Patent ID: 8628616

Claim:
A vapor-phase process apparatus, comprising: a process chamber in which a reaction gas flows; a plurality of gas introduction portions formed in a wall portion of said process chamber along a direction of flow of said reaction gas; and a flow-guide plate formed to cover said gas introduction portion in said process chamber and guiding a gas supplied from said gas introduction portion into said process chamber such that the gas flows in a direction along the direction of flow of said reaction gas, said flow-guide plate being formed in the wall portion of said process chamber where said gas introduction portions are formed, to extend in a direction of width intersecting the direction of flow of said reaction gas, a plurality of the gas introduction portions are formed in the direction of width, said flow-guide plate covers the plurality of gas introduction portions formed in the direction of width and the flow-guide plate is formed apart from a surface of the wall portion of the process chamber, and a clearance between the flow-guide plate and the surface of the wall portion constitutes a flow path of the gas supplied from the gas introduction portion.
