Abstract

Patterned oxides buried in bonded silicon-on-insulator (SOI) wafers before thinning have been characterized by near-IR scattering topography and a microscopy combination system. Micron-scaled pinholes in patterned oxides buried in bonded SOI wafers have been observed by the scattering topography. Edges of the patterned oxides have also been observed by both scattering topography and transmission microscopy. With the combination of scattering topography and transmission and reflection microscopy, this system is effective to evaluate the visibility of patterned oxides buried in bonded SOI wafers.
