China's share of US chip supply chain is larger than it appears, SIA report says

The Semiconductor Industry Association says China accounts for about 5 per cent of equipment and materials directly supplied to the US chip industry when measured by country of manufacture.

Its grip on certain rare earths needed for chipmaking exceeds 90 per cent, according to the report.

When measured by country of origin, the share of US chipmakers' roughly $27 billion in annual equipment and materials spending from US, European and Japanese suppliers falls from 95 per cent to 68 per cent.
