1. An assembly of a liner and a flange, the liner being configured to extend in the interior of a low pressure tube of a vertical furnace, the liner comprising:
- a substantially cylindrical wall delimited by a liner opening at a lower end and a top closure at a higher end and being substantially closed for gases above the liner opening and defining an inner space, the flange being configured to at least partially close an opening of the low pressure tube and comprising;
an inlet opening configured to insert and remove a boat configured to carry substrates in the inner space of the liner; and
a gas inlet to provide a gas to the inner space, wherein the assembly is constructed and arranged with a gas exhaust duct to remove gas from the inner space and a space between the liner and the low pressure tube through a gas exhaust opening in the flange.

Abstract
An assembly of a liner and a flange for a vertical furnace for processing substrates is provided. The liner being configured to extend in the interior of a process tube of the vertical furnace, and the flange is configured to at least partially close a liner opening. The liner comprising a substantially cylindrical wall delimited by the liner opening at a lower end and closed at a higher end and being substantially closed for gases above the liner opening and defining an inner space. The flange comprising:
- an inlet opening configured to insert and remove a boat configured to carry substrates in the inner space of the liner;
- a gas inlet to provide a gas to the inner space. The assembly is constructed and arranged with a gas exhaust opening to remove gas from the inner space and a space between the liner and the low pressure tube.
