A wafer looked a little like the discs used in CD players that had been common during childhood, but its actual purpose was to make semiconductor circuits.
The material that made up a wafer was silicon, which was extremely common in nature.
From the silicon dioxide that formed quartz to sand on the beach and even household glass, none could do without silicon.
However, obtaining electronic-grade silicon suitable for manufacturing chips required purifying the silicon.
The principle was simple: heat sand to separate out carbon monoxide and silicon, then repeat the process until ultrahigh-purity electronic-grade silicon was obtained, with more than nine digits after the decimal point.
This silicon purification process was called ingot casting in wafer processing. Once a high-purity silicon ingot had been cast, it would be cut to fixed specifications, then further ground and polished to produce wafers.
The reason Chen Jue had casually picked up a slab of concrete was that large amounts of sand were mixed in during concrete production. Sand was quartz, naturally occurring silicon dioxide.
Normally, extracting high-purity silicon from quartz-silicon dioxide-required heating and repeated purification to separate out the carbon monoxide and silicon.
But Chen Jue had already mastered the practically game-breaking ability of [Matter Interference]. He could extend his power down to the atomic level, so he did not need to use traditional heating and purification methods.
Golden energy spread from Chen Jue's five fingers, and the concrete in his palm began melting under the stimulation of the plasma energy, turning into a large blob of magma-like material.
As Chen Jue's mind energy penetrated it, a layer of pitch-black spots began appearing on the red-hot material in his palm.
These spots were unwanted impurities in the concrete, such as calcium carbonate, silicon dioxide, and so on.
Once these useless impurities
