Title: The Innovations of Stephane Chamaly
Introduction
Stephane Chamaly is a notable inventor based in Singapore, recognized for his contributions to the field of surface acoustic wave (SAW) technology. With a total of two patents to his name, Chamaly has made significant advancements that enhance the efficiency and cost-effectiveness of SAW devices.
Latest Patents
Chamaly's latest patents include a surface acoustic wave filter on a lithium niobate substrate. This innovative filter utilizes a θ-rotated Y-cut X-propagation lithium niobate substrate, with a cut angle ranging from 20° to 40°. An interdigital transducer is employed to excite a surface acoustic wave formed on the substrate. His second patent addresses the production of lithium niobate SAW wafers containing tantalum (Ta) impurities. The low Ta impurity content in pyrochlore ore allows for the production of niobium pentoxide powders at a lower cost, eliminating the need for a solvent extraction process. This method enables the growth of SAW wafers from melts produced by reacting niobium pentoxide powders containing Ta impurities, achieving good yields and reproducible properties.
