Week In Review: Manufacturing, Test


Chipmakers and OEMs Samsung has announced its latest foldable smartphones--the Galaxy Z Fold3 5G and Galaxy Z Flip3 5G. The systems are based on Samsung’s 5nm application processor. One system is the company’s most affordable foldable phone. The Galaxy Z Fold3 is $1,799.99, while the Galaxy Z Flip3 is $999.99. Samsung also announced two smartwatches—the Galaxy Watch4 and Galaxy Watch4... » read more

Tailoring spatial entropy in EUV focused beams for multispectral ptychography


The Advanced Research Center for Nanolithography (ARCNL) and Vrije Universiteit Amsterdam have developed a new class of diffractive optical elements that paves the way towards more widespread use of EUV microscopy. Abstract "Diffractive optics can be used to accurately control optical wavefronts, even in situations where refractive components such as lenses are not available. For instance, c... » read more

Manufacturing Bits: July 20


Interference EUV lithography ESOL has developed a standalone interference extreme ultraviolet (EUV) lithography tool for use in R&D applications. The system, called EMiLE (EUV Micro-interference Lithography Equipment), is primary used to speed up the development of EUV photoresists and related wafer processes. The system is different than ASML’s EUV lithography scanners, which are ... » read more

Finding, Predicting EUV Stochastic Defects


Several vendors are rolling out next-generation inspection systems and software that locates problematic defects in chips caused by processes in extreme ultraviolet (EUV) lithography. Each defect detection technology involves various tradeoffs. But it’s imperative to use one or more of them in the fab. Ultimately, these so-called stochastic-induced defects caused by EUV can impact the perf... » read more

Demand, Lead Times Soar For 300mm Equipment


A surge in demand for various chips is causing select shortages and extended lead times for many types of 300mm semiconductor equipment, photomask tools, wafers, and other products. For the last several years, 200mm equipment has been in short supply in the market, but issues are now cropping up throughout the 300mm supply chain, as well. Traditionally, lead times have been three to six mont... » read more

Improvement Of EUV Si Hardmask Performance Through Wet Chemistry Functionalization


In EUV lithography, spin-on silicon hardmasks have been widely used not only as etch transfer layers, but also as assist layers to enhance the lithographic performance of resist. In this study, we demonstrate a novel approach to functionalize spin-on silicon hardmasks by hybridizing them with functional groups through a sol-gel approach. By varying the concentration and type of the functional g... » read more

What’s Next In Fab Tool Technologies?


Experts at the Table: Semiconductor Engineering sat down to discuss extreme ultraviolet (EUV) lithography and other next-generation fab technologies with Jerry Chen, head of global business development for manufacturing & industrials at Nvidia; David Fried, vice president of computational products at Lam Research; Mark Shirey, vice president of marketing and applications at KLA; and Aki Fuj... » read more

How Extensively Will Curvilinear ILT Be Used For EUV Photomasks?


Curvilinear shapes on photomasks lead to improved process windows, as the first installment of this blog series discussed. Our blog series continues with a video panel discussion of the benefits that curvilinear shapes have for EUV photomasks (masks) and whether curvilinear shapes will be used beyond today’s usage for hotspots. Our panellists approached the question of curvilinear ILT for ... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Several foundry vendors are building new fabs. The memory vendors, such as Samsung and SK Hynix, are also building new capacity. In another example, Taiwan DRAM supplier Nanya Technology plans to construct a new 300mm fab in the Taishan Nanlin Technology Park in New Taipei City. The plant will produce DRAMs with Nanya’s in-house developed 10nm-class process technologies a... » read more

Foundry Wars Begin


Leading-edge foundry vendors are gearing up for a new, high-stakes spending and technology race, setting the stage for a possible shakeup across the semiconductor manufacturing landscape. In March, Intel re-entered the foundry business, positioning itself against Samsung and TSMC at the leading edge, and against a multitude of foundries working at older nodes. Intel announced plans to build ... » read more
