Abstract
A method of manufacturing a semiconductor device including a capacitor structure is provided, including the steps of providing an SOI wafer comprising a substrate, a buried oxide (BOX) layer formed over the substrate and a semiconductor layer formed over the BOX layer, removing the semiconductor layer in a first region of the wafer to expose the BOX layer, forming a dielectric layer over the exposed BOX layer in the first region, and forming a conductive layer over the dielectric layer. Moreover, a semiconductor device including a capacitor formed on a wafer is provided, wherein the capacitor comprises a first capacitor electrode comprising a doped semiconductor substrate of the wafer, a capacitor insulator comprising an ultra-thin BOX layer of the wafer and a high-k dielectric layer formed on the ultra-thin BOX layer, and a second capacitor electrode comprising a conductive layer formed over the high-k dielectric layer.
