Abstract

Official abstract text for this publication.

Provided is a substrate holding apparatus capable of appropriately holding a substrate. The substrate holding apparatus is suggested to hold a substrate including a portion to be plated that is exposed to a plating solution and an edge portion that is an area outside the portion to be plated. The substrate holding apparatus comprises a grasp module to come in contact with the edge portion of the substrate and thereby grasp the substrate, a suction module to attract the portion to be plated of the substrate by suction to hold the portion to be plated, and a protrusion provided at a position corresponding to the portion to be plated in the substrate, and protruding toward the substrate to be held by the substrate holding apparatus more than the suction module.

First claim

Opening claim text (preview).

What is claimed is: 1. A substrate holding apparatus to hold a substrate including a portion to be plated that is exposed to a plating solution and an edge portion that is an area outside the portion to be plated, the substrate holding apparatus comprising: a gripper configured to come in contact with the edge portion of the substrate and thereby grasp the substrate: a suction mechanism configured to attract the portion to be plated of the substrate by suction to hold the portion to be plated; and a protrusion provided at a position corresponding to the portion to be plated of the substrate, and protruding toward the substrate held by the substrate holding apparatus more than the suction mechanism protrudes toward the substrate. 2. The substrate holding apparatus according to claim 1 , wherein the protrusion is disposed to come in contact with a scribe line of the substrate. 3. The substrate holding apparatus according to claim 1 , wherein a tip of the protrusion has a curved surface. 4. The substrate holding apparatus according to claim 1 , wherein the protrusion is made of an antistatic material. 5. The substrate holding apparatus according to claim 1 , wherein the protrusion is provided at a position closer to a suction position by the suction mechanism than to a grasp position by the gripper. 6. The substrate holding apparatus according to claim 1 , wherein the protrusion is fixed to a base body of the substrate holding apparatus. 7. The substrate holding apparatus according to claim 1 , wherein the suction mechanism is a vacuum chuck or Bernoulli chuck. 8. A substrate holding apparatus to hold a substrate, comprising: a gripper configured to come in contact with an edge portion of the substrate and thereby grasp the substrate; a suction mechanism configured to attract a first plate surface of the substrate by suction to hold the first plate surface; and a protrusion provided at a position corresponding to a central side in the first plate surface away from a suction position by the suction mechanism, and protruding toward the substrate held by the substrate holding apparatus more than the suction mechanism protrudes toward the substrate.
