Study Notes
Procuring Raw Materials
- Raw wafer is the main material needed to start production, represented as SLSI (Slice Silicon) in SAP.
- Raw wafers are categorized by size, such as 6-inch, 8-inch, 12-inch wafers, etc.
- A standard raw wafer batch consists of 25 wafers.
Production at FE Plants
- FE plants perform diffusion and wafer test production steps.
- These plants consume SLSI materials and produce SLDI (slice diffused) or CEPT (circuit element pre-tested) materials.
- SAP system setup is designed for Process Industry.
Production at BE Plants
- BE plants perform assembly and final test production steps.
- These plants consume CEPT materials and produce PEP (packed end product) materials.
- PEP materials are the final products, which are then handled for commercial sales.
Learn about the production process of semiconductors, including procuring raw materials and production at FE plants. Understand the role of SAP system in managing the process.
