Project description
Big plans for smaller pixel sizes
LED technology has surpassed many traditional lighting methods and is now widely used in electronics for displays and other applications. However, further advancement in the field requires innovations that will enable the production of smaller and smaller LEDs. The EU-funded InGaNious project aims to research and develop a solution. It will focus on the development of innovative indium gallium nitride (InGaN) microLEDs. By using a unique production process, the project will develop pure InGaN microLEDs that are even smaller than current alternatives, with sub 2 μm pixel sizes. This breakthrough will enable the creation of highly efficient and high-quality displays that can be used in a wide range of applications.
Objective
Our method of growing pure InGaN μLEDs is completely unique. We start with a layer of thin GaN on a substrate. This layer has the same high defect density that other existing technologies struggle with. Then we add a mask made of either silicon nitride or aluminum oxide introduced by us using a high-resolution lithography process. The mask contains tiny holes ca. 100 nm in diameter which become growth sites for intrinsically defect-free InGaN pyramids. These pyramids are then reshaped into truncated hexagonal pyramids, aka InGaN platelets that are just 700 nm wide (effectively a nanoLED) and contain the active micro LED structure after regrowth on the top c-plane of the InGaN platelets.
We can already grow the μLEDs on 2” wafers on a sapphire substrate, and we are developing new methods to grow 4” wafers on a silicon substrate. Our KPIs (pixel size <1 µm, internal quantum efficiency >3.5%, FWHM <50 nm, etc.) already outcompete current commercial options for sub-2 µm-pixel size.
