Abstract
A pattern forming apparatus for a base material includes a holding unit and a pattern forming unit. The holding unit is configured to hold a base material on which one of a protrusion shape portion and a recess shape portion is formed. The pattern forming unit is configured to form a pattern on the base material. The pattern is formed on at least one of the protrusion shape portion, the recess shape portion, a periphery of the recess shape portion, a periphery of the protrusion shape portion, a portion along the protrusion shape portion, and a portion along the recess shape portion.
Claims20
A pattern forming apparatus for a base material, comprising:
- a holder to hold the base material on which a protrusion shape portion and a recess shape portion are formed;
- and
- a pattern former to form a pattern on the base material, wherein
- the pattern former applies laser to form the pattern on all of a top portion of the protrusion shape portion, a bottom portion of the recess shape portion, and a side portion of the protrusion shape portion or the recess shape portion,
- the side portion of the protrusion shape portion or the recess shape portion is located between the top portion of the protrusion shape portion and the bottom portion of the recess shape portion,
- the side portion of the protrusion shape portion or the recess shape portion has a surface that is perpendicular to a surface of the top portion of the protrusion shape portion and a surface of the bottom portion of the recess shape portion, and
- the pattern former applies the laser such that a laser focal position is located in a vicinity of the side portion of the protrusion shape portion or the recess shape portion.
A pattern forming method for a base material, comprising:
- preparing the base material on which a protrusion shape portion and a recess shape portion are formed;
- and
- forming a pattern on the base material by:
- applying laser to form the pattern on all of a top portion of the protrusion shape portion, a bottom portion of the recess shape portion, and a side portion of the protrusion shape portion or the recess shape portion,
- the side portion of the protrusion shape portion or the recess shape portion is located between the top portion of the protrusion shape portion and the bottom portion of the recess shape portion,
- the side portion of the protrusion shape portion or the recess shape portion has a surface that is perpendicular to a surface of the top portion of the protrusion shape portion and a surface of the bottom portion of the recess shape portion, and
- applying the laser such that a laser focal position is located in a vicinity of the side portion of the protrusion shape portion or the recess shape portion.
A base material on which a protrusion shape portion and a recess shape portion are formed, the base material comprising:
- a pattern formed on the base material by:
- applying laser to form the pattern on all of a top portion of the protrusion shape portion, a bottom portion of the recess shape portion, and a side portion of the protrusion shape portion or the recess shape portion,
- the side portion of the protrusion shape portion or the recess shape portion is located between the top portion of the protrusion shape portion and the bottom portion of the recess shape portion,
- the side portion of the protrusion shape portion or the recess shape portion has a surface that is perpendicular to a surface of the top portion of the protrusion shape portion and a surface of the bottom portion of the recess shape portion, and
- applying the laser such that a laser focal position is located in a vicinity of the side portion of the protrusion shape portion or the recess shape portion.
