Abstract
An alignment mark, a semiconductor device, and fabrication methods of the alignment mark and the semiconductor device are provided. The method includes providing a first base substrate, and forming a plurality of alignment marks on the first base substrate. The method also includes dicing the first base substrate to form a plurality of alignment dies. Each alignment die includes a diced first base substrate and at least one alignment mark diced from the plurality of alignment marks on the diced first base substrate. In addition, the method includes providing a second base substrate for aligning, and forming a bonding film on the second base substrate. Further, the method includes attaching an alignment die of the plurality of alignment dies to the bonding film on an alignment region of the second base substrate using a die attach process.
