Custom Silicon Wafer Specifications

Custom silicon wafer fabrication and specialty silicon substrates

Researchers often require silicon wafers that fall outside standard semiconductor specifications. Custom wafers can be fabricated with specialized dimensions, thicknesses, crystal orientations, resistivities, thermal oxide layers, nitride coatings, and polished surface finishes.

Available options include:

  • Diameters from less than 1 inch to 300mm (12 inch)
  • Custom thicknesses from ultra-thin to extra-thick
  • P-type and N-type doping
  • Float Zone (FZ) silicon or Czochralski (CZ) silicon
  • Custom notch and flat configurations
  • Prime, test, and mechanical grades
  • Custom resistivity ranges

These custom specifications allow engineers and scientists to optimize substrates for specific device architectures and fabrication processes.

Custom Wafer Orientations

UniversityWafer can supply wafers with standard and specialty crystallographic orientations. While <100> and <111> orientations are common, many research projects require less common orientations, high-index planes, and custom off-cuts.

Available orientations include:

  • <100>
  • <111>
  • <110>
  • <112>
  • <211>
  • <510>
  • Custom off-axis orientations

Custom crystal orientations are frequently used for MEMS fabrication, anisotropic etching, photonics, and advanced semiconductor device development.

Ultra-Thin Silicon Wafers

Thin silicon wafers are commonly used in MEMS, sensors, flexible electronics, microfluidics, advanced packaging, and biomedical devices. These wafers can be manufactured with extremely tight thickness tolerances and low total thickness variation (TTV).

Benefits of thin silicon wafers include:

  • Reduced device weight
  • Improved thermal performance
  • Enhanced flexibility
  • Lower material consumption
  • Compatibility with advanced packaging technologies

Silicon-On-Insulator (SOI) and Epitaxial Wafers
