With a noteworthy portfolio of two patents, Roy has made significant strides in technological advancements that enhance the efficacy and reliability of these devices.
Latest Patents
Among his latest inventions is the innovative patent for a magnetoresistive device and barrier formation process. This patent pertains to the formation of a barrier layer composed of an aluminum-titanium oxidic compound, which is approximately 35 angstroms thick. This barrier layer is strategically placed between a first alumina film and an overlying material, such as nickel-iron. The aluminum-titanium oxidic compound layer acts as an etchant barrier during the etching process, effectively minimizing or eliminating the problematic 'rosette' formation caused by trapped etchant within porous substrates like ferrite or ceramic. Furthermore, the barrier layer serves a dual purpose by functioning as a passivation layer, protecting the alumina film from ultrasonic energy transfer during wire bonding processes, thus preventing potential delamination at the nickel-iron/alumina layer interface.
