Abstract

A bowl includes a body portion having a recovery hole to which a recovery line is connected, a guide portion extending upwardly from an upper portion of the body portion and then extending in a lateral direction, and a connection frame installed across the inside of the body portion and the inside of the guide portion.

First claim

What is claimed is:

1 . A bowl comprising:
a body portion having a recovery hole to which a recovery line is connected; a guide portion extending upwardly from an upper portion of the body portion and then extending in a lateral direction; and a connection frame installed across the inside of the body portion and the inside of the guide portion, wherein the connection frame includes a zigzag pattern with a plurality of first portions being vertically disposed and a plurality of second portions being horizontally disposed.

2 . The bowl of claim 1 , wherein
the connection frame includes: the plurality of first portions disposed across the body portion and the guide portion, the plurality of first portions disposed to be spaced apart from each other; and the plurality of second portions connecting the plurality of first portions to each other, and a portion of the plurality of second portions is disposed in the body portion, and a remaining portion of the plurality of second portions is disposed in the guide portion.

3 . The bowl of claim 2 , wherein
a portion of the plurality of second portions connect one ends of the plurality of first portions to each other, and a remaining portion of the plurality of second portions connect the other ends of the plurality of first portions to each other.

4 . The bowl of claim 2 , wherein
a plurality of exhaust holes are formed in the body portion to be spaced apart from each other, and the first portion is disposed between the plurality of exhaust holes.

5 . The bowl of claim 1 , wherein the connection frame has a pipe structure in which a refrigerant flows.

6 . The bowl of claim 5 , wherein the connection frame has one end connected to a refrigerant supply pipe and the other end connected to a refrigerant recovery pipe.

7 . The bowl of claim 1 , wherein the body portion and the guide portion are integrally formed.

8 . The bowl of claim 1 , wherein the guide portion has an extension protruding inwardly to be thicker than the body portion.

9 . The bowl of claim 1 , wherein a ring-shaped reinforcing member is installed on an inner circumferential surface of the guide portion.

10 . A substrate processing apparatus comprising:
a process chamber; a processing container installed within the process chamber, the processing container having a processing space for processing a substrate; a support configured to support the substrate in the processing space; and a nozzle configured to discharge a liquid to the substrate, wherein the processing container includes a plurality of bowls disposed on a circumference of the support, and at least one of the plurality of bowls includes: a body portion having a cylindrical structure, the body portion having a recovery hole to which a recovery line is connected; a guide portion extending upwardly from an upper portion of the body portion and then extending in a lateral direction; and a connection frame installed across the inside of the body portion and the inside of the guide portion, wherein the connection frame includes a zigzag pattern with a plurality of first portions being vertically disposed and a plurality of second portions being horizontally disposed.

11 . The substrate processing apparatus of claim 10 , wherein the connection frame includes:
the plurality of first portions disposed across the body portion and the guide portion, the plurality of first portions disposed to be spaced apart from each other; and the plurality of second portions connecting the plurality of first portions to each other, and a portion of the plurality of second portions is disposed in the body portion, and a remaining portion of the plurality of second portions is disposed in the guide portion.

12 . The substrate processing apparatus of claim 11 , wherein
a portion of the plurality of second portions connect one ends of the plurality of first portions to each other, and a remaining portion of the plurality of second portions connect the other ends of the plurality of first portions to each other.

13 . The substrate processing apparatus of claim 11 , wherein
a plurality of exhaust holes are formed to be spaced apart from each other in the body portion, and the first portion is disposed between the plurality of exhaust holes.

14 . The substrate processing apparatus of claim 10 , wherein the connection frame has a pipe structure in which a refrigerant flows.

15 . The substrate processing apparatus of claim 14 , wherein the connection frame has one end connected to a refrigerant supply pipe and the other end connected to a refrigerant recovery pipe.

16 . The substrate processing apparatus of claim 15 , wherein
the refrigerant supply pipe and the refrigerant recovery pipe are connected to each other by a circulation pump, and a heat exchanger is installed in the refrigerant supply pipe.

17 . The substrate processing apparatus of claim 10 , wherein the body portion and the guide portion are integrally formed.

18 . A method of manufacturing a bowl, the method comprising:
preparing a mold formed such that a first space and a second space, respectively corresponding to a body portion and a guide portion connected to one end of the body portion, are connected to each other; disposing a connection frame across the first space and the second space; and injecting a molten material into the first space and the second space and integrally molding the body portion and the guide portion while fixing the body portion and the guide portion to the connection frame, wherein the connection frame includes a zigzag pattern with a plurality of first portions being vertically disposed and a plurality of second portions being horizontally disposed.

19 . The method of claim 18 , wherein in the disposing, each of the plurality of first portions of the connection frame is disposed across the first space and the second space, and a portion of the plurality of second portions of the connection frame, connecting the plurality of first portions to each other, is disposed in the first space, and a remaining portion of the plurality of second portion is disposed in the second space, and
the first portion and the second portion are disposed to be alternately connected to each other.

20 . The method of claim 18 , wherein in the disposing, a pipe in which a refrigerant is flowable is used as the connection frame.
