The Silicon Manufacturers Group is a special interest group of SEMI® members who produce polycrystalline silicon, silicon on insulator (SOI), mono-crystalline silicon or silicon wafers (e.g., as cut, polished, Epi, etc.). The Silicon Manufacturers Group acts as an independent special interest group within the SEMI structure, and is open to all SEMI members involved in manufacturing the silicon products listed above.

The purpose of the group is to facilitate collective efforts on issues relating to the silicon industry including the development of market information and statistics about the silicon industry and the semiconductor market. This information will help promote customer awareness of the technical and business issues facing the silicon industry in meeting the semiconductor industry expectations in product quality and value.

Silicon wafers are the fundamental building material for semiconductors, which in turn, are vital components of virtually all electronics goods, including computers, telecommunications products, and consumer electronics. The highly engineered thin round disks are produced in various diameters (from 1 inch to 12 inch) and serve as the substrate material on which most semiconductor devices or "chips" are fabricated.
