LASER CRYSTALLIZATION APPARATUS AND LASER CRYSTALLIZATION METHOD USING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18135559 titled 'LASER CRYSTALLIZATION APPARATUS AND LASER CRYSTALLIZATION METHOD USING THE SAME

Simplified Explanation

The laser crystallization apparatus described in the patent application includes a beam generator, a beam converter, and a beam concentrator to improve the crystallization process of silicon films.

  • The beam converter divides the input laser beam into multiple sub beams at a predetermined rotation angle, increasing the stiffness area and decreasing the high-intensity area of the beam profile.
  • The beam concentrator condenses the sub beams into an output laser beam with a predetermined beam width, allowing for a gradual dehydrogenation effect on an amorphous silicon film and minimizing defects in the resulting polycrystalline silicon film.

Original Abstract Submitted

Provided is a laser crystallization apparatus including a beam generator generating an input laser beam, a beam converter dividing an input laser beam incident from a beam generator into a plurality of sub laser beams and disposed to have a predetermined rotation angle with respect to an optical axis parallel to a traveling direction of an input laser beam, and a beam concentrator condensing a plurality of sub laser beams and outputting an output laser beam having a beam profile having a predetermined beam width. Accordingly, a width of a stiffness area of a beam profile of an input laser beam may increase and a width of a high intensity area may decrease. Accordingly, the number of shots for the stiffness area at specific point of an amorphous silicon film may increase. Accordingly, a gradual dehydrogenation effect on an amorphous silicon film may be implemented. Accordingly, occurrence of defects in a polycrystalline silicon film formed by laser crystallization may be minimized or prevented.
