Latest Patents

Yi-Cheng Wang holds a patent for a wafer packaging method. This method includes several steps, starting with providing a wafer that has multiple integrated circuit units. The first surface of the wafer, which is opposite to the integrated circuit units, is ground. A release layer is then formed on a second surface of a light transmissive carrier. An ultraviolet temporary bonding layer is created on either the second surface of the light transmissive carrier or the third surface of the wafer. This layer is crucial for adhering the second surface of the light transmissive carrier to the third surface of the wafer. The first surface of the wafer is then adhered to an ultraviolet tape. Finally, the fourth surface of the light transmissive carrier is exposed to ultraviolet light to eliminate the adhesion force of the ultraviolet temporary bonding layer, allowing for the removal of the light transmissive carrier and the release layer.
