素材にとっての重要性
Modern logic uses about two-thirds of the stable elements somewhere in its process flow. Purity, not tonnage, is the constraint: parts per billion matter, and only a handful of suppliers on Earth can hold that specification.

Copper
The reddish metal that carries electricity better than anything except silver, and which humans have been smelting…
Gallium
A silvery metal that melts in your hand, and the basis of the compound semiconductors in fast chargers, radar and…
Hafnium
Zirconium's chemical shadow — always found with it, almost impossible to separate from it, and the opposite of it in…
High-Purity Quartz
Quartz sand so free of other elements that it can be melted into the crucible a silicon crystal is grown inside.
Silicon
The second-most-common element in the Earth's crust — ordinary sand — purified until only one atom in a billion is…
Tungsten
The metal with the highest melting point of them all — you can heat it to 3,400 C before it turns liquid.
