STORY: 3 scientists share 2023 Nobel Physics Prize DATELINE: Oct. 4, 2023 LENGTH: 00:02:15 LOCATION: Stockholm CATEGORY: SCIENCE SHOTLIST: 1. various of the press conference and photos of laureates of the 2023 Nobel Prize in Physics 2. various of the Royal Swedish Academy of Sciences STORYLINE: Three scientists, Pierre Agostini, Ferenc Krausz and Anne L'Huillier, won the 2023 Nobel Prize in Physics "for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter," the Royal Swedish Academy of Sciences announced here Tuesday. "The three Nobel Laureates in Physics 2023 are being recognized for their experiments, which have given humanity new tools for exploring the world of electrons inside atoms and molecules," the academy said in a statement. "The three scientists have demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy," it added.

TOKYO, Japan - File photo taken in August 2006 shows Japanese physicist Akira Tonomura. A fellow at electronics giant Hitachi Ltd. tipped as a future Nobel Prize winner for years, Tonomura died of pancreatic cancer early on May 2, 2012, at a hospital in Hidaka, Saitama Prefecture. He was 70. Tonomura was known for developing electron holography for observing microscopic structures in matter using the wave nature of electrons and confirming the so-called Aharonov-Bohm effect, the existence of which had long been disputed among physicists.

Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

The established technology will be used for dry etching, thin film formation and cleaning of silicon. Easy-to-handle gases such as argon and nitrogen are irradiated onto solid fluoropolymers to generate fluorine-containing gas. The gas is then used for plasma treatment. Using a proto device with electrodes developed for special equipment, the company irradiated nitrogen gas and etched a glass substrate, and was able to etch 40 nanometers in one minute. The company plans to achieve an etching speed of 200 nanometers for commercialization. Plasma is an unstable state in which electrons have been removed from molecules, and it modifies the surface of materials, improving adhesion and cleaning effects.

President Jun Sawada explains the IOWN concept at the NTTR&D Forum.

President Jun Sawada explains the IOWN concept at the NTTR&D Forum.

Jun Sawada, president of NTT, announced on April 13 that 65 companies are considering joining the "IOWN Global Forum" to be established with Intel and Sony in the spring of 2020. In addition to Microsoft, 55 of the companies are overseas, including Orange (France), Verizon (US), and China Telecom (Taiwan). Many global companies that support the IOWN concept of rapid processing of huge amounts of data by using light from communication networks to terminals are expected to join the list when it is established. In a speech in Tokyo on the same day, Sawada explained the reason why he proposed the IOWN concept. IOWN, which aims to be commercially available in 30 years, uses photons rather than electrons to transmit information between chips and cores within chips, making everything from networks to terminals optical, and realizing information processing capabilities that far exceed the limits of electrical control.
