First and second redistribution layer patterns are formed on a semiconductor substrate including a chip region and a scribe lane region to provide a bonding pad portion and an edge pad portion, respectively. A polymer pattern is formed to reveal the bonding pad portion and a portion of the edge pad portion. A dicing line is set on the scribe lane region. A stealth dicing process is performed along the dicing line to separate a semiconductor chip including the bonding pad portion from the semiconductor substrate.

When the pad is squeezed out, it can enter the air cavity, which can prevent the protective layer from being lifted up or cracked, and avoid the pad from overflowing. At the same time, the bonding wire squeezed into the air cavity during bonding process increases the contact area between the pad and the supporting layer, thereby enhancing the stability of the overall structure.
