Introduction to Lithography and Its Importance
Lithography is a critical manufacturing process used in the fabrication of semiconductors, playing a vital role in the electronics industry. It involves the patterning of materials, enabling the production of intricate microstructures needed for various electronic components. At its core, lithography encompasses a series of steps that transfer a desired geometric pattern from a photomask to a light-sensitive chemical photoresist on the substrate, which is typically a silicon wafer. This technique is not only essential for producing traditional electronic circuits but also serves as the foundation for more advanced technologies, including AI chips, 5G systems, and quantum computing.
As the demand for smaller, more efficient chips continues to rise, advancements in lithographic techniques have become increasingly important. Innovations such as extreme ultraviolet (EUV) lithography have permitted the fabrication of transistors at unprecedented scales, significantly enhancing performance while reducing power consumption. This miniaturization is crucial for accommodating the growing complexity of AI algorithms and for supporting the higher data throughput requirements of 5G networks. Furthermore, as quantum computing technology evolves, precise lithographic processes are imperative for constructing qubit architectures that can function reliably at extremely small scales.
The role of lithography extends beyond just creating smaller features; it is about pushing the boundaries of what is technologically feasible. The advancements in lithographic processes empower semiconductor manufacturers to produce chips with greater functionality and efficiency, which are essential for achieving breakthroughs in AI, 5G, and quantum computing.

Each of these techniques plays a unique role in pushing the boundaries of technology and enhancing manufacturing capabilities.
Photolithography is the most extensively used technique in semiconductor fabrication. It employs light to transfer geometric patterns from a photomask onto a photosensitive substrate, typically silicon wafers. This process involves several steps, including coating the wafer with photoresist, exposing it to light through the photomask, and developing the image. The primary advantage of photolithography is its ability to produce intricate and precise patterns at relatively low costs. However, as the demand for smaller features in chips increases, limitations in resolution have become apparent.
In response to the challenges faced by traditional photolithography, extreme ultraviolet (EUV) lithography has emerged as a groundbreaking technology.
