More Information
Summary:Embodiments relate to forming a conformable interface layers (clayers) on small semiconductor devices, such as light emitting diodes (LEDs) to facilitate adhesion with a pick-up head for operations during the manufacturing of an electronic display. A conformable material is formed in regions between LED dies on a carrier substrate and over the LED dies. A mask is applied over the conformable material to selectively cover the conformable material. Portions of the conformable material are exposed to light to selectively cure or not cure the portions of the conformable material. The conformable material between the LED dies is removed to form a conformable interface layer over each of the LED dies.
