Latest Patents
One of his latest inventions is the Aluminum Deposition Shield. This innovative shield substantially improves the transfer of radiated heat from within a vacuum chamber, outperforming traditional stainless steel shields. The aluminum deposition shield remains cooler during wafer processing, which assists in cooling the chamber components effectively.
Another significant invention by Ashok K Das is the Non-intrusive, On-the-fly (OTF) Temperature Measurement and Monitoring System. This apparatus provides a method for measuring the temperature of a moving radiant object. A probe, such as a pyrometer, is strategically placed in an opening of a vacuum chamber adjacent to a radiation transparent window. The probe defines an optical path that intercepts the radiant object entering or exiting the processing chamber. As the radiant object moves through the optical path, it emits electromagnetic waves. These waves are collected by the probe and transmitted to a signal processing unit, where they are detected and converted into a temperature reading. The accumulated data can be used to generate a cooling curve that represents the thermal effects experienced by the radiant object.
