Key Features of the 8-Inch P/N Type Silicon Wafer
P/N Type Doping Options
P-Type Wafers: Doped with boron (B) for positive charge carriers (holes), ideal for power devices and analog circuits.
N-Type Wafers: Doped with phosphorus (P) or arsenic (As) for electron-based conductivity, preferred for high-speed digital ICs and solar cells.
1~100Ω Resistivity Range
Tailored resistivity ensures compatibility with diverse applications, from low-power sensors to high-current power devices.
Dust-Free Surface
Manufactured in cleanroom environments to minimize particulate contamination, critical for high-yield lithography and thin-film deposition.
Single-Sided Polishing
One side is mirror-polished for photolithography and device fabrication, while the unpolished side provides mechanical stability during handling.
Advantages of Single-Sided Polished & Dust-Free Design
Enhanced Process Control: The polished side ensures uniformity in photoresist coating and etching.
Reduced Defects: Dust-free surfaces minimize particle-induced failures during fabrication.
Cost Efficiency: Single-sided polishing lowers production costs while maintaining performance.
Versatility: Compatible with CVD, PVD, and epitaxial growth processes.
