Surface processing challenges for organic and hybrid optoelectronics
life on Tuesday 13th April, UTC+2: 12h40 – 13h10 (No. 3.6)

Abstract: Organic and hybrid perovskite optoelectronic devices such as LEDs and solar cells present unique challenges for surface cleaning and preparation because of their large area and the ‘soft’, thin film nature of the materials involved. This talk will give an introduction to this class of semiconductor devices and provide recent examples of how surface processing impacts the efficiency and long-term reliability of organic LEDs being commercialized for solid-state lighting.

GaN MOS Structure with Low Interface Trap Density
life on Tuesday 13th April UTC+2: 14h30 – 15h00 (No. 4.4)


Abstract: GaN based electronic devices have gained great success in the arena of high-frequency and high-power applications. A high-quality GaN MOS structure has the potential to enable new device designs and higher device performance, thereby bringing the success of GaN electronics to a new level. This talk discusses our recent work on GaN MOS structures with interface trap density down to the ~ 1010 eV-1cm-2 range.

Contact vs. Non-Contact Cleaning: Correlating interfacial reaction mechanisms to processing methodologies for enhanced FEOL/BEOL post-CMP cleaning
life on Thursday April 15th UTC+2: 14h50 – 15h10 (No. 10.6)


Abstract: Advanced CMP-slurries need to meet very stringent specifications and involve an increasing number of additives. Therefore, it is essential to probe the slurry-particle substrate interactions in the presence of the liquid chemicals.
This talk will focus on the fundamental aspects of contact and non contact post CMP cleaning for FEOL and BEOL applications.
