Semiconductor Materials

Silicon Si · 14

The second-most-common element in the Earth's crust — ordinary sand — purified until only one atom in a billion is something else.

What is it?

The second-most-common element in the Earth's crust — ordinary sand — purified until only one atom in a billion is something else.

Why does it matter?

Every chip and almost every solar panel starts as a single silicon crystal. The purification, not the raw material, is the hard part.

Deeper written sections for this material have not been published yet. Everything below is drawn straight from the source datasets and is complete.

Read the numbers correctly. USGS silicon figures are silicon CONTENT of ferrosilicon plus silicon metal, not polysilicon. Metallurgical-grade silicon (~99%), then polysilicon (99.9999999%), then a grown ingot, then wafers.

Where it comes from in the rock

All ore minerals →

These are the minerals that actually carry silicon. A deposit is only an orebody if one of them is concentrated enough to pay for digging it up.

Who produces it

See it on a map →
More than one series is published for this material. The USGS reports these separately because they measure different things — mine output and refinery output, or different chemical bases. They are shown as separate tables and must never be added together.

“Withheld” means the USGS suppressed the figure to avoid disclosing an individual company's data — it does not mean zero. Country rows do not always sum to the world total because the source rounds each figure independently and does not always break out an “other countries” line.

How much of it a technology needs

“Intensity” just means how much material one unit of something contains. These are indicative ranges — real designs vary by maker and model year, and every one of them is falling as engineers learn to use less.
TechnologyQuantity QuotedBasis
Crystalline Silicon Solar Module 2,500–4,000 kg per MW of capacityPolysilicon in the wafers
Gallium Nitride Power Device trace per deviceCommon substrate for GaN-on-Si
Leading-Edge Logic Chip 0.12–0.15 kg per 300 mm waferOne 300 mm wafer weighs about 125 g
