Abstract

The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a chamber providing a treating space; and a fluid supply unit supplying a treating fluid to the chamber, and wherein the fluid supply unit includes: a supply tank storing the treating fluid; a supply line connecting the supply tank and the chamber; and a plurality of valves installed at the supply line, and wherein any one valve among the plurality of valves is provided as a safety valve, and wherein the safety valve is opened after confirming that the chamber has been switched to a closed state when supplying the treating fluid from a tank to the chamber.

First claim

1 . A substrate treating apparatus comprising:
a chamber providing a treating space; and a fluid supply unit supplying a treating fluid to the chamber, and wherein the fluid supply unit comprises: a supply tank storing the treating fluid; a supply line connecting the supply tank and the chamber; and a plurality of valves installed at the supply line, and wherein any one valve among the plurality of valves is provided as a safety valve, and wherein the safety valve is opened after confirming that the chamber has been switched to a closed state when supplying the treating fluid from a tank to the chamber.

2 . The substrate treating apparatus of claim 1 , wherein the safety valve is provided closest to the supply tank among the plurality of valves.

3 . The substrate treating apparatus of claim 1 , wherein the safety valve and a remaining valve except for the safety valve among the plurality of valves are controlled by different control modules.

4 . The substrate treating apparatus of claim 3 , wherein the safety valve is controlled by a first control module, and the remaining valve is controlled by a second control module, and
wherein the first control module comprises: a first controller controlling an open/close of the safety valve; and a safety controller controlling an operation of the first controller, and wherein the safety controller controls a power supplied to the first controller to control the first controller.

5 . The substrate treating apparatus of claim 4 , wherein the first control module further comprises a relay operated by receiving a power supply signal of the safety controller and transmitting a power supplied by the safety controller to the first controller.

6 . The substrate treating apparatus of claim 4 , wherein the fluid supply unit further comprises an integrated controller controlling the plurality of valves, and
wherein the first controller receives an open signal of the integrated controller and an open signal of the safety controller to control the safety valve to open the safety valve.

7 . The substrate treating apparatus of claim 1 , wherein the safety valve includes a solenoid valve.

8 . The substrate treating apparatus of claim 1 , wherein the safety valve includes a normal close valve (N/C valve)

9 . The substrate treating apparatus of claim 1 , wherein the supply tank is a high pressure tank, and the chamber is a high pressure chamber.

10 . A substrate treating apparatus comprising:
a chamber providing a treating space; a fluid supply unit supplying a treating fluid to the chamber, and wherein the fluid supply unit comprises: a supply tank storing the treating fluid; a supply line connecting the supply tank and the chamber; and a plurality of valves installed at the supply line; and a control module controlling the plurality of valves, and wherein a safety valve provided closest to a tank among the plurality of valves is controlled by another valve and another control module.

11 . The substrate treating apparatus of claim 10 , wherein the safety valve is controlled to supply the treating fluid after confirming that the chamber has been switched to a closed state when supplying the treating fluid from the tank to the chamber.

12 . The substrate treating apparatus of claim 10 , wherein the safety valve is controlled by a first control module,
a remaining valve except for the safety valve among the plurality of valves is controlled by a second control module, and wherein the first control module comprises: a first controller controlling an open/close of the safety valve; a safety controller controlling an operation of the first controller; and a relay operated by receiving a signal of the safety controller and transmitting a power supplied by the safety controller to the first controller, and wherein the safety controller controls a power supplied to the first controller to control the first controller.

13 . The substrate treating apparatus of claim 10 , wherein the safety valve is a normal close valve (N/C valve).
