26‐3: Pyramidal MicroLEDs in the Same Material System Delivering RGB

An innovative microLED technology based on a novel bottom‐up growth technique is demonstrated. The novel technology allows for overcoming main fundamental limitations hindering further development of microLEDs. The technology allows for RGB emission within a single materials system (InGaN/GaN). Blue and green emissions have earlier been demonstrated, but now also a red emission peaking at 635nm is realized. The technology is suited for hybridization with extremely high accuracy, using a cold‐bonding flip‐chip method. MicroLED technology based on the pyramidal architecture is promising for manufacturing of micro displays for applications such as Head‐Mounted‐Displays (HMDs) and Head‐Up‐Displays (HUDs).
