  • Patent number: 10395966
    Abstract: In certain embodiments, a method of making a semiconductor structure suitable for transfer printing (e.g., micro-transfer printing) includes providing a support substrate and disposing and processing one or more semiconductor layers on the support substrate to make a completed semiconductor device. A patterned release layer and, optionally, a capping layer are disposed on or over the completed semiconductor device and the patterned release layer or capping layer, if present, are bonded to a handle substrate with a bonding layer. The support substrate is removed to expose the completed semiconductor device and, in some embodiments, a portion of the patterned release layer. In some embodiments, an entry path is formed to expose a portion of the patterned release layer. In some embodiments, the release layer is etched and the completed semiconductor devices transfer printed (e.g., micro-transfer printed) from the handle substrate to a destination substrate.

  • Publication number: 20190229231
    Abstract: A transfer-printable (e.g., micro-transfer-printable) device source wafer comprises a growth substrate comprising a growth material, a plurality of device structures comprising one or more device materials different from the growth material, the device structures disposed on and laterally spaced apart over the growth substrate, each device structure comprising a device, and a patterned dissociation interface disposed between each device structure of the plurality of device structures and the growth substrate. The growth material is more transparent to a desired frequency of electromagnetic radiation than at least one of the one or more device materials. The patterned dissociation interface has one or more areas of relatively greater adhesion each defining an anchor between the growth substrate and a device structure of the plurality of device structures and one or more dissociated areas of relatively lesser adhesion between the growth substrate and the device structure of the plurality of device structures.

  • Publication number: 20190157532
    Abstract: A transfer print structure comprises a destination substrate having a substrate surface and one or more substrate conductors disposed on or in the destination substrate. One or more interconnect structures are disposed on and protrude from the destination substrate in a direction orthogonal to the substrate surface. Each interconnect structure comprises one or more notches, each notch having an opening on an edge of the interconnect structure and extending at least partially through the interconnect structure in a direction parallel to the substrate surface from the edge and a notch conductor disposed at least partially in the notch and electrically connected to one of the substrate conductors. In some embodiments, an electronic component comprising connection posts is transfer printed into electrical contact with a corresponding notch conductor by laterally moving the electrical component over the substrate surface to electrically contact the connection post to the notch conductor.

  • Publication number: 20190051552
    Abstract: An exemplary wafer structure comprises a source wafer having a patterned sacrificial layer defining anchor portions separating sacrificial portions. A patterned device layer is disposed on or over the patterned sacrificial layer, forming a device anchor on each of the anchor portions. One or more devices are disposed in the patterned device layer, each device disposed entirely over a corresponding one of the one or more sacrificial portions and spatially separated from the one or more device anchors. A tether structure connects each device to a device anchor. The tether structure comprises a tether device portion disposed on or over the device, a tether anchor portion disposed on or over the device anchor, and a tether connecting the tether device portion to the tether anchor portion. The tether is disposed at least partly in the patterned device layer between the device and the device anchor.

  • Publication number: 20180323178
    Abstract: An exemplary micro-device and substrate structure includes a destination substrate and one or more contact pads disposed thereon, a micro-device disposed on or over the destination substrate, and a layer of cured adhesive disposed on the destination substrate. The micro-device comprises at least one electrical contact. The at least one electrical contact is in direct electrical contact with the one or more contact pads. The adhesive layer adheres the micro-device to the destination substrate and is in contact with the one or more contact pads. An exemplary method of making a micro-device and substrate structure includes providing a destination substrate and one or more contact pads disposed thereon, coating a layer of curable adhesive, disposing a micro-device comprising at least one electrical contact on the layer and curing the layer thereby directly electrically contacting the at least one electrical contact with the one or more contact pads.

  • Publication number: 20180286734
    Abstract: A method of micro-transfer printing a micro-device from a support substrate comprises providing the micro-device, forming a pocket in or on the support substrate, providing a release layer over the micro-device or the pocket, optionally providing a base layer on a side of the release layer opposite the micro-device, disposing the micro-device in the pocket with the release layer between the micro-device and the support substrate so that no portion of the support substrate or the optional base layer is in contact with the micro-device, etching the release layer to completely separate the micro-device from the support substrate or the optional base layer, providing a stamp having a conformable stamp post and pressing the stamp post against the separated micro-device to adhere the micro-device to the stamp post, and removing the stamp and micro-device from the support substrate.
