Latest Patents

Evans’ latest patents illustrate his inventive prowess. One of his key inventions is the "Ultra thin oxynitride and nitride/oxide stacked gate dielectrics fabricated by high pressure technology." This innovation involves the creation of a dense and stable dielectric layer suitable for use in transistors of ultra-large scale integration (ULSI) circuits. It utilizes a high-pressure process in which a nitride layer is formed on a silicon substrate, followed by a silicon dioxide layer. This configuration minimizes the diffusion of dopant ions from the gate into the silicon dioxide, addressing the challenges posed by the scaling down of semiconductor devices and reducing the thermal budget required in the manufacturing process.

Another notable patent is the "Ink maintenance sensor." This apparatus and method are designed to detect and correct evaporation from recirculated unused ink drops in an inkjet printer. By comparing the specific gravity of recirculating ink with a standard, the device measures the time of fall of heavy floats through both circulated and uncirculated fluid. Significant differences in fall times trigger the replenishment of fluid, ensuring optimal performance of the ink supply system.
