A Forbidden Pitch Combination at Advanced Lithography Nodes

The current leading edge of advanced lithography nodes (e.g., “7nm” or “1Z nm”) features pitches (center-center distances between lines) in the range of 30-40 nm. Whether EUV (13.5 nm wavelength) or ArF (193 nm wavelength) lithography is used, one thing for certain is that the minimum imaged pitch … Read More

The Story of Ultrawideband SemiWiki 1

Over-engineered to perfection, outmaneuvered by Wi-Fi
In Part 1 of this series, we recounted the birth of wideband radio at the turn of the 20th century, and how superheterodyne radio killed wideband radios for messaging after 1920. But RADAR kept wideband research alive through World War 2 and the Cold War. Indeed, the story of… Read More

The Story of Ultra WideBand Part 1 SemiWiki

In the middle of the night of April 14, 1912, the R.M.S. Titanic sent a distress message. It had just hit an iceberg and was sinking. Even though broadcasting an emergency wireless signal is common today, this was cutting edge technology at the turn of the 20th century. This was made possible by the invention of a broadband radio developed… Read More

AI at the Edge

The potential for AI in cars, whether for driver assistance or full autonomy, has been trumpeted everywhere and continues to grow. Within the car we have vision, radar and ultrasonic sensors to detect obstacles in front, behind and to the side of the car. Outside the car, V2x promises to share real-time information between vehicles… Read More
