SPIE, the international society for optics and photonics’ Post

I am honored to share with you this interview I conducted with Professor Emeritus Joseph Braat from the Optics Research group of TUDelft, published recently in Advanced Photonics #AdvancedPhotonics. Joseph was respected for his contribution to diffraction-limited optical imaging. In this interview, Joseph reviewed his career on the development of optical storage and lithography, as well as his transition from industry to academia. The evolution of optical storage technology, as seen by Joseph, was a fascinating journey. The intense IP war was crucial for business success. However, it's intriguing to note that this once-important technology vanished from the mainstream market just after 40 years, and it was not replaced by another storage technology, but by the advent of internet streaming! In Joseph's view, the unprecedented challenge for optical lithography is not just building one prototype but rather enabling the mass production of such efficient and accurate machines at an industrial scale. This requires intimate collaboration between scientists and engineers, as well as a practical and honest attitude in R&D. Like Joseph said: "The measured data will always force the adjustment of scientific models, not the other way around. This is how applied science works!" I hope Joseph's experiences and insights can inspire a broad spectrum of audiences. Please check the original article here 👇:

Recent work has revealed that graphene layers twisted relative to each other by a small ‘magic angle’ can act as perfect insulator or superconductor. But the physics of the electron-phonon interactions are a mystery. As part of a worldwide international collaboration, TU/e researcher Klaas-Jan Tielrooij has led a study on electron-phonon interactions in graphene layers. And they have made a startling discovery. #nanotechnology #graphene #materialsscience #2dmaterials #advancedmaterials #engineering #electronics #optics

Engaging with optical systems during experimental work to explore the novel physics of semiconductor devices is consistently gratifying. #researchanddevelopment #semiconductormanufacturing #semiconductor #academiclife #academicresearch #engineering #scienceandtechnology

The diamond in an engagement ring, the wonder-material graphene and the ‘lead’ in a humble pencil are all formed from carbon, but display profoundly different characteristics. Carbon materials such as these are among the most famous examples of how diverse properties can emerge in materials, based only on the rearrangement of the structure of atoms. #nanotechnology #materialsscience #electronics #engineering #innovation #simulation #scienceandtechnology #quantum #AI

As you may know, IMEC this year is organizing a conference in September which is focused on fundamental research of low energy electrons and their interaction with molecules and thin films towards applications for patterning and imaging.   Scope of the conference is primarily sharing the learning on the understanding of low-energy electrons interaction with the matter and stimulate collaboration among researchers and engineers to enable future patterning applications. Nowadays the increase of synergy between academia and semiconductor industry is becoming more and more important as it is important to create new opportunities and attract early-stage researchers to pursue their career in this field. In this context we hope to gather engineers, researchers and students which have interest in such a field to such a conference. To do so, we also applied an attractive registration fee.   I was wondering If you could consider and invite your researchers and students to attend such a conference. Details can be found on the website of the conference. https://lnkd.in/eF3FftHA   Looking forward to meet you in Leuven,  

The fabrication of semiconductor quantum wire and quantum dot arrays with high uniformity and controlled positioning is an outstanding challenge in nanostructure materials science. We demonstrate a significant step forward by combining self-organized epitaxial growth with lithographic patterning and the assistance of atomic hydrogen on high-index GaAs substrates. This concept provides a strict control of chemical, structural and geometric perfection of these semiconductor nanostructures which is needed for realistic device applications.

Let us draw your attention to a recent publication on 𝗨𝗦𝗣 𝗹𝗮𝘀𝗲𝗿 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗶𝗻𝗴 by the University of Applied Sciences Aschaffenburg, featuring the 𝗫𝗔𝗥𝗜𝗢𝗡 𝗢𝗽𝘁𝗶𝗰𝗮𝗹 𝗠𝗶𝗰𝗿𝗼𝗽𝗵𝗼𝗻𝗲 𝗘𝘁𝗮𝟰𝟱𝟬 𝗨𝗹𝘁𝗿𝗮. This research demonstrates the capabilities of our technology in monitoring micro-layer ablation on semiconductor components. Here are some key points: - Ultra-short-pulsed laser ablation of thin multilayer materials can be monitored using XARION’s Eta450 Ultra Optical Microphone. - Monitoring the material transition between polymer and copper during laser ablation is facilitated by observing a broad acoustic frequency spectrum between 100 kHz and 2 MHz in air, coupled with detecting a sudden change in acoustic energy. - A direct correlation was found between increased detected acoustic energy and a higher ablation rate.   We extend our appreciation to the team at TH Aschaffenburg University of Applied Sciences for their remarkable research, and we're honored to contribute to the advancement of real-time laser processing quality control. Stay tuned for further developments!   #XARION #THAschaffenburg #USPLaserProcessing #OpticalMicrophone #SemiconductorIndustry #Research #Innovation
