IoT Security: Confusing And Fragmented


Security regulations for Internet-of-Things (IoT) devices are evolving around the world, but there is no consistent set of requirements that can be applied globally — and there may never be. What exists today is a patchwork of certification labs and logos. That makes it difficult for IoT-device designers to know where to get their security blessed. Unlike in data centers, where there is a ... » read more

Week In Review: Auto, Security, Pervasive Computing


Automotive Cadence will be capturing design insights from Presto Engineering, an ASIC designer working on high-performance system-in-package (SiP) development for the automotive and Industrial IoT markets. Presto, which also provides semiconductor services such as test and qualification, will use Cadence’s EDA and analysis tools (Allegro X Package Designer Plus, Clarity 3D Solver, Sigrity Xt... » read more

Power/Performance Bits: June 15


Low-loss photonic IC Researchers at EPFL built a photonic integrated circuit with ultra-low loss. The team focused on silicon nitride (Si3N4), which has orders of magnitude lower optical loss compared to silicon. It is used in low-loss applications such as narrow-linewidth lasers, photonic delay lines, and nonlinear photonics. In applying the material to photonic ICs, they took advantage... » read more

Measuring Moon dust The National Institute of Standards and Technology (NIST) and others have developed a new way to study and measure moon dust. Using an X-ray nano computed tomography (XCT) technique, researchers measured the 3D shapes of lunar particles as small as 400nm in length. The goal is to find out how these shapes impact the optical scattering characteristics of lunar dust on the... » read more

Going Vertical With GaN Devices


Gallium nitride has long been on the horizon for a variety of uses in semiconductors, but implementing this on a commercial scale has been relatively slow due to a variety of technical hurdles. That may be about to change. The wide bandgap of GaN makes it particularly attractive material for power conversion applications. Still, actually realizing its benefits in commercial devices has been ... » read more

Manufacturing Bits: March 23


Measuring acceleration The National Institute of Standards and Technology (NIST) has developed a new and better way to measure acceleration. NIST has developed an optomechanical accelerometer, a technology that has more resolution and bandwidth than conventional accelerometers. Optomechanical accelerometers uses laser light of a known frequency to measure acceleration. With the technology, ... » read more

Chasing After Carbon Nanotube FETs


Carbon nanotube transistors are finally making progress for potential use in advanced logic chips after nearly a quarter century in R&D. The question now is whether they will move out of the lab and into the fab. Several government agencies, companies, foundries, and universities over the years have been developing, and are now making advancements with carbon nanotube field-effect transi... » read more

The Chip Industry’s Next-Gen Roadmap


Todd Younkin, the new president and chief executive of the Semiconductor Research Corp. (SRC), sat down with Semiconductor Engineering to talk about engineering careers, R&D trends and what’s ahead for chip technologies over the next decade. What follows are excerpts of that conversation. SE: As a U.S.-based chip consortium, what is SRC's charter? Younkin: The Semiconductor Research... » read more

Manufacturing Bits: Jan. 11


3D printing with liquids Martin Luther University Halle-Wittenberg (MLU) has developed a way to combine both materials and liquids in 3D printing applications. Researchers from MLU have developed liquid‐filled capsules using 3D printing technology. This in turn enables new medical agents to be incorporated into pharmaceutical products. It also allows liquids to be integrated into material... » read more
