In this paper, we have characterized the RF performance of high-k Al2O3 and AlTiOx capacitors and compared with SiO2. We have found that significant k reduction occurs in high-k dielectric and SiO2 at high frequencies and is strong material dependent. This may be a limitation of high-k dielectric. The relatively large shot noise in gate dielectric is strongly dependent on material and sensitive to defect generation after stress.
