An image sensor capable of boosting a voltage of a floating diffusion node is provided. The image sensor includes a floating diffusion node and a storage element which are in a semiconductor substrate. The image sensor includes a first light-shielding material formed over the floating diffusion node, and a second light-shielding material formed over the storage diode. The second light-shielding material is separated from the first light-shielding material. The image sensor also includes a first voltage supply line configured to apply a first voltage to the first light-shielding material and a second voltage supply line configured to apply a second voltage lower than the first voltage to the second light-shielding material.

A 3D image sensor includes a depth pixel that includes; a photo detector generating photo-charge, first and second floating diffusion regions, a first transfer transistor transferring photo-charge to the first floating diffusion region during a first transfer period in response to a first transfer gate signal, a second transfer transistor transferring photo-charge to the second floating diffusion region during a second transfer period in response to a second transfer gate signal, and an overflow transistor that discharges surplus photo-charge in response to a drive gate signal. Control logic unit controlling operation of the depth pixel includes a first logic element providing the first transfer gate signal, a second logic element providing the second transfer gate signal, and another logic element providing the drive gate signal to the overflow transistor when the first transfer period overlaps, at least in part, the second transfer period.

A method of forming a metal line is provided. A first metal layer and a second metal layer protecting the first metal layer are formed on a base substrate. The first metal layer includes aluminum or aluminum alloy. A photoresist pattern having a linear shape is formed on the second metal layer. The first and second metal layers are dry-etched using etching gas and the photoresist pattern as an etching mask. An etching material is removed from the base substrate, to prevent corrosion of the dry-etched first metal layer. Therefore, the source metal pattern without corrosion may be formed through a dry-etching process so that a manufacturing cost is decreased.

A remote education method and apparatus via an internet which has been widely used as an information network is provided. The remote education method and apparatus via the internet has an open structure which is not influenced by particular hardware or software, such as an operating system or a web browser. A remote education provider can construct a remote education server with a low cost in a minimum amount of time. Also users can easily connect to the remote education server via the internet to receive a remote education service. The remote education server provides an educational program including individual learning progress based on a learning evaluation and a performance management function and performs a discriminative education based on the ability of each individual.
