Latest Patents

One of his latest patents involves non-volatile semiconductor memory elements and methods of making them. This invention is characterized by a non-volatile metal-insulator-semiconductor that features a unique combination of insulating layers, including a titanium dioxide layer covered by a silicon dioxide layer. In one embodiment, the insulator combination also includes a second layer of silicon dioxide situated between the titanium dioxide and the semiconductor. Additionally, another embodiment incorporates a layer of silicon nitride positioned between the titanium dioxide layer and the semiconductor. The fabrication of these memory elements employs a novel sequence of steps for forming multiple dielectric layers. The titanium dioxide, specifically of the rutile type, is created by evaporating titanium metal onto the silicon dioxide and oxidizing the titanium in an oxygen-rich environment at elevated temperatures. Writing to the memory is achieved by injecting charge into the titanium dioxide layer, which shifts the threshold voltage of the structure. Erasure is performed by forcing the injected charge back into the semiconductor to recombine with majority carriers, with the charge being either electrons or holes depending on the semiconductor type. This innovative memory element boasts lower write/erase voltages, shorter write/erase times, and enhanced memory retentivity.
