A pixel cell includes a substrate, an epitaxial layer, and a photo converting device in the epitaxial layer. The epitaxial layer has a doping concentration profile of embossing shape, and includes a plurality of layers that are stacked on the substrate. The photo converting device does not include a neutral region that has a constant potential in the vertical direction. Therefore, the image sensor including the pixel cell has high quantization efficiency, and a crosstalk between photo-converting devices is decreased.

The present invention provides a horizontal linear vibrator which can reduce the thickness but increase the strength of vibrations while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit, a cylindrical coil and springs. The bracket is coupled to the casing to form an internal space. The vibration unit includes a weight, a pair of yokes and magnets. The weight has an opening therein. The yokes are disposed on the inner surfaces of the weight. The magnets are provided in the yokes such that different poles of the magnets face each other. The cylindrical coil is perpendicularly mounted to the bracket and disposed in space between the pair of yoke. The springs are coupled to both ends of the casing or the bracket. The springs elastically support the vibration unit to allow the vibration unit to vibrate in the horizontal direction.

Disclosed herein are an apparatus and a method for driving an e-paper panel. The e-paper panel driving apparatus includes a DC/DC converter that converts and outputs DC voltage to be input into a preset voltage and supplies the output voltage as a driving voltage of an e-paper panel; a sensing module that senses load conditions of the e-paper panel; and a control module that varies the driving frequency of the DC/DC converter according to the load conditions of the e-paper panel sensed by the sensing module. According to the present invention, the driving clock of the DC/DC converter that supplies the driving voltage to the e-paper panel is varied in consideration of the load conditions of the e-paper panel, thereby making it possible to prevent an image quality of the e-paper panel from being degraded due to unstable power supply, while simultaneously minimizing unnecessary power consumption of the e-paper panel driving apparatus.

Backside illumination CMOS image sensors having convex light-receiving faces and methods of manufacturing the same. A backside illumination CMOS image sensor includes a metal layer, an insulating layer and a photodiode. The insulating layer is on the metal layer. The photodiode is on the insulating layer, and a top face of the photodiode, which receives light, is curved. A method of manufacturing a backside illumination CMOS image sensor including a photodiode having a convex surface includes forming an island smaller than the photodiode on a portion of a light-receiving face of the photodiode, and annealing the island to form the photodiode having the convex light-receiving face.
