摘要
We propose to use the front and the back gates of a fully depleted SOI transistor to extract the thickness of both the silicon film and the buried oxide, by plotting the variation of the threshold voltage of the transistor driven by one gate versus the bias on the other gate and vice versa. This allows to derive independently both the silicon film and the buried-oxide thicknesses.
