Patent ID: 7608502

Claim:
A method for manufacturing a semiconductor device including a capacitor by depositing a capacitor dielectric film of said capacitor via an atomic layer deposition employing an organic source material containing one or more metallic element(s) selected from the group consisting of Zr, Hf, La and Y as a deposition gas, comprising: obtaining a boundary temperature T (degree C.), at which an increase in a deposition rate for depositing said capacitor dielectric film is detected with increase in a deposition temperature, on the basis of a correlation data of the deposition temperature in the atomic layer deposition employing said deposition gas with a deposition rate for depositing said capacitor dielectric film at the deposition temperature; and depositing said capacitor dielectric film via the atomic layer deposition employing said deposition gas at a temperature within a range of from (T −20) (degree C.) to (T +20) (degree C.), wherein the deposition temperature is 250° C.±40° C.
