Week In Review: Semiconductor Manufacturing, Test


Intel dropped out of a $5.4 billion deal to purchase Tower Semiconductor in Israel. Intel cited the inability to obtain regulatory approval in a timely manner as the reason for ending the deal signed in February. Intel will pay a $353 million termination fee to Tower. The silicon wafer supply has moved back into positive territory for 2023 thanks to a 7% decline in wafer shipments combined w... » read more

Max Planck Generates Up To 14 Entangled Photons In A Defined Way And With High Efficiency


A new technical paper titled "Efficient generation of entangled multiphoton graph states from a single atom" was published by researchers at Max Planck Institute of Quantum Optics. The team of physicists "generated up to 14 entangled photons in an optical resonator, which can be prepared into specific quantum physical states in a targeted and very efficient manner. The new method could facil... » read more

X-ray holography Using a technique called X-ray holography, a group of researchers have uncovered the phase transitions of vanadium dioxide. X-ray holography is a promising high-resolution metrology technique. Vanadium dioxide is one of many materials that can exhibit metal or insulator properties depending on the temperature. Vanadium dioxide can switch from an insulating to a metallic pha... » read more

Silicon photonics prototyping A group of European and other research organizations have put the finishing touches on a project to help propel the development of silicon photonics into the commercial market. The project, dubbed ESSenTIAL, enables small- to mid-sized enterprises to develop prototypes and products based on silicon photonics. Funded by the European Commission, the project inclu... » read more

Batman chips The demand for faster and higher-density storage has prompted researchers to look for ways to control the magnetic states of tiny magnets. Seeking to improve the magnetic recording speeds and spatial resolutions in structures, Radboud University and others attempted to switch the magnetization in microstructures by using a femtosecond laser pulse. The laser light did not switch... » read more

Direct-write diamond patterning Purdue University has devised a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns on a graphite substrate. The ability to pattern diamond surfaces could one day be used to make chips, biosensors and fuel cells. In the lab, researchers devised a multi-layered film, which includes a layer of graphite topped with a glass ... » read more
