Description: Tencor Surfscan 7700
(Surfscan 7700)
Tencor Surfscan 7700 Pattern Wafer InpectionSystem
* Substrate sizes: 100mm, 125mm, 150mm & 200mm * Patterned Wafer Inspection System. * Can detect defects as small as 0.15 ¿m, while defects below 0.2 ¿m can be detected on many process levels, including nitride, oxide, polysilicon and TEOS films. * Capable of measuring defects on unpatterned wafers and measuring wafers from 4¿ to 8.¿ * High sensitivity on after-etch and high topography applications. * Circular input polarization enhances sensitivity and defect capture on post-CMP and other post-deposited layers.
