摘要:
A system of supplying processing fluid to a substrate processing apparatus having walls, the inner surfaces of which define a processing chamber in which a substrate supporting susceptor is located. The system consists of a number of fluid storages, each which stores a separate processing fluid, at least two fluid conduits along which processing fluid flows from the fluid storages to the processing apparatus and a fluid inlet which connects the fluid conduits to the processing chamber. The inlet has a separate fluid passage, corresponding to each of the fluid conduits, formed along it. Each fluid passage opens at or near an inner surface of a wall to together define a fluid mixing zone, so that fluid moving along one fluid passage is prevented from mixing with fluid moving along any other passage until reaching the mixing zone.

The present disclosure is directed to an apparatus for depositing a layer of a material on a wafer. The apparatus includes a deposition chamber having an upper dome, a lower dome and a side wall between the upper and lower domes. A susceptor plate is in and extends across the deposition chamber to divide the deposition chamber into an upper portion above the susceptor plate and a lower portion below the susceptor plate. An exhaust passage formed through the side wall and is coupled to an upper passage which extends to the upper portion of the deposition chamber and is coupled to a lower passage which extends to the lower portion of the deposition chamber.

A susceptor plate is in and extends across the deposition chamber to divide the deposition chamber into an upper portion above the susceptor plate and a lower portion below the susceptor plate. A gas inlet manifold is in the side wall. The manifold has three inlet ports. One of the ports is connected by passages which open into the lower portion of the deposition chamber. The other two ports are connected by passages which open into the upper portion of the deposition chamber. A gas supply system is connected to the inlet ports so as to provide the same gases into the lower portion of the deposition chamber as well as into the upper portion of the deposition chamber. This allows the back surface of the susceptor plate to be coated with a layer of the same material as to be coated on the wafer prior to coating the layer on the wafer.

摘要:
An apparatus and a concomitant method for controlling coolant (air) flow proximate a reaction chamber within a workpiece processing system such that the temperature of a wall of the reaction chamber is maintained at a predefined target temperature. The target temperature is typically a temperature that optimizes a process concurrently being accomplished within the chamber, e.g., utilizing one temperature during deposition processes and a different temperature during cleaning processes. The apparatus contains a temperature measuring device to measure the temperature of the chamber wall. The measured temperature is compared to the predefined target temperature. A closed loop system controls the air flow proximate the chamber walls such that the measured temperature becomes substantially equal to the target temperature. Air flow control is provided by an air flow control device located within an inlet conduit that supplies air to a shroud for channeling the air past the reaction chamber. The shroud forms a portion of a housing which supports and encloses the reaction chamber.

An apparatus for depositing a material on a wafer includes a susceptor plate mounted in a deposition chamber. The chamber has a gas inlet and a gas exhaust. Means are provided for heating the susceptor plate. The susceptor plate has a plurality of support posts projecting from its top surface. The support posts are arranged to support a wafer thereon with the back surface of the wafer being spaced from the surface of the susceptor plate. The support posts are of a length so that the wafer is spaced from the susceptor plate a distance sufficient to allow deposition gas to flow and/or diffuse between the wafer and the susceptor plate, but still allow heat transfer from the susceptor plate to the wafer mainly by conduction. The susceptor plate is also provided with means, such as retaining pins or a recess, to prevent lateral movement of a wafer seated on the support posts.
