Abstract: A semiconductor structure is provided. The semiconductor structure includes a substrate, a diode region, and a dummy stripe. The substrate has a first surface. The diode region is in the substrate. The diode region includes a first implant region of a first conductivity type approximate to the first surface, and a second implant region of a second conductivity type approximate to the first surface and surrounded by the first implant region. The dummy stripe is on the first surface and located between the first implant region and the second implant region. A method for manufacturing a semiconductor structure is also provided.

Abstract: A control method is provided to reduce the spring resonance of a voice coil motor when the coil current of the voice coil motor is changed. Each time a total variation for the coil current to be changed is identified and divided into a plurality of step variations applied one by one with a time step equal to one half of the spring resonant period of the voice coil motor. Due to reduction of the spring resonance, the control method speed up the voice coil motor to a steady state. With this control method, a lens focusing system has a shorter focusing time.
