What resistivity values can be selected for this 2-inch N-type <111> single-side polished silicon wafer?
The wafer offers selectable resistivity values: 0.001-0.005 ohm.cm, 1-10 ohm.cm, >10 ohm.cm, >5K ohm.cm, and >10K ohm.cm.
Is this wafer available in both Czochralski (CZ) and Float Zone (FZ) growth methods?
Yes, the product description states that 6N monocrystalline silicon CZ/FZ material is available for this wafer configuration.
What are the flatness specifications (TTV, BOW, WARP) for this 2-inch silicon wafer?
The wafer has a total thickness variation (TTV) of less than 5 µm, bow of less than 10 µm, and warp of less than 10 µm.
This 2-inch N-type <111> monocrystalline silicon wafer (single-side polished) offers 6N purity and tight geometric tolerances (TTV <5 µm, BOW <10 µm, WARP <10 µm, Ra <0.5 nm), making it suitable for research and prototyping applications. The single-side polished finish with etched back side and small diameter are key operational considerations.
Positive
- High purity 6N silicon: The wafer is fabricated from 6N (99.9999%) monocrystalline silicon using CZ or FZ methods, ensuring low defect density and consistent electronic properties suitable for advanced research and device prototyping.
- Tight geometric tolerances: With TTV <5 µm, BOW <10 µm, WARP <10 µm, and front-side roughness Ra <0.5 nm, the wafer provides excellent flatness and surface quality critical for lithography and thin-film deposition processes.
Trade-offs
- Single-side polished finish: The wafer is single-side polished with an etched back side, which may not be suitable for applications requiring double-side polished surfaces or uniform optical reflectivity on both sides.
- Small diameter (2 inch): The 2-inch (50.8 mm) diameter limits compatibility with standard semiconductor fabrication equipment designed for larger wafers, potentially requiring specialized handling or processing adaptations.
