Yield Management Embraces Expanding Role
By Laura Peters - 12 Nov, 2024 - Comments: 0

Competitive pressures, shrinking time-to-market windows, and increased customization are collectively changing the dynamics and demands for yield management systems, shifting left from the fab to the design flow and right to assembly, packaging, and in-field analysis. The basic role of yield management systems is still expediting new product introductions, reducing scrap, and delivering grea... » read more

Hybrid Bonding Makes Strides Toward Manufacturability
By Laura Peters - 28 Oct, 2024 - Comments: 0

Hybrid bonding is gaining traction in advanced packaging because it offers the shortest vertical connection between dies of similar or different functionalities, as well as better thermal, electrical and reliability results. Advantages include interconnect scaling to submicron pitches, high bandwidth, enhanced power efficiency, and better scaling relative to solder ball connections. But whil... » read more

Metrology Advances Step Up To Sub-2nm Device Node Needs
By Laura Peters - 15 Oct, 2024 - Comments: 0

Metrology and inspection are dealing with a slew of issues tied to 3D measurements, buried defects, and higher sensitivity as device features continue to shrink to 2nm and below. This is made even more challenging due to increasing pressure to ramp new processes more quickly. Metrology tool suppliers must exceed current needs by a process node or two to ensure solutions are ready to meet tig... » read more

Optimizing Wafer Edge Processes For Chip Stacking
By Laura Peters - 23 Sep, 2024 - Comments: 0

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

Defect Challenges Grow At The Wafer Edge
By Laura Peters - 10 Sep, 2024 - Comments: 0

Reducing defects on the wafer edge, bevel, and backside is becoming essential as the complexity of developing leading-edge chips continue to increase, and where a single flaw can have costly repercussions that span multiple processes and multi-chip packages. This is made more difficult by the widespread rollout of such processes as hybrid bonding, which require pristine surfaces, and the gro... » read more

Building Smarter, Better Fabs
By Laura Peters - 15 Aug, 2024 - Comments: 0

Battling labor shortages, faster ramp rates, and data overload, the process of designing and building greenfield fabs requires a combination of tech tools, failing earlier approaches and superior planning from day one. The complexity and scale of semiconductor fabs is skyrocketing as is the capital cost. Chipmakers are looking to ramp multibillion dollar fabs faster despite the hurdles of la... » read more

AI/ML’s Role In Design And Test Expands
By Laura Peters - 06 Aug, 2024 - Comments: 1

The role of AI and ML in test keeps growing, providing significant time and money savings that often exceed initial expectations. But it doesn't work in all cases, sometimes even disrupting well-tested process flows with questionable return on investment. One of the big attractions of AI is its ability to apply analytics to large data sets that are otherwise limited by human capabilities. In... » read more

Key Technologies To Extend EUV To 14 Angstroms
By Laura Peters - 29 Jul, 2024 - Comments: 2

The top three foundries plan to implement high-NA EUV lithography as early as 2025 for the 18 angstrom generation, but the replacement of single exposure high-NA (0.55) over double patterning with standard EUV (NA = 0.33) depends on whether it provides better results at a reasonable cost per wafer. So far, 2024 has been a banner year for high-numerical aperture EUV lithography. Intel Foundry... » read more

Digital Twins Find Their Footing In IC Manufacturing
By Laura Peters - 09 Jul, 2024 - Comments: 0

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

Controlling Warpage In Advanced Packages
By Laura Peters - 24 Jun, 2024 - Comments: 1

Warpage is becoming a serious concern in advanced packaging, where a heterogeneous mix of materials can cause uneven stress points during assembly and packaging, and under real workloads in the field. Warpage plays a critical role in determining whether an advanced package can be assembled successfully and meet long-term reliability targets. New advances, such as molding compounds with impro... » read more
