Summary:To filter out infrared light from the driving light source in the extreme ultraviolet lithography (EUVL) light source system, a rectangular grating structure needs to be fabricated on the surface of the collection mirror. However, the collection mirror grating usually undergoes deformation during the manufacturing process, resulting in a decrease in filtering efficiency. The process errors of grating height and upper base angle need to be...

On March 28th, Marvel Fusion, a laser fusion company from Munich, Germany, announced the completion of a B+round financing of 50 million euros, bringing the total amount of this round of financing to 113 million euros. It is reported that the company's cumulative financing has reached 385 million euros, making it the largest fusion company in Europe in terms of financing scale. This capital increase has attracted new investments from EQT Ventur...

On March 14, 2000, Trumpf established its first company in China - Trumpf Metal Sheet Products Co., Ltd., headquartered in Taicang, 50 kilometers northwest of Shanghai. Nowadays, Taicang has become a global strategic stronghold for the company. 25 years ago, this production base was originally used to demonstrate sheet metal processing production for Chinese enterprises. In the seventh year after the success of this move, "Trumpf Machine Tool C...

Researchers from the University of Aveiro in Portugal and the School of Engineering at Porto Institute of Technology (ISEP) in Portugal reported a study on the influence of laser beam intensity distribution on the geometric shape and process stability of lock holes under green laser radiation. The relevant paper titled "Influence of Laser Beam Intensity Distribution on Keyhole Geometry and Process Stability Using Green Laser Radiation" was publis...

In view of the reconstruction problem of stack imaging technology in noisy environment, Lin Nan's team from Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences, proposed an innovative method ProPtyNet based on unsupervised physical neural network, which is expected to be applied to chip CD measurement and defect detection. The article was published in Optics and lasers in engineering under the title of "Noise robust photograph...

Rocket Lab USA continues its path of vertical integration and has signed an exclusive but non binding agreement with MynaricAG, a German laser communication terminal (LCT) supplier and Rocket Lab supplier, to acquire the company for $75 million in cash or stock.If Mynaric achieves its revenue target, it will pay an additional revenue of up to $75 million. This acquisition depends on whether Mynaric can exit the Chapter 11 restructuring process ...

Recently, the research team of the High Power Laser Physics Joint Laboratory at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made significant progress in the study of single shot characterization technology for complex combination laser pulses. The research team utilized an improved broadband transient grating frequency resolved optical switch technology (TG-FROG) to achieve complete characterization of co...

The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power will increase by a hundred times - when lasers are...
