Abstract
A method of dividing a substrate includes preparing a substrate including a crystalline semiconductor layer having a scribe lane region and device regions, a dielectric layer on the crystalline semiconductor layer, and a partition structure in physical contact with the dielectric layer and provided on the scribe lane region of the crystalline semiconductor layer, forming an amorphous region in the crystalline semiconductor layer, and performing a grinding process on the crystalline semiconductor layer after the forming of the amorphous region. The amorphous region is formed in the scribe lane region of the crystalline semiconductor layer.
