Disclosed herein is an image stabilization mechanism for a camera module. The image stabilization mechanism includes a base, a movable stage receiving a lens barrel therein and having a magnet, and a piezoelectric actuator. The piezoelectric actuator is installed to the base, moves the movable stage in an X-axis or Y-axis direction to remove shake of the lens barrel, and maintains contact with the movable stage because of magnetic attractive force between the piezoelectric actuator and the magnet. The image stabilization mechanism reduces the number of components, thus simplifying the structure and minimizing an increase in height.
摘要:
A capacitor is made by forming a buffer oxide layer, an etching stop layer, and a mold insulation layer over a semiconductor substrate having a storage node contact plug. The mold insulation layer and the etching stop layer are etched to form a hole in an upper portion of the storage node contact plug. A tapering layer is deposited over the mold insulation layer including the hole. The tapering layer and the buffer oxide layer are etched back so that the tapering layer is remained only at the upper end portion of the etched hole. A metal storage node layer formed on the etched hole over the remaining tapering layer. The mold insulation layer and the remaining tapering layer are removed to form a cylindrical storage node having a tapered upper end. A dielectric layer and a plate node are formed over the storage node.
