Latest Patents

One of his latest patents involves methods and apparatus for cleaving a substrate in a semiconductor chamber. In this innovative process, the semiconductor chamber pressure is adjusted to a specific process pressure. A substrate is then heated to a nucleation temperature of ions implanted in the substrate. Following this, the temperature of the substrate is adjusted below the nucleation temperature of the ions, and this temperature is maintained until cleaving of the substrate occurs. Microwaves may be utilized to provide the necessary heating of the substrate during these processes. Additionally, a cleaving sensor can be employed to detect successful cleaving by monitoring pressure changes, acoustic emissions, changes within the substrate, and/or residual gases released by the implanted ions when cleaving takes place.
