The invention discloses a method and an apparatus for prededusting. The method allows a dusty gas to enter into the prededusting apparatus at a tangent from an inlet. Dust in an airflow moves along the inner wall of a cylinder body, slides into a dust collector and is discharged from a dust discharge port because of centrifugal force generated by airflow rotation. A conical reflection screen is arranged in the cylinder body, most of the airflow entering into the cylinder body is reflected upward because of the effect of the reflection screen, and only a small amount of the gas enters into the dust collector with dust particles, so a case that the dust which has been already separated is rewinded up and taken away by a secondary gas can be prevented, thereby the dedusting effect is improved. A certain gap between the reflection screen and the cylinder body is kept, so the dust can enter into the dust collector through the gap; and simultaneously an air-vent is arranged on the top of the reflection screen, so the small amount of the gas entering into the dust collector can enter into the cylinder body through the air-vent. So the apparatus has the characteristics of low equipment cost, stable working condition, and simple and convenient maintenance.

Over a front surface of a silicon semiconductor wafer is deposited a high dielectric constant film with a silicon oxide film, serving as an interface layer, provided between the semiconductor wafer and the high dielectric constant film. After a chamber houses the semiconductor wafer, a chamber's pressure is reduced to be lower than atmospheric pressure. Subsequently, a gaseous mixture of ammonia and nitrogen gas is supplied into the chamber to return the pressure to ordinary pressure, and the front surface is irradiated with a flash light, thereby performing post deposition annealing (PDA) on the high dielectric constant film. Since the pressure is reduced once to be lower than atmospheric pressure and then returned to ordinary pressure, a chamber's oxygen concentration is lowered remarkably during the PDA. This restricts an increase in thickness of the silicon oxide film underlying the high dielectric constant film by oxygen taken in during the PDA.
