Photoelastic Imaging of Process Induced Defects in 300mm-Silicon Wafers
Published online by Cambridge University Press: 10 February 2011
Abstract
Process induced crystal defects in silicon wafers can be detected by their stress fields. The nondestructive photoelasticity based on laser polarimetry is applied to visualize the stress fields of temperture gradient induced lattice defects like sliplines or extended defect areas around boat marks. The quantitative evaluation of the defects allows their characterization by a specific danger potential for further evolution causing upstream problems in IC manufacturing.
