What a wafer is made from.

The upstream of the upstream: silicon, gallium, germanium, indium and arsenic, as the U.S. Geological Survey printed them. Every January it publishes one summary per commodity covering the five years to date, and the overlapping years are not the same numbers as last year’s. Each edition is shown as it was printed.

What is here

Counted off the file, not typed.

30 editions across 5 commodities, holding 46 series and 205 restatements. Every figure is a work of the United States Government and is in the public domain.

A cell here is what the edition printed. Where the publisher printed a mark instead of a figure, the mark is shown as the mark, because a withheld number, a zero and a number nobody collected are three different facts and none of them is blank.

<25a range the publisher printed in place of a figure, which is a published value and not a withdrawal5

A range is not a withdrawal. USGS stopped printing an exact net import reliance and started printing a band. That is a published value in a coarser form, so it appears here as the band and is not counted as a figure the publisher took away.

Arsenic

6 editions, 2021 to 2026. metric tons, arseniccontent,unless otherwise specified.

A figure in bold is one the edition printed differently from the edition before it. A row appears once per edition that printed it, so a row that starts or stops partway down covers only the editions that carried it. Where the publisher renamed a row, both names are here, each over its own editions: deciding that two names mean one measurement is a judgement, and this record leaves it to the reader who can see both.

What this page will not tell you

The obvious next step, and why it is not taken.

It does not say why a figure moved. USGS restates a year as trade data settles and as an estimate becomes a measurement, and which of those happened in any one cell is not printed in the summary. The sequence is here and the reason is not invented.

It does not convert anything. A price in cents per pound stays in cents per pound, and a figure in thousand metric tons stays there.

It does not join these commodities to the fabs. Silicon metal becomes polysilicon and then a wafer, and gallium and arsenic become a compound semiconductor, but no publisher states how much of any of it reached which fab. The revisions page carries the same figures as a series over time.
