Conductors are applied in the vias for ohmic contacts for the source-drain and a Schottky contact for the gate. Interconnections over the edges of the mesa couple other circuit elements. PL-1 avoids adverse surface states near the gate and PL-2 insulates edges of the mesa from overlying interconnections to avoid leakage currents.

  • Patent number: 8846494
    Abstract: An imaging system may include an imager integrated circuit with frontside components such as imaging pixels and backside components such as color filters and microlenses. The imager integrated circuit may be mounted to a carrier wafer with alignment marks. Bonding marks on the carrier wafer and the imager integrated circuit may be used to align the carrier wafer accurately to the imager integrated circuit. The alignment marks on the carrier wafer may be read, by fabrication equipment, to align backside components of the imager integrated circuit, such as color filters and microlenses, with backside components of the imager integrated circuit, such as photodiodes.

  • Patent number: 8836100
    Abstract: An arrangement for improving adhesive attachment of micro-components in an assembly utilizes a plurality of parallel-disposed slots formed in the top surface of the substrate used to support the micro-components. The slots are used to control the flow and “shape” of an adhesive “dot” so as to quickly and accurately attach a micro-component to the surface of a substrate. The slots are formed (preferably, etched) in the surface of the substrate in a manner that lends itself to reproducible accuracy from one substrate to another. Other slots (“channels”) may be formed in conjunction with the bonding slots so that extraneous adhesive material will flow into these channels and not spread into unwanted areas.

  • Patent number: 8829661
    Abstract: Methods and apparatus are provided for an electronic panel assembly (EPA) (82, 83), comprising: providing one or more electronic devices (30) with primary faces (31) having electrical contacts (36), opposed rear faces (33) and edges (32) therebetween. The devices (30) are mounted primary faces (31) down on a temporary support (60) in openings (44) in a warp control sheet (WCS) (40) attached to the support (60). Plastic encapsulation (50) is formed at least between lateral edges (32, 43) of the devices (30) and WCS openings (44). Undesirable panel warping (76) during encapsulation is mitigated by choosing the WCS coefficient of thermal expansion (CTE) to be less than the encapsulation CTE. After encapsulation cure, the EPA (82) containing the devices (30) and the WCS (40) is separated from the temporary support (60) and, optionally, mounted on another carrier (70) with electrical contacts (36) exposed.

  • Patent number: 8822343
    Abstract: An overlay mark suitable for use in manufacturing nonplanar circuit devices and a method for forming the overlay mark are disclosed. An exemplary embodiment includes receiving a substrate having an active device region and an overlay region. One or more dielectric layers and a hard mask are formed on the substrate. The hard mask is patterned to form a hard mask layer feature configured to define an overlay mark fin. Spacers are formed on the patterned hard mask layer. The spacers further define the overlay mark fin and an active device fin. The overlay mark fin is cut to form a fin line-end used to define a reference location for overlay metrology. The dielectric layers and the substrate are etched to further define the overlay mark fin.
