Global Silicon Wafer Shipments Projected to Log Robust Growth Through 2024, SEMI Reports

MILPITAS, Calif.  ─ Global silicon wafer shipments are projected to register robust growth through 2024, with wafer area increasing 13.9% year-over-year in 2021 to a record high of nearly 14,000 millions of square inches (MSI), SEMI reported today in its annual silicon shipments forecast for the semiconductor industry. The logic, foundry and memory sectors are contributing to the 2021 silicon shipment expansion.

SEMI logo“We are seeing a significant increase in silicon shipments driven by strong secular demand for semiconductors across multiple end markets,” said Inna Skvortsova, an Industry Research & Statistics market analyst at SEMI. “The growth momentum is expected to continue in the following years but could be tempered by the slowing pace of the macroeconomic recovery and timing of the wafer manufacturing capacity additions needed to meet growing demand.”

Silicon wafers are the fundamental building material for the majority of semiconductors, which are vital components of all electronics including computers, telecommunications products, and consumer devices. The highly engineered thin disks are produced in diameters of up to 12 inches and serve as the substrate material on which most semiconductor devices, or chips, are fabricated.

All data cited in this release is inclusive of polished silicon wafers and epitaxial silicon wafers shipped by wafer manufacturers to end users. The data does not include non-polished or reclaimed wafers.
