  • Patent number: 10658239
    Abstract: 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 a back surface of the wafer; performing grinding and thinning processing on the back surface of the wafer after performing the laser stealth dicing processing; sticking a dicing tape on the back surface of the wafer after performing the grinding and thinning processing; and performing separation processing on the wafer after sticking the dicing tape. In some implementations, stealth dicing (SD) is performed before grinding, so that a laser is directly imposed on a back surface of a wafer, thereby alleviating a laser attenuation problem and lowering requirements on light transmittance of a dicing tape.

  • Patent number: 8815615
    Abstract: A method of forming interconnects in integrated circuits includes providing a semiconductor substrate and forming a copper interconnect structure that is formed overlying a barrier layer within a thickness of an interlayer dielectric layer. The copper interconnect structure has a first stress characteristic. The method further loads the semiconductor substrate including the copper interconnect structure into a deposition chamber that contains an inert environment. The semiconductor substrate including the copper interconnect structure is annealed in the inert environment for a period of time to cause the copper interconnect structure to have a second stress characteristic. The semiconductor substrate is maintained in the deposition chamber while an etch stop layer is deposited thereon. The method further deposits an intermetal dielectric layer overlying the etch stop layer, wherein the annealing reduces copper hillock defects resulting from at least the first stress characteristic.
