91‐3: Placement Accuracy of MicroLEDs in the 5µm Size Range Being Laser Mass Transferred

91‐3: Placement Accuracy of MicroLEDs in the 5µm Size Range Being Laser Mass Transferred

MicroLED displays require device placement accuracies that meet the dimensional restrictions of the contact pads. We will report on accuracies achieved by a laser forward transfer (LIFT) system with dies in the 5μm size range over gap distances around 10‐20 times the thickness of the devices and dis...

Zusammenfassung:MicroLED displays require device placement accuracies that meet the dimensional restrictions of the contact pads. We will report on accuracies achieved by a laser forward transfer (LIFT) system with dies in the 5μm size range over gap distances around 10‐20 times the thickness of the devices and discuss the implications thereof.
