Choosing Silicon Wafers for Polymerization Research

A Ph.D. researcher requested assistance selecting silicon wafers for polymerization studies.

Research Question:
I would like to order silicon wafers for polymerization on the wafer surface. Which wafer specifications do you recommend?

UniversityWafer Recommendation:

For polymerization, surface chemistry experiments, and thin-film deposition, we typically recommend single-side polished (SSP) silicon wafers. Since only the polished surface is exposed to the coating, polishing the backside provides little benefit while increasing cost.

For most laboratory applications we recommend:

  • Orientation: <100>
  • Dopant: Boron (P-type) or Phosphorus (N-type)
  • Resistivity: Greater than 1 Ω-cm
  • Surface: SEMI Prime, SSP
  • Thickness: Standard wafer thickness unless film stress requires additional rigidity

Common wafer diameters include 50.8 mm, 76.2 mm, 100 mm, 125 mm, and 150 mm. Larger diameters are available for production-scale research.
