  • System and method for efficiently performing an inverse telecine procedure
    Patent number: 7136414
    Abstract: A system and method for efficiently performing an inverse telecine procedure includes an inverse telecine module that converts input frames of video information into corresponding output frames by applying an inverse telecine policy to the input frames. A motion statistics generator then calculates motion statistics results corresponding to the output frames. A synchronizer module then compares the motion statistics results to entries in a synchronization table for determining whether the inverse telecine procedure is correctly synchronized. The synchronizer module may then reposition a current start boundary of the inverse telecine procedure whenever the inverse telecine procedure is not correctly synchronized.

  • Method of manufacturing flash memory device
    Patent number: 7132328
    Abstract: The present invention relates to a method of manufacturing a semiconductor device. According to the present invention, an ONO1 HTO film and an ONO2 nitride film are sequentially formed on a polysilicon layer for floating gate and an oxide film for ONO3 is formed as a SiON film by oxidizing the surface of the ONO2 nitride film. Thus, the oxide film for ONO3 having a better film quality and a high dielectric constant compared to an existing HTO oxide film is formed. Accordingly, capacitance and a breakdown voltage are increased and charge leakage and retention properties are thus improved. Furthermore, it is possible to reduce the cost through reduction in process by replacing an ONO3 annealing process and a subsequent high temperature steam annealing process with a single process.
