Abstract
A crucible assembly for deposition and an inner plate used in the crucible assembly. The crucible assembly includes a main body having an inner space accommodating a deposition material and an opening arranged at an upper portion of the inner space, a cap having an aperture arranged at a top of the main body and combined with the main body and an inner plate arranged between the main body and the cap, the inner plate covering the opening of the main body, the crucible assembly including inner channels arranged to allow vapor of the deposition material from the inner space of the main body to be expelled to an outside of the aperture in the cap via a space arranged between an outer side surface of the inner plate and an inner side surface of the cap.
Claims12
A crucible assembly, comprising:
- a main body having an inner space accommodating a deposition material and an opening arranged at an upper portion of the inner space;
- a cap having an aperture arranged at a top of the main body and combined with the main body;
- and
- an inner plate arranged between the main body and the cap, the inner plate covering the opening of the main body the crucible assembly including inner channels arranged to allow vapor of the deposition material from the inner space of the main body to be expelled to an outside of the aperture in the cap via a space arranged between an outer side surface of the inner plate and an inner side surface of the cap, wherein the inner plate comprises:
- a base member;
- a partition wall arranged at a middle portion of the base member in a thickness direction of the base member, the partition to partition an interior of the base member into first and second floor spaces:
- an inlet allowing the first floor space to be exposed from a bottom side of the base member;
- an outlet allowing the second floor space to be exposed from a top side of the base member;
- a plurality of first channels to allow the first floor space to communicate with an outer side surface of the base member;
- and
- a plurality of second channels to allow the second floor space to communicate with the outer side surface of the base member.
