Context: ASML's new 'High NA EUV' machine, a groundbreaking semiconductor lithography device that costs $350 million and is crucial for creating the next generation of powerful computer chips. The machine uses extreme ultraviolet light and incredibly precise components to print intricate circuits on silicon wafers. It represents a significant technological advancement with strategic implications, as ASML is not allowed to sell these machines to China.
Semiconductor Lithography and ASML's Monopoly
- Semiconductor lithography is the science of printing intricate circuits with extreme precision on silicon wafers.
- ASML (Netherlands) has an absolute monopoly in the $125 billion semiconductor lithography machine market.
- It is the highest valued tech company in Europe.
'High NA EUV' Machine - A Technological Marvel
- ASML's new machine costs Rs 2,900 crore ($350 million) and is as big as a double-decker bus.
- It uses next-gen extreme ultraviolet (EUV) photolithography to make advanced semiconductors.
- Smallest feature size printable is governed by Rayleigh scattering criterion and is proportional to light wavelength.
- EUV light of 13.5 nm wavelength used, produced by firing lasers at tin droplets 50,000 times/second.
- Precision mirrors with atom-scale smoothness collect and reflect EUV light.
- Silicon wafer stage floats on magnetic field and position adjusted 20,000 times/sec with picometer accuracy.
Comparison with Previous Lithography Technologies
- Before EUV machines, chip-makers relied on deep UV light (193 nm wavelength).
- EUV lithography enables smaller feature sizes and higher transistor densities compared to previous technologies.
Importance of Transistor Density
- Increasing the number of transistors on a chip is the dominant way to make more powerful chips.
