What is the typical thickness tolerance and flatness specification for the 2-inch P-type <100> double-side polished silicon wafer?
The wafer has a typical thickness of 400 +/- 25 um with a TTV of less than 5 um, BOW less than 10 um, and WARP less than 10 um. These tight tolerances ensure minimal substrate-induced stress during photolithography and thin-film deposition processes.
Which resistivity ranges are available for this 2-inch P-type silicon wafer, and how do they affect device performance?
Selectable resistivity values include 0.001-0.005 ohm.cm, 1-10 ohm.cm, >10 ohm.cm, >5K ohm.cm, and >10K ohm.cm. Low resistivity (0.001-0.005 ohm.cm) is suitable for power devices requiring low series resistance, while high resistivity (>5K ohm.cm) is preferred for RF or detector applications to minimize substrate losses.
What are the surface roughness specifications for both sides of the double-side polished wafer?
Both the front side and back side have a roughness of Ra less than 0.5 nm. This ultra-smooth finish is critical for epitaxial growth, wafer bonding, or optical applications where surface scattering must be minimized.
This 2-inch P-type <100> double-side polished silicon wafer provides 6N purity and tight geometric tolerances (TTV <5 µm, Ra <0.5 nm) suitable for research-grade thin-film deposition and device prototyping, but requires careful resistivity selection and is limited to P-type doping.
Positive
- High purity 6N monocrystalline silicon: Available in CZ or FZ growth methods, providing low defect density for demanding research applications.
- Tight geometric tolerances: TTV <5 µm, BOW <10 µm, WARP <10 µm, and front-side roughness Ra <0.5 nm ensure consistent wafer-to-wafer performance in lithography and deposition.
Trade-offs
- Limited to P-type doping: Only P-type (boron-doped) wafers are offered, excluding N-type alternatives that may be required for certain device architectures.
- Restricted resistivity selection: Resistivity must be chosen from a discrete set of values (e.g., 0.001-0.005, 1-10, >10, >5K, >10K ohm·cm), limiting continuous tuning for specific electrical properties.
