Her work focuses on developing innovative solutions that enhance the performance and reliability of electronic components.
Latest Patents
One of her latest patents is for a thin film resistor designed for optoelectronic integrated circuits. This invention features a stable low resistance, thin film resistor comprising a bilayer of platinum on titanium. The resistive layer is protected by a dielectric layer, such as silicon dioxide or silicon nitride, which reduces degradation from humidity and high-temperature operations exceeding 300°C. This resistor can be formed on various substrates, including silicon dioxide, silicon nitride, and semiconductor materials. Its applications include integrated resistive heaters for wavelength fine-tuning of semiconductor laser arrays.
Another notable patent involves a method of etching patterns in III-V material with accurate depth control. This method allows for precise control over the depth of etched gratings in uniform or layered quaternary III-V materials. By selectively growing a native oxide on the area to be patterned and subsequently removing it, Margittai can engrave the surface effectively. The periodic repetition of the oxide growth and removal steps results in gratings of the desired depths.
