Optimizing Wafer Edge Processes For Chip Stacking


Stacking chiplets vertically using short and direct wafer-to-wafer bonds can reduce signal delay to negligible levels, enabling smaller, thinner packages with faster memory/processor speeds and lower power consumption. The race is on to implement wafer stacking and die-to-wafer hybrid bonding, now considered essential for stacking logic and memory, 3D NAND, and possibly multi-layer DRAM stac... » read more

New Materials Are in High Demand


Materials suppliers are responding to the intense pressures to improve power, performance, scaling, and cost issues, which follows a long timeline from synthesis to development and high volume manufacturing in fabs. The advances in machine learning help present a wide field of candidates, which engineers then narrow to potential use. When building standard logic semiconductor chips, the prim... » read more

Chip Industry Week in Review


The Biden-Harris Administration announced preliminary terms with HP for $50 million in direct funding under the CHIPs and Science Act to support the expansion and modernization of HP’s existing microfluidics and microelectromechanical systems (“MEMS”) facility in Corvallis, Oregon. CHIPS for America launched the CHIPS Metrology Community, a collaborative initiative designed to advance ... » read more

Chip Industry Week in Review


Okinawa Institute of Science and Technology proposed a new EUV litho technology using only four reflective mirrors and a new method of illumination optics that it claims will use 1/10 the power and cost half as much as existing EUV technology from ASML. Applied Materials may not receive expected U.S. funding to build a $4 billion research facility in Sunnyvale, CA, due to internal government... » read more

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
