For planar RF structures made on oxidized High Resistivity (HR) Si substrates, it is fundamental to keep the resistivity near the SiO/sub 2 //HR Si interface as high as possible. This paper presents a quantitative analysis of the influence of interface states at the SiO /sub 2//Si contact on the substrate resistivity. The starting materials for this study are raw HR substrates before or after SOI bonding process. These HR Si wafers were fabricated with either a Low (LIO) or a High Interstitial Oxygen (HIO) concentration.
