Method for manufacturing stamp and method for manufacturing wire grid polarizer using the stamp

A method for manufacturing at least one wire grid polarizer, the method comprising:

• preparing a mold that includes mold protrusions, wherein the mold protrusions extend parallel to each other in a plan view of the mold and include a first mold protrusion;
• providing first resin on the mold, wherein the first resin partially covers the mold protrusions without completely covering the mold protrusions, and wherein a first side of the first resin is at a first angle with respect to the first mold protrusion in a plan view of a structure that includes the mold and the first resin;
• curing the first resin to form first cured resin;
• forming a first stamp that includes the first cured resin;
• pressing the first stamp on first mask material for forming a first mask;
• etching a first metal film through the first mask to form wires of a first wire grid polarizer;
• providing second resin on the mold, wherein the second resin partially covers the mold protrusions without completely covering the mold protrusions, wherein a first side of the second resin is at a second angle with respect to the first mold protrusion in a plan view of a structure that includes the mold and the second resin, and wherein the second angle is unequal to the first angle;
• curing the second resin to form second cured resin;
• forming a second stamp that includes the second cured resin;
• pressing the second stamp on second mask material for forming a second mask;
• and
• etching a second metal film through the second mask to form wires of a second wire grid polarizer;
• and
• rotating the mold before providing the second resin on the mold.
