Optical #lithography is key to producing the #microchips found in most devices we use every day. So how does the process work? 🔽 🔦 The structures are imaged onto the wafer coated with a light-sensitive photoresist film. 🧽 The exposed parts are etched away. The free areas are filled with copper, and the wafer is polished. 🔄 A new silicon layer and photoresist film are applied, and the lithography process is repeated up to 100 times. ✂️ The processed wafer contains several thousand semiconductor chips, which are separated by micrometer-thin saw blades. Progressively finer chip structures are needed to make microchips that are even smaller, more powerful and more energy efficient. This can only be achieved with increasingly shorter wavelengths and increasingly accurate components. That’s why ZEISS Semiconductor Manufacturing Technology and its strategic partner ASML produce even more advanced optical lithography systems that use extreme ultraviolet light: EUV and High-NA-EUV lithography.

Single Vs. Multi-Patterning Advancements For #EUV EUV patterning has come a long way in the past five years, but old challenges resurface with high-NA EUV 💡 As #semiconductor devices become more complex, so do the methods for patterning them. Ever-smaller features at each new node require continuous advancements in #photolithography techniques and #technologies. While the basic #lithography process hasn’t changed since the founding of the industry — exposing light through a reticle onto a prepared silicon #wafer — the techniques and technology of every part of that process have changed dramatically. These advancements have accelerated over the past five years as extreme ultraviolet (EUV) lithography transitioned from the lab into high-volume production at 7nm and 5nm. Now, with high-numerical-aperture (high-NA) EUV on the horizon, the debate between single patterning and multi-patterning techniques for 3nm nodes and below has intensified. “EUV multi-patterning #lithography has been unique in that decisions about whether to use single- or multi-patterning have needed to consider the required dose to expose a wafer and still be manufacturable,” says Kevin Lucas, senior architect for mask solutions at Synopsys Inc. “A single-patterning lithography process may be more expensive than a double-patterning process, as single patterning may require more than twice the exposure dose, and have worse throughput on a very expensive scanner than a double-patterning process.” Thanks again to Gregory Haley and Semiconductor Engineering for the full article with more background and insights via the link below 💡🙏👇 https://lnkd.in/evfsbGHu #semiconductorindustry #semiconductors #semiconductor #technology #tech #foundry #innvovation #semiconductormanufacturing #computer #chip #chips #ic #icdesign #asml #netherlands #taiwan #usa #geopolitic
