Abstract
A wafer packaging method includes the following steps. A wafer having a plurality of integrated circuit units is provided. A first surface of the wafer opposite to the integrated circuit units is ground. A release layer is formed on a second surface of a light transmissive carrier. An ultraviolet temporary bonding layer is formed on the second surface of the light transmissive carrier or a third surface of the wafer. The ultraviolet temporary bonding layer is used to adhere the second surface of the light transmissive carrier to the third surface of the wafer. The first surface of the wafer is adhered to an ultraviolet tape. A fourth surface of the light transmissive carrier is exposed to ultraviolet to eliminate adhesion force of the ultraviolet temporary bonding layer. The light transmissive carrier and the release layer are removed.
