摘要: Methods and apparatus for cleaving a substrate in a semiconductor chamber. The semiconductor chamber pressure is adjusted to a process pressure, a substrate is then heated to a nucleation temperature of ions implanted in the substrate, the temperature of the substrate is then adjusted below the nucleation temperature of the ions, and the temperature is maintained until cleaving of the substrate occurs. Microwaves may be used to provide heating of the substrate for the processes. A cleaving sensor may be used for detection of successful cleaving by detecting pressure changes, acoustic emissions, changes within the substrate, and/or residual gases given off by the implanted ions when the cleaving occurs.

摘要: A method for dicing a die from a substrate for bonding that leverages laser and multiple etch processes. The method may include performing a laser cutting process to form a cut that removes a first portion of a dicing street in the substrate, performing a first plasma etch process to increase the laser kerf width to a first plasma etch width that is less than a dicing street width and to remove any non-silicon material from a bottom of the cut, and performing a second plasma etch process to increase the first plasma etch width to the dicing street width and to remove any remaining portion of the dicing street to completely separate the die from the substrate.
