2021 7th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D).
The luminous flux and temperature characteristics of InGaN-based white light-emitting diodes (LEDs) intended for automotive headlamps were greatly enhanced by bonding a yellow phosphor to the LED chip using surface activated bonding. The performance

This paper deals with a flexible 3D-IC system fabrication methodology. Mini-LEDs and 3D-IC chiplets divided from a large 3D-IC with Cu-TSVs are embedded in an elastomer PDMS based on die-first FOWLP for heterogeneously integrating them into Smart Ski

AlGaN-based light-emitting diodes (LEDs) are attractive candidates for next-generation light sources in the deep ultraviolet (DUV) region because they can cover the spectral range of 210 – 365 nm through control of the Al content in the epitaxial l

2017 5th International Workshop on Low Temperature Bonding for 3D Integration (LTB-3D).
Enhancement of light transmittance was examined for sapphire or synthetic quartz glass wafers bonded with thin Al films using atomic diffusion bonding (ADB). The results indicate that the thin Al film at the bonded interface diffuses into the wafer b

We fabricated three types of high luminous efficiency white light emitting diodes (LEDs). The first is the white LED, which had a high luminous efficiency (ηL) of 161 lm/W with the high luminous flux (v) of 9.89 lm at a forward-bias current of 20 mA

We fabricated high-output-power 255 and 280 nm light-emitting diodes (LEDs) using direct bonding. The LED chips were bonded to sapphire lenses at room temperature using either atomic diffusion bonding or surface-activated bonding. The LEDs with lense
