Near size-independent UV-A micro-LED performance

University of Wisconsin-Madison in the USA reports on atomic layer deposition (ALD) passivation as a means to overcome the impact of sidewall damage on micron-scale light-emitting diodes (micro-LEDs), resulting in near size-independent performance between 8μm and 100μm [Guangying Wang et al, physica status solidi (RRL) published online 23 May 2024]. The researchers comment on smaller devices: “Micro-LEDs have the potential to show higher stability under high current density while providing a higher light extraction efficiency and output power than regula...

Picosun increases efficiency for LED and OLED production

ESPOO, Finland, April 13, 2021 /PRNewswire/ -- Picosun Group has proved to significantly increase the production efficiency of its LED and OLED customers with the PICOSUN® P-300BV ALD system. Recent tests show that a reduced ALD process cycle time and an increased number of wafers deposited with the same film thickness resulted in almost 100% better throughput. A throughput of over 20 000 wafers per month can be reached with a wafer batch of 100 wafers*. At the same time, the process quality in terms of film thickness uniformity has remained on an...
