Latest Patents
One of Joseph Knee's latest patents is the Chemiluminescence Detection Apparatus. This apparatus is designed to detect the presence of a gaseous chemical produced during a chemical-mechanical polishing operation. It includes a catalytic converter, a reaction chamber, and a light sensor. The catalytic converter, heated to about 800°C, converts the chemical to a different product. The reaction chamber produces an excited species while maintaining low pressure to avoid collisional deactivation, allowing for real-time detection of the chemical. The light signal from the excited species is input to the light sensor, providing real-time control of the polishing operation.
Another significant invention is the Probe for Slurry Gas Sampling. This device enables in-situ collection of a gaseous reaction product from a polishing slurry while a workpiece, such as a semiconductor wafer, is being polished. The probe is designed to be in contact with the slurry and features a channel for transmitting the gaseous reaction product to an analyzer. It includes a hydrophobic membrane that allows the gaseous reaction product to pass from the slurry to the channel, along with means for directing a carrier gas through the channel.
