Title: The Innovative Contributions of Heinz Stuenzi
Introduction
Heinz Stuenzi is a notable inventor based in Hombrechtikon, Switzerland. He has made significant contributions to the field of chemical-mechanical polishing through his innovative patents. With a total of 2 patents, Stuenzi has developed technologies that enhance the efficiency and effectiveness of polishing operations.
Latest Patents
Stuenzi's latest patents include a chemiluminescence detection apparatus and a probe for slurry gas sampling. The chemiluminescence detection apparatus is designed to detect the presence of a gaseous chemical produced during a chemical-mechanical polishing operation. This apparatus features a catalytic converter, a reaction chamber, and a light sensor. The catalytic converter, heated to about 800°C, converts the chemical into a different product. The reaction chamber maintains low pressure to avoid collisional deactivation of excited species, allowing for real-time detection of the chemical. The light signal from the excited species is captured by the light sensor, enabling real-time control of the polishing operation.
The probe for slurry gas sampling is a device that collects gaseous reaction products in situ from a polishing slurry. This probe can be placed in contact with the slurry, featuring 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.
