摘要
It is shown that n-well concentration in thin silicon on insulator (SOI) structure decreases drastically due to the pileup of n-type dopant at the surface-SiO2/Si interface. A demonstrative process shows the n-well concentration decreases to 30% in a 0.1 mu m SOI, while that in a 1 mu m SOI decreases to 80%.
