, interpenetrate or both, but below both a temperature that would cause the material to become liquidus and a fuse temperature, and allowing the second of the chips to cool to at least the first temperature.
Abstract:
A multi-wavelength laser array has a group of multiple lasers, each of the lasers in the group being constructed to emit at a specified wavelength within a range, the specified wavelength of one laser being different form the specified wavelength of the other lasers in the group. The lasers in the group are individually selectable so that, when emission at a particular wavelength is called for, a laser capable of providing the particular wavelength will be selected.
Abstract:
A coupler adapter (320, 620) for attaching a multi-fiber connector (330, 630) holding fiber bundles (340, 640) to an opto-electronic module (300) when the size of the opto-electronic component (310, 610) for the module (300) is larger than the spacing of the high precision alignment elements (332) used in commercial connectors (330). The adapter includes alignment features (324, 410), for example guide pins, that may be mounted on a base (328) of the adapter (320, 620) or directly to the module (300). A window (322) may be used on the base (328) to permit transmission of optical signals for the fiber bundles (340, 640) to interact with the opto-electronic module (300).
