  • Patent number: 12354931
    Abstract: The present disclosure is directed to semiconductor dies and methods that provide a glass substrate, a pulsed laser tool to produce a line-shaped modification to the glass substrate for forming a plurality of structures in the glass substrate. The pulse laser tool may be provided with a predetermined pattern for its movement. The predetermined pattern moves the pulsed laser tool in a series of single steps in a first axial direction and in a series of plural lateral steps in a second axial direction that is perpendicular to the first axial direction, in particular, the single step is followed by the plural lateral steps in a repeating sequence. The series of plural lateral steps form an assembly of line-shaped modifications in parallel rows on the glass substrate, and thereafter the plurality of structures may be formed from the parallel rows of line-shaped modifications in the glass substrate.
