Abstract:
1. A capacitor comprising: a silicon substrate; a first silicon dioxide layer over the silicon substrate; a silicon nitride fin projecting vertically from and in contact with the first silicon dioxide layer, the silicon nitride fin including a first side wall and a second sidewall; a first silicon film in physical contact with the first sidewall of the silicon nitride fin; a second silicon film in physical contact with the second sidewall of the silicon nitride fin, the second silicon film spaced apart from and not in contact with the first silicon film; and a dielectric layer over the silicon nitride fin, the dielectric layer directly in contact with the silicon nitride fin and the silicon film; a second silicon dioxide layer between the dielectric layer and the silicon nitride fin; a first metal via in electrical contact with the first silicon film; and a second metal via in electrical contact with the second silicon film.
