Lithography Technology and Market Development: Leaders, Trends, and Application Prospects

Lithography technology plays a critical role in the field of semiconductor manufacturing. It involves projecting light onto a photosensitive material to form intricate circuit patterns. Common lithography techniques include electron beam lithography, X-ray lithography, and ultraviolet (UV) lithography. Among these, UV lithography is the most commonly used technology and holds about 90% market share in the semiconductor manufacturing industry.

ASML, a Dutch company, is the market leader in lithography machines, capturing over 70% of the global market share. Nikon and Canon also play important roles as lithography machine manufacturers, although their market shares are relatively smaller.

Lithography technology is advancing towards higher resolution and performance. Multiple patterning techniques, achieved through multiple exposures and different masks, enable higher resolution and complex structure fabrication. The market share of multiple patterning technology is expected to reach 26.4% by 2022. Another frontier technology is extreme ultraviolet (EUV) lithography, which utilizes extremely short wavelength light for projection, offering high resolution and patterning capabilities. The market share of EUV technology is projected to reach 22.7%.

Market demand drives the requirement for improved accuracy, speed, and reliability of lithography machines. The long-term growth in areas such as smartphones, Internet of Things (IoT), cloud computing, and artificial intelligence fuels the demand for high-performance, compact chips. The global semiconductor market reached approximately $580 billion in 2022 and is expected to further grow in 2023.

In addition to semiconductor manufacturing, lithography technology finds extensive applications in other fields. For example, it is utilized in biomedical applications for manufacturing biochips and microfluidic devices, as well as in optical device, flat panel display, and photonic integrated circuit domains.

The development of lithography technology faces challenges such as overcoming technological hurdles in next-generation processes, dealing with the complexity of multiple patterning techniques, and the commercialization and adoption difficulties of EUV technology. However, with the emergence of new semiconductor technologies, lithography technology will continue to play a crucial role. The demand for high-performance chips and the development of areas such as photonic integrated circuits, 3D-ICs, heterogeneous integration, and quantum computing create broader application prospects for lithography technology.

The importance of lithography technology in semiconductor manufacturing cannot be overstated. ASML, as the market leader, alongside Nikon and Canon, plays significant roles in this sector. Multiple patterning and EUV technologies are the current trends with increasing market share. The rapid development of smartphones, IoT, cloud computing, and artificial intelligence drives the demand for high-performance and compact chips. Furthermore, lithography technology holds vast application prospects in fields such as biomedical applications.
