  • Publication number: 20240242987
    Abstract: Aspects of the disclosure provide a wet etch semiconductor-processing system, which can include a wet processing bath configured to be filled with a processing liquid and configured for one or more semiconductor samples to be placed vertically in parallel therein and immersed in the processing liquid, and a sensor optically coupled to one of the semiconductor samples. The sensor can be configured to form an illumination beam, collect bandgap photoluminescence (PL) light excited by the illumination beam onto a surface of the semiconductor sample at an illuminated spot, and measure spectral intensities of the bandgap PL light in a vicinity of a semiconductor bandgap wavelength of the semiconductor sample. The sensor can be arranged with respect to the wet processing bath such that the sensor directs the illumination beam onto the surface of the semiconductor sample at the illuminated spot and receives the bandgap PL light from the illuminated spot.

  • Patent number: 10529161
    Abstract: An electronic key without a power supply is used for unlocking an electronic door lock of a means of transportation such as an automobile or for unlocking an anti-theft system electronic lock. On the means of transportation, a building, a cabinet or an independent electronic lock, a solar power generation component and a battery that can be replaced externally are installed to supply power to a recognition device such as the electronic key and the electronic lock. An electronic passcode remote control key is firmly fixed on the means of transportation or an outer wall of the building, said key being easily removed and installed by an owner; and may be installed on or around the driver dashboard of the means of transportation, facilitating startup of an engine. A smart mobile phone or the like is used as a key to unlock the door lock of the means of transportation or the building and the anti-theft system lock. This solves the problem that a lock cannot be unlocked when a mobile phone battery is used up.
