  • Patent number: 7994050
    Abstract: A method for forming a dual damascene pattern includes preparing a multi-functional hard mask composition including a silicon resin as a base resin, wherein the silicon resin comprises about 20 to 45% silicon molecules by weight, based on a total weight of the resin; forming a deposition structure by sequentially forming a self-arrangement contact (SAC) insulating film, a first dielectric film, an etching barrier film, and a second dielectric film over a hardwiring layer; etching the deposition structure to expose the hardwiring layer, thereby forming a via hole; coating the multi-functional hard mask composition over the second dielectric film and in the via hole to form a multi-functional hard mask film; and etching the resulting structure to expose a part of the first dielectric film using a photoresist pattern as an etching mask, thereby forming a trench having a width greater than that of the via hole.

  • Publication number: 20100177134
    Abstract: An inkjet image forming apparatus and a method of printing an image using the same includes determining the positions and number of defective nozzles incapable of properly spraying ink. It is determined whether the array head is in a printable state or a restoration procedure to restore the defective nozzles to a normal state is required, based on the determined positions and number of the defective nozzles. When the array head is in the printable state, a printing operation may be performed. When the restoration procedure to restore the defective nozzles to a normal state is required, the restoration procedure is performed, the positions and number of the defective nozzles are predetermined, and it is predetermined whether the array head is in the printable state.
