Claim:
1. A semiconductor structure, comprising: a substrate; and a plurality of convex structures formed on a surface of the substrate and arranged in a longitudinal direction of the substrate, each convex structure having a top surface, a bottom surface located on the surface of the substrate, a first end surface and a second end surface parallel to each other, and a front side surface and a rear side surface parallel to each other; wherein each of the first end surface and the rear side surface of each convex structure has a shape of a triangle, each of the second end surface and the front side surface of each convex structure has a shape of a trapezium, each of the top surface and the bottom surface of each convex structure has a shape of a quadrangle, each of an intersection line between the second end surface and the rear side surface of each convex structure and an intersection line between the first end surface and the front side surface of the each convex structure is shorter than an intersection line between the second end surface and the front side surface of the each convex structure, top surfaces of the plurality of convex structures are parallel to each other, front side surfaces of the plurality of convex structures are parallel to each other, and the rear side surface of one of two adjacent convex structures and the front side surface of the other are located on a same plane to allow the plurality of convex structures to form a zigzag structure on the surface of the substrate.
