  • MICROELECTRONIC DEVICE TRANSFER WITH UV-TRANSMISSIVE ADHESIVE AND LASER LIFT-OFF
    Publication number: 20240088323
    Abstract: A method for inter-substrate transfer of microelectronic devices includes applying a polymer coating to a top surface of a microelectronic device located on a first substrate, depositing an ultraviolet-transmissive adhesive on a second substrate, contacting the polymer-coated top surface of the microelectronic device to the adhesive to bond the microelectronic device to the second substrate, detaching the microelectronic device from the first substrate, and, while the bottom surface of the microelectronic device faces a third substrate, irradiating and ablating the polymer coating with ultraviolet laser light through the second substrate and the adhesive to transfer the microelectronic device from the second substrate to the third substrate via laser lift-off.
