WaferPro 4″ (100mm) Polished Silicon Wafer


At WaferPro, we specialize in producing high quality polished silicon wafers for semiconductor and electronics applications. Our 100mm polished silicon wafers offer prime quality single crystal monocrystalline material with tightly controlled electrical resistivity and thickness variation specifications. This product consists of 100mm diameter silicon wafers sliced from a single crystal ingot grown using the Czochralski (CZ) method. They have been either single side polished or double side polished to achieve exceptional thickness uniformity, particle performance, surface microroughness, and flatness specifications.

Key Specifications:

Key Features:

  • Premium Quality – All silicon wafers are brand new, virgin silicon wafers – they have never been used or reused
  • Epi-Ready Surface – Our Prime grade silicon wafers have premium epi-ready surfaces
  • Monocrystalline Material – All wafers are made from prime grade monocrystalline silicon material
  • Exceed Industry Standards – Our 100mm silicon wafers exceed SEMI standard specifications and industry standards
  • Versatile Applications – Our 100mm silicon wafers are suitable for a wide range of applications, including semiconductor manufacturing, research and development, and educational purposes
  • Trusted by Industry Leaders – Our 100mm silicon wafers are extensively used by leading semiconductor fabs, R&D centers, universities, and pilot lines around the world
  • Quality Control and Inspection – Every wafer undergoes comprehensive quality inspection and testing
  • Secure Packaging – Wafers are packaged in dedicated ultra-clean PP cassettes and double-bagged in antistatic bags under class 100 cleanroom conditions to protect surface from particulate contamination
  • Competitive Pricing – WaferPro offers competitive pricing with quantity discounts available
  • Certificate of Conformance – A COC is included with each order stating exact specifications of the wafers
