Latest Patents
Sandroff's latest patents include innovative techniques that enhance the performance of semiconductor devices. One of his patents, titled "Temperature measurement in a processing chamber using in-situ monitoring," describes a method that utilizes a simple optical monitoring technique to measure temperature within a processing chamber. This technique involves optically exciting a III-V direct-bandgap semiconductor to emit photoluminescence (PL). The spectral resolution of the emitted PL provides a direct measure of the bandgap of the semiconductor, allowing for the derivation of the temperature from the bandgap measurement.
Another significant patent is "Semiconductor laser passivation and overstressing." This method aims to improve the reliability of InGaAsP lasers by subjecting them to sulfide passivation, which passivates defects on their facets. The lasers are then tested for internal defects, ensuring that only those with increased reliability to electrostatic discharge (ESD) remain in use. This process greatly enhances the ESD failure level for facet defects, thereby improving the overall reliability of the lasers.
