Product Description
Custom Piezoelectric Wafers for POI & MEMS Applications
Piezoelectric wafers convert mechanical pressure into electrical polarization, creating peripheral electric fields through charge displacement. Our specialized manufacturing focuses on high-performance materials including lead zirconate titanate and lithium niobate composites.
Manufacturing Capabilities
BonTek specializes in crystal growth and wafer fabrication with over 30 years of expertise. We process various materials including Quartz Crystal, Lithium Niobate, Lithium Tantalate, Fluoride, and Glass substrates.
Advanced Fabrication Features
- Large diameter wafer production: 3", 4", 6", 8", 12" sizes available
- Ultra-thin processing: 0.1mm thickness for 4" quartz wafers; 0.35mm for 12" wafers
- Corning Flatmaster 200 Profiler for precise TTV, BOW, and WARP measurements
- Laser marking equipment for wafer identification
- SEMI-standard compliance for all wafer specifications
