NAND Flash Targets 1,000 Layers


The chip industry is pushing to quadruple the stack height of 3D NAND flash from 200 layers to 800 layers or more over the next few years, using the additional capacity will help to feed the unending need for more memory of all types. Those additional layers will add new reliability issues a number of incremental reliability challenges, but the NAND flash industry has been steadily increasin... » read more

HBM Options Increase As AI Demand Soars


High-bandwidth memory (HBM) sales are spiking as the amount of data that needs to be processed quickly by state-of-the-art AI accelerators, graphic processing units, and high-performance computing applications continues to explode. HBM inventories are sold out, driven by massive efforts and investments in developing and improving large language models such as ChatGPT. HBM is the memory of ch... » read more

Using Dummy Patterning To Solve Etch Uniformity Problems


Semiconductor devices are made up of hundreds of thin layers of materials stacked by multiple deposition and etch processes. Process engineers need to design the best combination of deposition and etch processes to ensure uniformity across an entire chip area and across the silicon wafer. Uniformity is the most common and critical parameter that is monitored in semiconductor fabrication, especi... » read more

FOPLP Gains Traction in Advanced Semiconductor Packaging


Fan-Out Panel-Level Packaging (FOPLP) for advanced nodes, once hindered by manufacturability and yield challenges, is emerging as a promising solution to meet the industry’s demands for higher integration densities and cost efficiency. Traditionally, FOPLP has been a go-to solution for cost-sensitive applications in consumer electronics, IoT devices, and mid-tier automotive systems. Its ab... » read more

One Chip Vs. Many Chiplets


Experts at the Table: Semiconductor Engineering sat down to discuss the growing list of challenges at advanced nodes and in advanced packages, with Jamie Schaeffer, vice president of product management at GlobalFoundries; Dechao Guo, director of advanced logic technology R&D at IBM; Dave Thompson, vice president at Intel; Mustafa Badaroglu, principal engineer at Qualcomm; and Thomas Ponnusw... » read more

Asia Government Funding Surges


Billions of dollars have been pouring into Asian countries for the past few years in an effort to boost their production capacity, explore leading-edge technology, compete on the global stage, and shore up supply chains in the face of geopolitical turmoil. Each country has its own plan to maintain a foothold in the global market, from China’s Big Fund to Korea’s Yongin Cluster and Japan�... » read more

Chip Industry Week In Review


Europe's top court ruled in Intel's favor, voiding a $1.1 billion fine imposed by the European Union and dismissing charges of anti-competitive behavior. IBM released yield benchmarks for high-NA EUV, which serve as proof points that the newest advanced litho equipment will enable scaling beyond the 2nm process node. Also on the lithography front, Nikon is developing a maskless digital litho... » read more

Metal-Oxide-Metal Capacitor Simulation And Modeling By Virtual Fabrication


Metal-Oxide-Metal (MOM) capacitors are passive radio frequency (RF) capacitive devices that are a common component in semiconductor logic chips [1]. A SPICE model of a MOM capacitor is typically used by designers during the design and performance evaluation of logic chip RF circuitry. Traditionally, it may take at least 3 months from the completion of the design layout, wafer fabrication, final... » read more

Advanced Packaging Driving New Collaboration Across Supply Chain


The semiconductor industry is undergoing a profound shift in packaging technologies to ones that rely on close collaboration among multiple stakeholders to solve intricate, multi-faceted, and extraordinarily complex problems. At the heart of this change is the convergence of heterogeneous integration, chiplets, and 3D stacking. Heterogeneous approaches allow companies to combine different te... » read more

Monolithic Vs. Heterogeneous Integration


Experts at the Table: Semiconductor Engineering sat down to discuss two very different paths forward for semiconductors and what's needed for each, with Jamie Schaeffer, vice president of product management at GlobalFoundries; Dechao Guo, director of advanced logic technology R&D at IBM; Dave Thompson, vice president at Intel; Mustafa Badaroglu, principal engineer at Qualcomm; and Thomas Po... » read more
