Ozonated water mixture supply apparatus and method, and substrate treating facility with the apparatus
First Claim
1. An ozonated water mixture supply apparatus comprising:
- a treating liquid supply line supplying a treating liquid;
an ozonated water supply line supplying an ozonated water; and
a mixing line respectively receiving the treating liquid and the ozonated water from the treating liquid supply line and the ozonated water supply line and mixing the treating liquid and the ozonated water using an in-line mixing method to generate an ozonated water mixture.

Abstract
Provided are an ozonated water mixture supply apparatus and method, and a substrate treating facility that receives an ozonated water mixture from the apparatus to treat a substrate. The ozonated water mixture supply apparatus includes a mixing line and distribution lines. The mixing line respectively receives a treating liquid and an ozonated water from a treating liquid supply line and an ozonated water supply line and mixes the treating liquid and the ozonated water to generate the ozonated water mixture satisfying a previously set concentration. Each of the distribution lines distributes the ozonated water mixture generated from the mixing line into a process unit. The mixing line includes a mixing valve and a static mixer. Therefore, the ozonated water mixture having the previously set concentration is generated and supplied using an in-line mixing method without requiring a mixing vessel such as a mixing tank.
