Abstract
A method for forming a mark includes ejecting a droplet of a liquid from a nozzle onto an ejection target position on a surface of an object along an ejecting direction; radiating a laser beam from a radiation port onto the ejection target position along a radiating direction; and pivoting the nozzle and the radiation port together about the ejection target position as a pivot center, thereby changing the angle between a normal line of the surface of the object and the ejecting direction and the angle between the normal line and the radiating direction while maintaining the angle between the ejecting direction and the radiating direction.
Claims2
A method for forming a mark comprising:
- ejecting a droplet of a liquid from a nozzle onto an ejection target position on a surface of an object along an ejecting direction;
- radiating a laser beam from a radiation port onto the ejection target position along a radiating direction;
- and
- pivoting the nozzle and the radiation port together about the ejection target position as a pivot center, thereby changing the angle between a normal line of the surface of the object and the ejecting direction and the angle between the normal line and the radiating direction while maintaining the angle between the ejecting direction and the radiating direction.
