  • Publication number: 20250081572
    Abstract: A semiconductor device structure and methods of forming the same are described. The structure includes a first semiconductor material disposed over a substrate and a dielectric layer disposed on the first semiconductor material. The dielectric layer includes a dopant. The structure further includes a second semiconductor material disposed on the dielectric layer, a first semiconductor layer in contact with the second semiconductor material, and a first dielectric spacer in contact with the first semiconductor layer, wherein the first dielectric spacer includes the dopant.

  • Publication number: 20240345465
    Abstract: The disclosure provides a laser lighting system. The laser lighting system includes a microcontroller, a motor, a fluorescent color wheel and a detection circuit. The motor drives the fluorescent color wheel to rotate. The detection circuit is configured to detect a detected signal from the fluorescent color wheel. When a synchronous signal changes, the microcontroller compares the detected signal to the synchronous signal, in order to control the output current signal for driving the motor, and to decrease the phase variation between the detected signal and the synchronous signal until the phase difference between the detected signal and the synchronous signal maintain at a constant value.
