    Abstract: The present invention disclose an iris recognition method, which utilizes a matching pursuit algorithm to simplify the extraction and reconstruction of iris features and reduce the memory space required by each iris feature vector without the penalty of recognition accuracy. The iris recognition method of the present invention comprises an iris-localization component and a pattern matching component. The iris-localization component locates the iris region via the color difference between different portions of the eyeball. The primary iris features are extracted from iris information and transformed into a sequence of iris feature vectors by a matching pursuit algorithm. Thus, the iris image can be represented by a sequence of atoms, and each atom contains base, amplitude and location. Then, the comparison between the feature vectors of two irises is performed to determine whether the two irises match.

    Abstract: A method for fabricating the control gate and floating gate of a flash memory cell. An active area is firstly formed on a semiconductor substrate, followed by the formation of a first insulating layer, a first conductive layer and a first masking layer. A first opening is then formed by partially removing the first masking layer, and a floating gate oxide layer is formed by oxidation. The remaining first masking layer is removed, followed by forming a sacrificial layer, which is then partially removed to define a second opening. The remaining sacrificial layer is used as a hard mask to partially remove the first conductive layer and the first insulating layer to form a third opening. A second insulating layer is formed to fill the third opening to form an insulating plug. Part of the first conductive layer and the first insulating layer are removed to form a floating gate, followed by forming a third insulating layer and a second conductive layer. The insulating plug is then used as stop layer to remove part of the second conductive layer and third insulating layer to form a control gate.
