Abstract

A device capable of performing surface treatment evenly to an upper portion of a substrate is provided. An upper end of a substrate 54 is sandwiched and held by a clip 52 of a hanger 50. A pipe 56 as a treatment solution releasing section is provided on each side of the substrate 54 that is held by the hanger 50. This pipe 56 is provided with a hole 58 from which the treatment solution is released obliquely upward. The released treatment solution flows down on a surface of the substrate 54, reaches a lower portion thereof, is circulated by a pump 60, and is released from the pipe 56 again.

First claim

What is claimed is:

1. A surface treatment device comprising:
a holding member that holds an upper portion of a treatment target;
a treatment solution releasing section that releases a treatment solution from a pipe onto the holding member and causes the treatment solution to flow down and onto a surface of the treatment target held by the holding member, the treatment solution releasing section being provided in a tank, the treatment solution releasing section releasing the treatment solution, wherein the treatment solution does not fill the tank; and
a transferring mechanism that changes a relative position of the treatment target, which is held by the holding member, to the treatment solution releasing section.

2. The surface treatment device according to claim 1 , wherein:
at least a part of the holding member has such thickness that, when flowing on a surface of the holding member toward the treatment target, the released treatment solution flows perpendicularly with respect to the surface of the treatment target and reaches the treatment target.

3. The surface treatment device according to claim 2 , wherein:
a corner of a lower end of the holding member that holds the treatment target has a curved surface shape in a cross section.

4. The surface treatment device according to claim 2 , wherein:
a lower end of the holding member that holds the treatment target has a semi-circular shape in a cross section.

5. The surface treatment device according to claim 1 , wherein:
a plurality of holding members are provided and are configured such that a plurality of treatment targets are transferred with a specified space being interposed therebetween, and
the plurality of the holding members are configured such that the treatment solution also flows through the space between the treatment targets.

6. The surface treatment device according to claim 5 , wherein:
the plurality of the holding members are configured such that each holding member is also located in an upper portion of the space between the adjacent treatment targets.

7. The surface treatment device according to claim 6 , wherein:
the plurality of the holding members are configured such that an end of the treatment target overlaps a part of the adjacent holding member of the plurality of holding members.

8. The surface treatment device according to claim 5 , wherein:
a guide is provided at an end of each of the plurality of holding members such that the treatment solution flows toward the treatment target held by the adjacent holding member.

9. The surface treatment device according to claim 1 , wherein:
the treatment target is a thin plate, and
the holding member is configured to sandwich the thin plate from both sides, is provided with gripping projections to sandwich the thin plate on inner sides, and is provided with an adhesion prevention projection to avoid adhesion of the thin plate to the holding member.

10. The surface treatment device according to claim 1 , wherein:
the treatment solution releasing section is provided at a plurality of positions in a transferring direction of the treatment target,
at least one of the treatment solution releasing sections releases a plating solution, and at least another one thereof releases a cleaning solution, and
the treatment solution releasing sections are configured that a position where the treatment solution releasing section releasing the plating solution applies the plating solution to the holding member is lower than a position where the treatment solution releasing section releasing the cleaning solution applies the cleaning solution to the holding member.

11. A surface treatment device comprising:
a holding member that holds an upper portion of a treatment target;
a treatment solution releasing section that causes a treatment solution to flow from a pipe onto a surface of the treatment target held by the holding member; and
a transferring mechanism that changes a relative position of the treatment target held by the holding member with respect to the treatment solution releasing section, wherein
a plurality of the holding members are provided and are configured such that the treatment targets are transferred with a specified space being interposed therebetween, and
wherein the treatment solution also flows through the space between the treatment targets and the treatment solution releasing section is provided in a tank, the treatment solution releasing section releasing the treatment solution, wherein the treatment solution does not fill the tank.
