Stainless steel member and its manufacturing method |
| abstract |
In a stainless steel member having a passivation layer formed on the surface of a base material made of stainless steel, the passivation layer has a thickness of 2 to 20 nm, and the atomic concentration of chromium atoms at the outermost surface of the passivation layer is 0.1 to 2.3 atomic%. And a manufacturing method thereof. In addition, a device or container in which a part in contact with a semiconductor treatment liquid is formed by the stainless steel member, a method for producing a semiconductor treatment liquid for producing a semiconductor treatment liquid using the device, and a semiconductor treatment for storing the semiconductor treatment liquid in the container Provides a method of storing liquid. |
