Wafer Technology

Geometric features and the surface have a high importance for the Wafer-Quality. Special Parameters are used for the description of the surface, like GBIR, SFQR, Flatness, Roughness or Nanotopology. Global Geometry is described through Bow, WARP, Thickness, Thickness fluctuations (TTV).

Geometry / Surface

  • Thickness:  100um up to 10mm
  • Diameter: 2″ up to  300mm
  • Bow < 20um
  • Warp < 20 um
  • TTV (GBIR) < 2 um 
  • LTV < 0,4 um (5x5mm2)
  • SFQRmax (26x8mm, 90% PSA) < 0,5um
  • Edge: C-Shape, Beveled, As Cut
  • Semi Standard M001-1105 E
  • Lasermarking  (T7/OCR) SEMI M1
