How To Compare Chips


Traditional metrics for semiconductors are becoming much less meaningful in the most advanced designs. The number of transistors packed into a square centimeter only matters if they can be utilized, and performance per watt is irrelevant if sufficient power cannot be delivered to all of the transistors. The consensus across the chip industry is that the cost per transistor is rising at each ... » read more

Technical Paper Roundup: Sept. 12


New technical papers added to Semiconductor Engineering’s library this week. [table id=51 /] Semiconductor Engineering is in the process of building this library of research papers. Please send suggestions (via comments section below) for what else you’d like us to incorporate. If you have research papers you are trying to promote, we will review them to see if they are a good fit f... » read more

Scaling Down To 2nm: Using Microwaves For Efficient & Stable Doping


A new technical paper titled "Efficient and stable activation by microwave annealing of nanosheet silicon doped with phosphorus above its solubility limit" was just published by researchers at National Taiwan University, Cornell University, TSMC, University of Valladolid, DSG Technologies, National Central University and National Yang Ming Chiao Tung University. A modified microwave was used... » read more

Week In Review: Manufacturing, Test


Some funding details are now available for the CHIPS Act in the U.S. The Biden Administration plans to spend the money in the following ways: $28 billion to establish domestic production of leading-edge logic and memory chips through grants, subsidized loans or loan guarantees; $10 billion to increase production of current-generation semiconductors and chips, and $11 billion for rese... » read more

Week In Review: Manufacturing, Test


New fab construction At an event in Arizona, U.S. Commerce Secretary Gina Raimondo urged states to compete for funding made available for producing semiconductors by the U.S. federal government. Indeed, several companies are already doing just that. The latest developments include: Micron plans to invest approximately $15 billion through 2030 for a new memory fab near its existing headquart... » read more

Week In Review: Manufacturing, Test


The U.S. Commerce Department issued export controls on key technologies, including gallium oxide (Ga2O3) and diamond substrates, which are used at high voltages and temperatures, as well as EDA tools specifically developed for GAA FETs. It's not clear how this will impact EDA companies, because many of the tools that will be used for designing for GAA FETs already are in use today for finFETs. ... » read more

Big Changes In Architectures, Transistors, Materials


Chipmakers are gearing up for fundamental changes in architectures, materials, and basic structures like transistors and interconnects. The net result will be more process steps, increased complexity for each of those steps, and rising costs across the board. At the leading-edge, finFETs will run out of steam somewhere after the 3nm (30 angstrom) node. The three foundries still working at th... » read more

Fan-Out Packaging Gets Competitive


Fan-out wafer-level packaging (FOWLP) is a key enabler in the industry shift from transistor scaling to system scaling and integration. The design fans out the chip interconnects through a redistribution layer instead of a substrate. Compared to flip-chip ball grid array (FCBGA) or wire bonds, it creates lower thermal resistance, a slimmer package, and potentially lower costs. Yet, if the h... » read more

Equipment Suppliers Brace For GaN Market Explosion


A huge GaN market is opening up, driven by consumer devices and the need for greater energy efficiency across many applications. Suppliers are ready, but to fully compete with SiC in high-voltage automotive applications will require further technological developments in power GaN (gallium nitride). Still, the 2020s mark a very high-growth phase for GaN markets. Revenues in the power GaN mark... » read more

New Uses For AI In Chips


Artificial intelligence is being deployed across a number of new applications, from improving performance and reducing power in a wide range of end devices to spotting irregularities in data movement for security reasons. While most people are familiar with using machine learning and deep learning to distinguish between cats and dogs, emerging applications show how this capability can be use... » read more
