Abstract
A camera may use one or more actuators to implement various functions. An actuator of a camera may include one or more coil structures. The coil structure may include at least one layer of coil at a first side of a dielectric layer, and at least another one layer of coil at a second side of the dielectric layer opposite the first side. The coils at the two sides of the dielectric layers may have different numbers of turns. In particular, a section of the coil at the second side of the dielectric layer may be left out to cause the different numbers of turns between the coils at the two sides. The coil structure may also include one or more connection pads at the second side of the dielectric layer.
