Transistors Reach Tipping Point At 3nm


The semiconductor industry is making its first major change in a new transistor type in more than a decade, moving toward a next-generation structure called gate-all-around (GAA) FETs. Although GAA transistors have yet to ship, many industry experts are wondering how long this technology will deliver — and what new architecture will take over from there. Barring major delays, today’s GAA... » read more

Design Challenges Increasing For Mixed-Die Packages


The entire semiconductor ecosystem is starting to tackle a long list of technology and business changes that will be needed to continue scaling beyond Moore's Law, making heterogeneous combinations of die easier, cheaper, and more predictable. There are a number of benefits to mixing die and putting them together in a modular way. From a design standpoint, this approach provides access to th... » read more

Next-Gen 3D Chip/Packaging Race Begins


The first wave of chips is hitting the market using a technology called hybrid bonding, setting the stage for a new and competitive era of 3D-based chip products and advanced packages. AMD is the first vendor to unveil chips using copper hybrid bonding, an advanced die-stacking technology that enables next-generation 3D-like devices and packages. Hybrid bonding stacks and connects chips usin... » read more

A New Dimension Of Complexity For IC Design


Full 3D designs involving logic-on-logic are still in the tire-kicking stage, but gaps in the tooling already are showing up. This is especially evident with static timing analysis (STA), which is used to validate a design’s timing performance by checking all possible paths for timing violations. STA issues began popping up particularly with the introduction of hybrid bonding, a bumpless p... » read more

Growth Spurred By Negatives


The success and health of the semiconductor industry is driven by the insatiable appetite for increasingly complex devices that impact every aspect of our lives. The number of design starts for the chips used in those devices drives the EDA industry. But at no point in history have there been as many market segments driving innovation as there are today. Moreover, there is no indication this... » read more

Advanced Packaging For Automotive Chips


Multiple types of chips may be better than one for dealing with large amounts and different types of data, but in automotive applications it's not entirely clear how or even whether they should be packaged together. The biggest problem with electronics in vehicles is the extreme range of temperatures, both within and outside of vehicles. Without adequate cooling, chips can age prematurely, s... » read more

A Broad Look Inside Advanced Packaging


Choon Lee, chief technology officer of JCET, sat down with Semiconductor Engineering to talk about the semiconductor market, Moore’s Law, chiplets, fan-out packaging, and manufacturing issues. What follows are excerpts of that discussion. SE: Where are we in the semiconductor cycle right now? Lee: If you look at 2020, it was around 10% growth in the overall semiconductor industry. ... » read more

More Errors, More Correction in Memories


As memory bit cells of any type become smaller, bit error rates increase due to lower margins and process variation. This can be dealt with using error correction to account for and correct bit errors, but as more sophisticated error-correction codes (ECC) are used, it requires more silicon area, which in turn drives up the cost. Given this trend, the looming question is whether the cost of ... » read more

What’s Missing For Designing Chips At The System Level


Semiconductor Engineering sat down to talk about design challenges in advanced packages and nodes with John Lee, vice president and general manager for semiconductors at Ansys; Shankar Krishnamoorthy, general manager of Synopsys' Design Group; Simon Burke, distinguished engineer at Xilinx; and Andrew Kahng, professor of CSE and ECE at UC San Diego. This discussion was held at the Ansys IDEAS co... » 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
