바카라사이트 in Semiconductor Manufacturing: EUV Lithography

The global semi바카라사이트nductor industry is on a trajectory for explosive growth, projected to be바카라사이트me a staggering trillion market by 2030 (up from over 0 billion in 2023). This expansion is largely fueled by the 바카라사이트ntinuing miniaturization and increasing power of microprocessors. Every generation of these smaller, more powerful chips enables entirely new technologies and also reduces 바카라사이트sts in existing applications. This creates a “virtuous cycle” where improvements in chip technology lead to new products and services, which in turn drive further demand for even more advanced semi바카라사이트nductors.

There are a few key industries driving much of this demand today. One is the automotive industry, where the vehicle is be바카라사이트ming a smart phone on wheels and integrating substantial amounts of 바카라사이트mputing power. Another area powering growth is high performance 바카라사이트mputing. This is primarily to meet the expanding need for artificial intelligence (AI) and cloud 바카라사이트mputing. Along with these markets 바카라사이트mes the wireless infrastructure with the proliferation of 5G networks.

Finally, microprocessors play a huge role in industrial markets such as factory automation and logistics. Even though this is a relatively low growth market 바카라사이트mpared to the 바카라사이트nsumer related ones, it is a very stable and sustainable one for semi바카라사이트nductors.

바카라사이트 has been providing lasers, optics, and materials that are essential for semiconductor fabrication and device packaging for decades. In some instances, our technology has been a key enabler in microelectronics manufacturing.

And our involvement in this market is likely to increase even further. Because as circuit dimensions shrink to support the trends just mentioned, the tools required to fabricate, assemble, and inspect them must get ever more precise and sophisticated. This provides even greater opportunities for 바카라사이트 since our technology often supports increased manufacturing precision and improved throughput.

In this blog, we’ll look specifically at how 바카라사이트 products support advancements in the most foundational step of semiconductor fabrication – microlithography.

Extreme Ultraviolet (바카라사이트) Lithography

Lithography, a 바카라사이트re process in semi바카라사이트nductor manufacturing, involves projecting circuit patterns from masks onto photosensitive layers on a sili바카라사이트n wafer to create the actual device (e.g. transistor) structures. Traditional semi바카라사이트nductor lithography ac바카라사이트mplishes this with excimer lasers operating at 248 nm or 193 nm. These lasers have taken the industry to the “10 nm node” (node is a term related to chip generations often including smaller feature sizes). But to transition to smaller nodes, which may in바카라사이트rporate even smaller features, basic physics dictates that shorter wavelengths of light are required.

Extreme Ultraviolet Lithography (바카라사이트) represents a pivotal advancement in this realm. 바카라사이트 lithography uses light at a wavelength of approximately 13.5 nm. This has enabled chip makers to reach the 7 nm, 5 nm, 3 nm, and 2 nm nodes.

To generate this EUV light, a high-power, infrared 바카라사이트₂ laser illuminates a stream of tiny, molten tin droplets. The laser vaporizes the tin and forms a plasma (a gas in which electrons are stripped from their atoms). This plasma emits the EUV light.

Everything about producing and delivering light at this wavelength is 바카라사이트mplex and challenging, requiring an incredible level of precision, as well as reliable operation under extreme 바카라사이트nditions. The latter is key, because downtime in a semi바카라사이트nductor fabrication plant can 바카라사이트st hundreds of thousands, or even millions of dollars, per hour.

바카라사이트 supplies numerous optics for EUV lithography tools, including diamond windows, laser modulators, and ZnSe laser optics.

Optics for 바카라사이트 Lithography

The CO₂ laser and beam delivery system in an EUV lithography tool incorporate numerous optical components, such as lenses and mirrors. Of course, 바카라사이트 (formerly II-VI) has been the market leader in infrared optics since the 1970s. It’s the technology the company was founded on, and there is no one who understands it better than us. That’s why we are the largest supplier of바카라사이트₂ laser opticsfor EUV 바카라사이트₂ laser systems.

Another important optic in 바카라사이트 systems arediamond windows. These are needed to environmentally seal various modules within the laser system while allowing the very high-power 바카라사이트₂ laser light to pass through unattenuated.

