Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a first movable portion, a second movable portion, a first driving assembly, and a second driving assembly. The first movable portion is movable relative to the fixed portion. The second movable portion is used for holding an optical element having a main axis, and is movable relative to the first movable portion. The first driving assembly is used for driving the first movable portion to move in a first dimension relative to the fixed portion, and the second driving assembly is used for driving the second movable portion to move in a second dimension relative to the fixed portion. The first dimension and the second dimension are different.

Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A method of manufacturing a semiconductor device includes the following steps. A photoresist layer is formed over a material layer on a substrate. The photoresist layer has a composition including a solvent and a first photo-active compound dissolved in the solvent. The first photo-active compound is represented by the following formula (A1) or formula (A2): Zr12O8(OH)14(RCO2)18 ??Formula (A1); or Hf6O4(OH)6(RCO2)10 ??Formula (A2). R in the formula (A1) and R in the formula (A2) each include one of the following formulae (1) to (6): The photoresist layer is patterned. The material layer is etched using the photoresist layer as an etch mask.

Abstract: A twin dimming controller for backlight system is disclosed. In the present invention, the output of pulse width modulation modulator is used as a reference voltage of error-feedback amplifier and frequency compensation loop in backlight controller having pulse dimming control, and meanwhile, the output of pulse width modulation modulator is sent to the output terminal of error-feedback amplifier and frequency compensation loop. Therefore, by utilizing the present invention, the peaked lamp current and the working period of lamp current are adjusted at the same time for adjusting the output power of lamp, and with the same working period of lamp current, the dimming range is broader, and the minimum power consumption of lamp is decreased substantially.
