  • Patent number: 11746411
    Abstract: The present invention relates to a method for forming a thin film, and more particularly, to a method for forming a thin film comprising steps of: i) adsorbing a growth inhibitor for forming a thin film on a surface of a substrate, the growth inhibitor for forming a thin film being represented by Chemical Formula 1 below; and ii) adsorbing a Ti-based thin film precursor on a surface of a substrate on which the growth inhibitor is adsorbed. AnBmXo??[Chemical Formula 1] wherein A is carbon or silicon, B is hydrogen or a C1-C3 alkyl, X is a halogen, n is an integer of 1 to 15, o is an integer of 1 or more, and m is 0 to 2n+1. According to the present invention, it is possible to suppress side reactions to appropriately lower a thin film growth rate and remove process byproducts in the thin film, thereby preventing corrosion or deterioration and greatly improving step coverage and thickness uniformity of a thin film, even when the thin film is formed on a substrate having a complex structure.

  • Patent number: 7092555
    Abstract: A system for performing face registration and authentication using face information, and a method thereof. A set of readily distinguishable features for each user is selected at a registration step and only the set of features selected at the registration step is used at a face authentication step, whereby memory use according to unnecessary information and amount of data calculation for face authentication can be reduced. Thus, the present system has an advantage in that identity authentication through face authentication can be performed even under restricted environments of a USB token or smart card with limited resources. The present system further has advantages in that authentication performance is improved, as readily distinguishable feature information is used, and the time for face authentication is reduced, as face authentication is performed using the SVM built by using the optimal set of readily distinguishable features at a training step.
