摘要:
An integrated circuit device having a capacitor structure. In one form of the invention, an integrated circuit device includes a capacitor structure formed along a surface of a semiconductor layer. The capacitor structure includes a trench region formed in the semiconductor surface, a layer of dielectric material formed along a wall of the trench region and a first layer of doped polysilicon formed over the layer of dielectric material in the trench region. The capacitor structure further includes a second layer of doped polysilicon formed over the first layer of polysilicon.
