• Compact Footprint with effective, high-quality vibration and acoustic isolation
• Multipurpose: Suitable for multilayer structures, no thickness limitations
• High resolution: Nanometer scale depth resolution, high spatial accuracy
• In-situ Bevel Angle Measurement (BAM): Standard feature for precise junction depth analysis
• Stand-Alone Bevel sample polishing unit
• Options:
  
  • PCIV option for wide bandgap and SOI application, which combines variable measurement bias and current-voltage curve analysis to measure spreading resistance profile on novel semiconductor materials
  • Iterative PCIV software option (iPCIV): designed to measure highly variable samples with very high resistance value (ideal below 1E-11 A current range),
  • Shallow Layer Measurement (SLM): extending the SRP technique to determine thin layer structure,
  • Variable Probe Spacing (VPS): motorized probe spacing movement allows the measurement of sheet resistance of thin isolated layers
  • Temperature-controlled measurement chamber (TCM),
