Destructive Physical Analysis (DPA) in Semiconductors
In semiconductor failure analysis (FA), investigations typically begin with techniques that preserve the integrity of the sample while allowing analysts to develop initial hypotheses. However, when non-destructive methods cannot resolve structural uncertainty or verify internal construction, destructive physical analysis (DPA) may be required. Non-destructive approaches provide valuable information but do not always resolve the underlying […]

Laser-Based 3D Printing Could Build Future Bases on the Moon Researchers transform lunar rocks into durable building blocks
Through the Artemis Program, NASA hopes to establish a permanent human presence on the Moon in its southern polar region. China, Russia, and the European Space Agency (ESA) have similar plans, all of which involve building bases near the permanently shadowed regions (PSRs)—craters that contain water ice—that dot the South Pole-Aitken Basin. For these and other agencies, it is vital that these bases be […]
