Partitioning For Better Performance And Power


Partitioning is becoming more critical and much more complex as design teams balance different ways to optimize performance and power, shifting their focus from a single chip to a package or system involving multiple chips with very specific tasks. Approaches to design partitioning have changed over the years, most recently because processor clock speeds have hit a wall while the amount of d... » read more

3D Printing For More Circuits


After several years of experimentation, and growing success in volume manufacturing for some use cases, technologies for 3D printing of electronic circuits are becoming more common. Some innovations in processes and materials are moving these technologies closer to mainstream electronics manufacturing. Christopher Tuck, professor of material science at the University of Nottingham, observed ... » read more

Scaling Bump Pitches In Advanced Packaging


Interconnects for advanced packaging are at a crossroads as an assortment of new package types are pushing further into the mainstream, with some vendors opting to extend the traditional bump approaches while others roll out new ones to replace them. The goal in all cases is to ensure signal integrity between components in IC packages as the volume of data being processed increases. But as d... » read more

HBM3: Big Impact On Chip Design


An insatiable demand for bandwidth in everything from high-performance computing to AI training, gaming, and automotive applications is fueling the development of the next generation of high-bandwidth memory. HBM3 will bring a 2X bump in bandwidth and capacity per stack, as well as some other benefits. What was once considered a "slow and wide" memory technology to reduce signal traffic dela... » read more

Architecting Interposers


An interposer performs a similar function as a printed circuit board (PCB), but when the interposer is moved inside a package the impact is significant. Neither legacy PCB nor IC design tools can fully perform the necessary design and analysis tasks. But perhaps even more important, adding an interposer to a design may require organizational changes. Today, leading-edge companies have shown ... » read more

HBM3 Memory: Break Through To Greater Bandwidth


AI/ML’s demands for greater bandwidth are insatiable driving rapid improvements in every aspect of computing hardware and software. HBM memory is the ideal solution for the high bandwidth requirements of AI/ML training, but it entails additional design considerations given its 2.5D architecture. Now we’re on the verge of a new generation of HBM that will raise memory and capacity to new hei... » read more

Fan-Out And Packaging Challenges


Semiconductor Engineering sat down to discuss various IC packaging technologies, wafer-level and panel-level approaches, and the need for new materials with William Chen, a fellow at ASE; Michael Kelly, vice president of advanced packaging development and integration at Amkor; Richard Otte, president and CEO of Promex, the parent company of QP Technologies; Michael Liu, senior director of globa... » read more

Can We Efficiently Automate 2.5/3D IC ESD Protection Verification?


Protection against ESD events (commonly referred to as ESD robustness) is an extremely important aspect of integrated circuit (IC) design and verification, including 2.5/3D designs. ESD events cause severe damage to ICs due to a sudden and unexpected flow of electrical current between two electrically charged objects. This current may be caused by contact, an electrical short, or dielectric bre... » read more

Automated ESD Protection Verification For 2.5D And 3D ICs


While automated flows for ESD protection verification are well-established for 2D ICs, 2.5D and 3D designs present new challenges in both ESD circuit design and verification. Advanced automated ESD verification methodology accurately and effectively evaluates ESD protection in 2.5/3D IC designs. Ensuring correct and consistent ESD protection in 2.5/3D ICs raises the reliability and product life... » read more

Data Tsunami Pushes Boundaries Of IC Interconnects


Rapid increases in machine-generated data are fueling demand for higher-performance multi-core computing, forcing design teams to rethink the movement of data on-chip, off-chip, and between chips in a package. In the past, this was largely handled by the on-chip interconnects, which often were a secondary consideration in the design. But with the rising volumes of data in markets ranging fro... » read more
