From Sand to Silicon: How a CPU Is Made Ever wonder how Intel makes a CPU? Here's a glimpse at some of the amazingly sophisticated work going on daily inside those cutting-edge fabrication plants.

Silicon ingot Multiple purification and filtering processes are performed in order to deliver electronic-grade silicon, which has a purity of 99.9999%. A purified silicon ingot, which weighs ...

Elemental silicon is very rare, though, and so getting appreciable amounts of the metalloid that’s pure enough to be useful requires some pretty energy- and resource-intensive mining and ...

Solar panels are mostly made of silicon, which derives from sand. Here's how that abundant substance is transformed into something that generates electricity.

Researchers at the Universities of Melbourne and Manchester have invented a breakthrough technique for manufacturing highly purified silicon that brings powerful quantum computers a big step closer.

San Jose, California — The Santa Clara Valley Water District is embarking on an effort to revamp the image of purified wastewater and lay the groundwork for replenishing local aquifers, reports ...

Synthetic gemstones, including ruby, sapphire, garnet, and spinel can be grown using the method. On the other hand, the method is far from the only way of making ingots of monocrystalline silicon.

Once the silicon has been purified to the required degree (something in the region of 99.9999999 per cent pure), it's formed into a single contiguous 100kg ingot of silicon.

Therefore, the resulting silicon chunks are again broken up, melted at 1450 degrees Celsius, grown using different methods and transferred into silicon ingots weighing 200 to over 1000 kilograms.
