Apparatus for monitoring process chamber
First Claim
Patent Images
1. An apparatus for monitoring an interior of a process chamber, the apparatus comprising:
- a process chamber including a chamber body and a view port defined in the chamber body;
a cover section including a pinhole in one end, the cover section disposed to correspond to one end portion of the view port, the one end portion of the view port being adjacent to an inner wall of the chamber body, the cover section having a first length in a direction toward a center of the process chamber; and
a sensor inserted into the view port to monitor the interior of the process chamber through the pinhole, a region in the process chamber to be sensed by the sensor determined based on the first length.

13. An apparatus for monitoring an interior of a process chamber, the apparatus comprising:
-
a process chamber including a chamber body, the chamber body including a first view port and a second view port defined therein; a first cover section including a first pinhole, the first cover section disposed to correspond to an one end portion of the first view port, the one end portion of the first view port being adjacent to an inner wall of the chamber body; a first sensor inserted into the first view port to monitor a first sensing region in the interior of the process chamber through the first pinhole; a second cover section including a second pinhole, the second cover section disposed to correspond to an one end portion of the second view port, the one end portion of the second view port being adjacent to the inner wall of the chamber body; and a second sensor inserted into the second view port to monitor a second sensing region in the interior of the process chamber through the second pinhole, the second sensing region being different from the first sensing region. - View Dependent Claims (14, 15, 16)

17. An apparatus for monitoring an interior of a process chamber, the apparatus comprising:
-
a process chamber including a chamber body and at least one view port defined in the chamber body; at least one cover structure coupled into the view port, the cover structure including a pinhole at one end thereof, the cover structure configured to correspond to an one end portion of the view port, the one end portion of the view port being adjacent to an inner wall of the chamber body, the cover structure configured to move forward or backward with respect to the inner wall of the chamber body, the cover structure having a length in a direction toward a center of the process chamber; and at least one sensor accommodated in the cover structure to monitor the interior of the process chamber through the pinhole, a region in the process chamber to be sensed by the sensor determined according to a focal distance of the sensor, the focal distance of the sensor determined based on a distance between the pinhole and the sensor. - View Dependent Claims (18, 19, 20)
