Abstract

Official abstract text for this publication.

A substrate holding mechanism includes a substrate holding claw for holding the substrate. The substrate holding claw includes a slant face for sliding the substrate thereon. Height of the slant face is increased from the inside of a space for holding the substrate toward the outside of the space. A crossing angle formed by a direction in which a machining mark is formed on the slant face and a direction in which the substrate is slid is not less than 0 degree and not more than 45 degrees at least in a partial region of the slant face.

First claim

Opening claim text (preview).

What is claimed is: 1. A substrate holding mechanism comprising: a substrate holding claw for holding the substrate, wherein the substrate holding claw includes a slant face for sliding the substrate thereon, height of the slant face being increased from the inside of a space for holding the substrate toward the outside of the space, wherein a machining mark including at least one of a linear mark and substantially parallel marks is formed on the slant face, and wherein a crossing angle of a direction in which the at least one of the linear mark and the substantially parallel marks is formed and a direction in which the substrate is slid is not less than 0 degree and not more than 45 degrees at least in a partial region of the slant face. 2. The substrate holding mechanism according to claim 1 , wherein the crossing angle is not more than 30 degrees. 3. The substrate holding mechanism according to claim 1 , wherein the crossing angle is 0 degree. 4. The substrate holding mechanism according to claim 1 , wherein the at least one of the linear mark and the substantially parallel marks is formed substantially in parallel to a direction in which the slant face is slanted. 5. A substrate turnover device comprising: a substrate holding mechanism including a substrate holding claw for holding the substrate, wherein the substrate holding claw includes a slant face for sliding the substrate thereon, height of the slant face being increased from the inside of a space for holding the substrate toward the outside of the space, wherein a machining mark including at least one of a linear mark and substantially parallel marks is formed on the slant face, and wherein a crossing angle of a direction in which the at least one of the linear mark and the substantially parallel marks is formed and a direction in which the substrate is slid is not less than 0 degree and not more than 45 degrees at least in a partial region of the slant face. 6. A substrate transporting device comprising: a substrate holding mechanism including a substrate holding claw for holding the substrate, wherein the substrate holding claw includes a slant face for sliding the substrate thereon, height of the slant face being increased from the inside of a space for holding the substrate toward the outside of the space, wherein a machining mark including at least one of a linear mark and substantially parallel marks is formed on the slant face, and wherein a crossing angle of a direction in which the at least one of the linear mark and the substantially parallel marks is formed and a direction in which the substrate is slid is not less than 0 degree and not more than 45 degrees at least in a partial region of the slant face. 7. A semiconductor manufacturing apparatus comprising: a substrate holding mechanism including a substrate holding claw for holding the substrate, wherein the substrate holding claw includes a slant face for sliding the substrate thereon, height of the slant face being increased from the inside of a space for holding the substrate toward the outside of the space, wherein a machining mark including at least one of a linear mark and substantially parallel marks is formed on the slant face, and wherein a crossing angle of a direction in which the at least one of the linear mark and the substantially parallel marks is formed and a direction in which the substrate is slid is not less than 0 degree and not more than 45 degrees at least in a partial region of the slant face. 8. A substrate holding mechanism comprising: a substrate holding claw for holding the substrate, wherein the substrate holding claw includes a slant face for sliding the substrate thereon, height of the slant face being increased from the inside of a space for holding the substrate toward the outside of the space, wherein a machining mark including at least one of a linear mark and substantially parallel marks is formed on the slant face, and wherein a crossing angle of a direction in which the at least one of the linear mark and the substantially parallel marks is formed and a direction in which the substrate is slid is not less than 0 degree and not more than 45 degrees at least in a partial region of the slant face, and wherein the at least one of the linear mark and the substantially parallel marks is formed substantially in parallel to a direction in which the slant face is slanted.
