Abstract
An apparatus for manufacturing a silica film is provided. The apparatus includes a conveyor including a mounting unit where a plurality of wafers are loaded. The conveyor is used for moving and transferring the mounting wafers. The apparatus also includes a deposition part for generating flames to deposit silica soot on the plurality of wafers, the deposition part being located above the conveyor, and a calcination part, adjacent to the deposition part, removing water from the silica soot, and a sintering part, adjacent to the calcination part, for deifying the calcined silica soot to form a silica film. The process of manufacturing the silica film can be continuously performed, enhancing productivity.
Claims5
An apparatus for manufacturing a silica film, the apparatus comprising:
- a conveyor including a mounting unit and onto which a plurality of wafers may be loaded, the conveyor moving and thereby moving and transferring the wafers on the conveyor through the apparatus;
- a deposition part located above the conveyor, including at least one torch for sustaining a flame, for depositing silica soot on the wafers located on the conveyor;
- a calcination part, adjacent to the deposition part for heating the silica soot to a calcination temperature to remove water from the silica soot deposited on the wafers;
- and
- a sintering part, adjacent to the calcination part, for heating the silica soot deposited on the wafers to a densification temperature, higher than the calcination temperature, densifying the silica soot to form a silica film on the wafers wherein the wafers are continuously moved from the deposition part, through the calcination part, and to the sintering part by the conveyor.
