New Interconnect Metals Need New Dielectrics


Just as circuit metallization must evolve to manage resistance as features shrink, so must the dielectric half of the interconnect stack. For quite some time, manufacturers have needed a dielectric constant (k) less than 4, which is the value for SiO2, but they have struggled to find materials that combine a low dielectric constant with mechanical and chemical stability. In work presented at... » read more

Chip Industry Week In Review


The U.S. Department of Commerce issued a notice of intent  to fund new R&D activities to establish and accelerate domestic advanced packaging capacity. CHIPS for America expects to award up to $1.6 billion in funding innovation across five R&D areas, as outlined in the vision for the National Advanced Packaging Manufacturing Program (NAPMP), with about $150 million per award in each... » read more

Digital Twins Find Their Footing In IC Manufacturing


Momentum is building for digital twins in semiconductor manufacturing, tying together the various processes and steps to improve efficiency and quality, and to enable more flexibility in the fab and assembly house. The movement toward digital twins opens up a slew of opportunities, from building and equipping new fabs faster to speeding yield ramps by reducing the number of silicon-based tes... » read more

Chip Industry Week In Review


JEDEC and the Open Compute Project rolled out a new set of guidelines for standardizing chiplet characterization details, such as thermal properties, physical and mechanical requirements, and behavior specs. Those details have been a sticking point for commercial chiplets, because without them it's not possible to choose the best chiplet for a particular application or workload. The guidelines ... » read more

SK hynix and TSMC plan to collaborate on HBM4 development and next-generation packaging technology, with plans to mass produce HBM4 chips in 2026. The agreement is an early indicator for just how competitive, and potentially lucrative, the HBM market is becoming. SK hynix said the collaboration will enable breakthroughs in memory performance with increased density of the memory controller at t... » read more

What Works Best For Chiplets


The semiconductor industry is preparing for the migration from proprietary chiplet-based systems to a more open chiplet ecosystem, in which chiplets fabricated by different companies of various technologies and device nodes can be integrated in a single package with acceptable yield. To make this work as expected, the chip industry will have to solve a variety of well-documented technical an... » read more

Memristor Crossbar Architecture for Encryption, Decryption and More


A new technical paper titled "Tunable stochastic memristors for energy-efficient encryption and computing" was published by researchers at Seoul National University, Sandia National Laboratories, Texas A&M University and Applied Materials. Abstract "Information security and computing, two critical technological challenges for post-digital computation, pose opposing requirement... » read more

Applied Materials may scale back or cancel its $4 billion new Silicon Valley R&D facility in light of the U.S. government's recent announcement to reduce funding for construction, modernization, or expansion of semiconductor research and development (R&D) facilities in the United States, according to the San Francisco Chronicle. TSMC could receive up to $6.6 billion in direct funding... » read more

Digital Twins Target IC Tool And Fab Efficiency


Digital twins have emerged as the hot "new" semiconductor manufacturing technology, enabling fabs to create a virtual representation of a physical system on which to experiment and optimize what's going on inside the real fab. While digital twin technology has been in use for some time in other industries, its use has been limited in semiconductor manufacturing. What's changing is the breadt... » read more
