Chapter Content
As CMOS transistors shrink in size, the complexity of the fabrication process increases, requiring more advanced manufacturing techniques, such as extreme ultraviolet (EUV) lithography.
Detailed Explanation
As technology progresses, CMOS transistors are being made smaller and smaller. This miniaturization creates challenges in the manufacturing process. When transistors shrink, the tools and techniques used to create them must also adapt to the smaller scales. One significant advancement in this area is extreme ultraviolet (EUV) lithography, which allows manufacturers to create finer patterns on the silicon wafers. This is crucial because smaller transistors can lead to more power-efficient and faster circuits, but they also require more precision in their fabrication to maintain reliability and performance.
Examples & Analogies
Think of building a LEGO structure. When you're working with large blocks, it's relatively easy to snap them together. But as you work with smaller and more intricate pieces, your construction requires more precise movements and specialized tools to fit them together correctly. Similarly, as transistors become smaller, the fabrication process requires more advanced techniques and tools to ensure that everything fits and functions as intended.
