Apparatus for manufacturing cover window, method for manufacturing cover window, and electronic device including cover window

Abstract

Provided are apparatuses for manufacturing cover window, methods for manufacturing cover window, and electronic devices including cover window. An apparatus for manufacturing a cover window includes a light source outputting a raw laser beam, a beam splitter splitting the raw laser beam into a main beam and at least one sub-beam, a first phase mask diffracting the main beam to convert the main beam into a straight-line beam, a second phase mask diffracting the sub-beam to convert the sub-beam into a dotted-line beam including a plurality of spot beams, a beam combiner combining the main beam and the sub-beam to form a single combined beam, and an objective lens focusing the combined beam onto a focal plane, wherein the beam splitter sets extension directions of a polarization axis of the main beam and a polarization axis of the sub-beam to be different from each other.

Dependencies are inferred from the claim text.
