Abstract: Example embodiments are directed to a maskless exposure device and an alignment method. The alignment method performs an overlay of each layer of a plurality of layers on a substrate using a virtual mask in a maskless exposure technique. The maskless exposure device and the alignment method use a virtual mask instead of a physical mask used in a conventional mask exposure, a virtual target mark instead of an alignment mark used in the conventional mask exposure, and perform an overlay per layer, such that the deposition exposure can be achieved in the maskless exposure.

Abstract: Example embodiments are directed to a maskless exposure apparatus using off-axis alignment to form a virtual mask pattern on a substrate. The maskless exposure apparatus includes a movement unit on which the substrate is placed, a light source unit configured to output light, a projection unit configured to divide the light output from the light source unit into a plurality of spot beams to form the pattern and configured to project the spot beams to the movement unit, an alignment unit configured to output alignment light to align the substrate and a virtual mask, a beam imaging unit configured to capture the spot beams and the alignment light, and a controller configured to measure distances between the captured alignment light and at least two of the captured spot beams and configured to determine alignment between the virtual mask and the substrate based on the measured distances to control movement of the movement unit.

Abstract: The present invention relates to a method and system of synchronizing data between a contents providing system and a portable device via network. More particularly, the present invention relates to a method and system of transmitting predetermined data of contents, which requires digital rights protection, to a portable device, wherein a contents providing system and a synchronization information system are connected with a synchronization client installed in a computer to which the portable device is connected.

Abstract: Disclosed are a method for providing a license corresponding to encrypted contents to a client apparatus, which provides a license in response to a request of the license corresponding to contents super-distributed to a third person in a DRM conversion system, and a DRM conversion system using the same. First digital rights contents type first contents and a first license corresponding to the first contents are digital rights management converted to generate second digital rights contents type second contents and a second license corresponding to the second contents. A license request corresponding to the second contents super-distributed to a third person is received. A second license corresponding to the second contents super-distributed is requested from a server corresponding to the second digital right management. The second license corresponding to the second contents super-distributed is received and transmitted to the third person.

Abstract: A pixel of an image sensor includes a first insulating structure, a photoelectric charge-trap structure, a second insulating structure, and a gate electrode. The first insulating structure is formed on a substrate, and the photoelectric charge-trap structure is formed on the first insulating structure. The second insulating structure is formed on the photoelectric charge-trap structure. The gate electrode is formed on the second insulating structure. The photoelectric charge-trap structure converts a significant amount of light reaching the pixel into charge carriers.
