How sand and Java are used to create the world’s most powerful chips
summary
Machines use a 40 kW laser amplifier to hit tin droplets at 70 m/s 50,000 times a second to produce EUV light; a single lithography system has ~450,000 parts, ships on 20 trucks plus three 747s and costs ≈$300M. Wafers are 30 cm across with ~564 dies, up to 140 million transistors/mm², and tools print up to 330 wafers per hour running 24/7. A Java-based iact platform with Apache Spark ingests ~31 TB/machine, tunes ~100,000 parameters, supports multi-language plugins, and uses deep learning to raise defect capture from ~70% to ~93% at production speed.
