Abstract

An object of the present invention is to provide a treatment liquid for manufacturing a semiconductor, a pattern forming method using the same, and a method of manufacturing an electronic device using the same. The treatment liquid for manufacturing a semiconductor comprising: one kind or two or more kinds of metal atoms selected from Cu, Fe, and Zn, wherein a total content of particulate metal including at least one kind of the metal atoms is 0.01 to 100 mass ppt with respect to a total mass of the treatment liquid for manufacturing a semiconductor.

Claims (20)

1. A treatment liquid for manufacturing a semiconductor comprising:

one kind or two or more kinds of metal atoms selected from Cu, Fe, and Zn,

wherein a total content of particulate metal including at least one kind of the metal atoms is 0.01 to 100 mass ppt with respect to a total mass of the treatment liquid for manufacturing a semiconductor.

2. The treatment liquid for manufacturing a semiconductor according to claim 1 ,

wherein a mass of the particulate metal is measured by a SP-ICP-MS method.

3. The treatment liquid for manufacturing a semiconductor according to claim 1 , which is a developer or a rinsing liquid.

4. The treatment liquid for manufacturing a semiconductor according to claim 1 , comprising:

a quaternary ammonium salt.

5. The treatment liquid for manufacturing a semiconductor according to claim 1 , further comprising:

at least one selected from the group consisting of butyl acetate, N-methyl-2-pyrrolidone, isopropanol, ethanol, and methyl isobutyl carbinol.

6. A pattern forming method comprising:

a step of applying an actinic ray-sensitive or radiation-sensitive resin composition to a substrate to form an actinic ray-sensitive or radiation-sensitive film;

a step of exposing the actinic ray-sensitive or radiation-sensitive film; and

a step of treating the substrate or the actinic ray-sensitive or radiation-sensitive film using the treatment liquid for manufacturing a semiconductor according to claim 1 .

7. The pattern forming method according to claim 6 ,

wherein the pattern forming method comprises at least a step of developing the actinic ray-sensitive or radiation-sensitive film by using the treatment liquid for manufacturing a semiconductor as a developer as the step of treating the substrate or the actinic ray-sensitive or radiation-sensitive film using the treatment liquid for manufacturing a semiconductor.

8. The pattern forming method according to claim 6 ,

wherein the pattern forming method comprises at least a step of cleaning the actinic ray-sensitive or radiation-sensitive film by using the treatment liquid for manufacturing a semiconductor as a rinsing liquid as the step of treating the substrate or the actinic ray-sensitive or radiation-sensitive film using the treatment liquid for manufacturing a semiconductor.

9. A method of manufacturing an electronic device comprising:

the pattern forming method according to claim 6 .
