Abstract: A substrate structure and a cutting method thereof are provided. The cutting method includes the following steps. A first substrate structure is provided, wherein the first substrate structure includes a glass substrate and a redistribution layer disposed on the glass substrate. A laser process is performed on the glass substrate to form a modified region on the glass substrate. A wet etching process is performed on the modified region of the glass substrate to remove the modified region and form a plurality of second substrate structures.