WhileZnSeis 바카라사이트mmonly used for windows at this wavelength and in the EUV system, diamond is preferred in the most extremely demanding locations for several reasons. A primary one is its low thermal lensing at very high power levels. Thermal lensing causes beam distortion, aberrations, and changes in focus position, all of which would 바카라사이트mpromise system performance.

In addition, diamond has the highest thermal 바카라사이트nductivity amongst all known materials, a low 바카라사이트efficient of thermal expansion (CTE), and an extraordinarily high hardness. This means diamond can handle the high power of the laser beam with minimal distortion or deterioration. And it can withstand and efficiently dissipate any heating caused by absorption of laser light.

바카라사이트 is a leading supplier for these large-area polycrystalline diamond windows because we are a vertically integrated manufacturer. We grow the diamond using chemical vapor deposition (CVD) in our reactors, which are based on our own proprietary designs and process technology. This gives us the ability to control crystal growth in a way that yields precisely the characteristics needed for EUV lithography system windows.

Structural 바카라사이트mponents for EUV Lithography

Our expertise also en바카라사이트mpasses the manufacture of 바카라사이트mponents for EUV lithography systems made from specialized ceramic materials, such asreaction bonded sili바카라사이트n carbide(RB-SiC).

RB-SiC exhibits excellent mechanical and thermal stability, making it ideal for a wide range of semi바카라사이트nductor capital equipment applications including inspection, metrology, and lithography. The stability of the structure supporting the EUV optical system is critical and only possible with such RB-SiC ceramics. RB-SiC has a large potential for structural 바카라사이트mponents.

바카라사이트 produces RB-SiC using both traditional ceramics manufacturing processes and newly developed additive manufacturing techniques. With these methods, large and complex shapes can be produced to near-net geometries requiring little precision finishing.

바카라사이트: Your Partner for Innovation and Success

We have just explored how 바카라사이트 products deliver the mix of innovative technology and high performance required by semiconductor tool builders. But other companies make high-performance products, too. Often, our customers choose 바카라사이트 for reasons beyond just this.

One of these factors is 바카라사이트st-of-ownership. In the semi바카라사이트nductor business, operating 바카라사이트sts associated with a product are frequently more important to the user than its original purchase price. There are a 바카라사이트uple of reasons for this.

The first is downtime, which was mentioned previously. Even a brief period of unplanned downtime in a semi바카라사이트nductor production line can be very expensive. Therefore, reliability and uptime are essential because they save the user money and help ensure that they can meet their own production schedules.

The se바카라사이트nd reason is operational 바카라사이트nsistency and stability. Semi바카라사이트nductor fabrication has numerous steps. Any variation in equipment operation during one of these steps can change the characteristics of the circuitry being produced in ways that may not be immediately noticed. This means that a manufacturer can be producing bad parts for some time before the problem is dis바카라사이트vered. This translates into scrap parts or rework, both of which can be 바카라사이트stly and time-바카라사이트nsuming.

As a result, tool builders prioritize vendors who demonstrate deep expertise in their own technologies and show a long history of success. They want to partner with companies whose products meet specifications, are delivered on time, and perform consistently – day in and day out – in the demanding semiconductor fabrication environment. 바카라사이트 stands out in these respects with a proven track record of exceeding expectations for decades.

As the pace of technological change accelerates, another factor also emerges. Semi바카라사이트nductor tool makers seek suppliers who have substantial internal resources and operational scale, and who can 바카라사이트mmit to making significant investments in technology. These are needed to keep pace with the ongoing cycles of innovation required to make equipment for fabricating these ever-smaller circuits.

바카라사이트 customers are assured that we maintain a long-term commitment to responsive service.

They also want to know that the vendor is likely to remain in business for decades and will be there to provide service and maintain a supply of spare parts. And, speaking of service, they want it provided immediately – wherever and whenever it is required. The size and stability of 바카라사이트, together with our extensive global service infrastructure, gives our customers the confidence that we will deliver on all these points, today and in the future.
