Patent ID: 6951787

Claim:
A method of fabricating a capacitor dielectric material in a capacitor, comprising the steps of: forming the capacitor dielectric material to contain hydrogen and adjusting a composition of the capacitor dielectric material by controlling a stoichiometry of the capacitor dielectric material in order to adjust an amount of the hydrogen contained in the capacitor dielectric material and to obtain predetermined electrical or functional characteristics of the capacitor, by forming the capacitor dielectric material from substances including silicon, nitrogen and hydrogen, forming the capacitor dielectric material to include hydrogen bonds therein by depositing the substances by using plasma enhanced chemical vapor deposition, breaking a predetermined number of the hydrogen bonds to the capacitor dielectric material by ionic bombardment to allow the hydrogen from the broken bonds to escape from the capacitor dielectric material, controlling the power of the plasma enhanced chemical vapor deposition to establish the extent of the ion bombardment, and controlling the amount of the hydrogen remaining in the formed capacitor dielectric material by controlling the power of the plasma enhanced chemical vapor deposition.
