    摘要: A method for making a device including a capacitive structure is disclosed. One embodiment provides a carrier layer having a surface. A first dielectric layer is formed on the surface. A silicon layer including silicon grains is formed on the first dielectric layer using a deposition process. A second dielectric layer is formed on the second silicon layer. A layer of an electrically conductive material is formed on the dielectric layer. A temperature process for heating at least the first dielectric layer is performed. The temperature and duration of the temperature process is selected such that the first dielectric layer is modified so that the silicon layer is electrically connected to the carrier layer.
