  • Patent number: 10468472
    Abstract: In a micro-device integration process, a donor substrate is provided on which to conduct the initial manufacturing and pixelation steps to define the micro devices, including functional, e.g. light emitting layers, sandwiched between top and bottom conductive layers. The micro-devices are then transferred to a system substrate for finalizing and electronic control integration. The transfer may be facilitated by various means, including providing a continuous light emitting functional layer, breakable anchors on the donor substrates, temporary intermediate substrates enabling a thermal transfer technique, or temporary intermediate substrates with a breakable substrate bonding layer.
    Type: Grant

  • Publication number: 20190288156
    Abstract: A microdevice structure comprising at least part of an edge of a microdevice is covered with a metal-insulator-semiconductor (MIS) structure, wherein the MIS structure comprises a MIS dielectric layer and a MIS gate conductive layer, at least one gate pad provided to the MIS gate conductive layer, and at least one micro device contact extended upwardly on a top surface of the micro device.

  • Publication number: 20180358405
    Abstract: Post-processing steps for integrating of micro devices into system (receiver) substrate or improving the performance of the micro devices after transfer. Post processing steps for additional structures such as reflective layers, fillers, black matrix or other layers may be used to improve the out coupling or confining of the generated LED light. Dielectric and metallic layers may be used to integrate an electro-optical thin film device into the system substrate with transferred micro devices. Color conversion layers may be integrated into the system substrate to create different outputs from the micro devices.

  • Publication number: 20180095124
    Abstract: This disclosure is related to arranging micro devices in the donor substrate by either patterning or population so that there is no interfering with non-receiving pads and the non-interfering area in the donor substrate is maximized. This enables the transfer of micro devices to a receiver substrate with fewer steps.
