Are you interested in metrology systems? Laura María P.alacios-Narvaez and Dr Martin Herms, both Scientists in the PVA TePla Group are taking part in this year's international conference #GADEST2024 ‘Gettering and Defect Engineering in Semiconductor Technology’. Two papers will be presented on the application of the SIRD photo-elastic measurement system to innovative semiconductor materials for #microelectronics and #optoelectronics. 📅 Date: 8-13 September 2024 📍 Location: Bad Schandau (Germany) The SIRD optical measurement method enables companies in the semiconductor industry to analyse wafers made of various materials such as #Si, #SiC #GaAs or, more recently, #AlN. Defects in the material can be detected early, thus saving costs during production and guaranteeing high quality. Experts from PVA Metrology & Plasma Solutions GmbH will be presenting the possibilities of this technology at this year's international conference in Bad Schandau. #pvatepla #metrology #SIRD

✨✨✨ Ultrasensitive Silicon Photonic Refractive Index Sensor Based on Hybrid Double Slot Subwavelength Grating Microring Resonator 🧑🔬 Kaiwei Lu, Beiju Huang *, Xiaoqing Lv, Zan Zhang, Zhengtai Ma 🏫 Chinese Academy of Sciences, University of Chinese Academy of Sciences, Suzhou Institute of Microelectronics and Optoelectronics Integration, Chang'an University 🚩 Silicon photonic-based refractive #index #sensors are of great value in the detection of gases, biological and chemical substances. Among them, microring resonators are the most promising due to their compact size and narrow Lorentzian-shaped spectrum. The electric field in a subwavelength grating waveguide (#SWG) is essentially confined in the low-refractive index dielectric, favoring enhanced analyte-photon interactions, which represents higher sensitivity. However, it is very challenging to further significantly improve the sensitivity of SWG ring #resonator refractive index sensors. Here, a hybrid waveguide blocks double slot subwavelength grating microring resonator (#HDSSWG-MRR) refractive index sensor operating in a water refractive index environment is proposed. By designing a new waveguide structure, a sensitivity of up to 1005 nm/RIU has been achieved, which is 182 nm/RIU higher than the currently highest sensitivity silicon photonic micro ring refractive index sensor. Meanwhile, utilizing a unique waveguide structure, a Q of 22,429 was achieved and a low limit of detection of 6.86 × 10−5 RIU was calculated. https://lnkd.in/eNFX4W9B
