Deposition rate measuring apparatus
First Claim
1. A deposition rate measuring apparatus, comprising:
- a crystal sensor facing a specific deposition source among a plurality of deposition sources in a deposition apparatus;
a deposition-preventing bracket in a front portion of the crystal sensor, the deposition-preventing bracket having an opening that assists inflow of a specific deposition material, the deposition-preventing bracket extending from the opening, and the deposition-preventing bracket surrounding the crystal sensor to prevent interference due to at least one deposition material from at least one adjacent deposition source adjacent to the specific deposition source; and
one or more cover portions spaced apart from the opening inward of the deposition-preventing bracket by a predetermined length.
