Global spending on equipment for 300mm wafer fabs (facilities that process 300-millimeter silicon wafers, the industry's mainstream size) will reach $227 billion by 2029, according to SEMI, the semiconductor industry association that tracks fab investment worldwide.

The figure lands as chipmakers push ahead with capacity programs on multiple continents. SEMI's fab-equipment tracking covers the tools that make chips — lithography, deposition, etch — rather than the buildings housing them.

What does the forecast mean for the supply chain?

The $227 billion mark points to sustained, not speculative, investment. Equipment makers, materials suppliers and fab construction firms can plan against a rising baseline through 2029. Governments in the US, Europe and Asia continue to underwrite new plants, and SEMI's projection reflects those commitments moving from announcement to tool orders.

For equipment vendors, the number translates directly into backlog. For chip buyers, it signals capacity arriving over several years — relief, but not immediate.

Why 300mm matters

300mm wafers remain the workhorse of advanced and mature-node production alike. Nearly all leading-edge logic, memory and power semiconductors run on the format. Spending concentrated there signals investment aimed at both AI-driven advanced chips and the mature-node devices that anchor automotive and industrial supply chains.

The takeaway

A $227 billion cumulative horizon through 2029 marks one of the strongest equipment cycles SEMI has projected. Watch quarterly billings reports for confirmation — forecasts get revised both ways. But the direction is clear: the industry is building, and paying equipment makers to do it at record scale.
