Latest Patents

Chunchao Fei holds a patent for a wafer dicing method. This disclosure provides wafer dicing methods and relates to the field of semiconductor technologies. Implementations of the dicing method may include performing laser stealth dicing processing on a wafer from the back surface of the wafer. After performing the laser stealth dicing processing, grinding and thinning processing is conducted on the back surface of the wafer. Following this, a dicing tape is stuck on the back surface of the wafer, and separation processing is performed on the wafer after sticking the dicing tape. In some implementations, stealth dicing is performed before grinding, allowing a laser to be directly imposed on the back surface of a wafer. This approach alleviates a laser attenuation problem and lowers the requirements on light transmittance of a dicing tape.
