Abstract: The present invention relates to a system and method for three-dimensional advertising. The system and method of the present invention store advertisement data capable of being rendered as a three-dimensional object, the real position of which is designated. When a mobile communication terminal including a GPS receiver measures its own position, and transmits the position information of the mobile communication terminal to an advertisement server, an advertisement server transmits advertisement data set around the position information of the mobile communication terminal to the mobile communication terminal. The mobile communication terminal renders the advertisement data into a three-dimensional object, and displays the rendered advertisement data by overlapping same with a real image, which is displayed through a camera built in the mobile communication terminal.

Abstract: A lead frame for manufacturing semiconductor device packages has inner leads, tie bars and a die pad that are formed with irregular dimples on their respective upper and lower surfaces. This improves the bonding strength between the lead frame and the molding compound as well as between the die pad and a semiconductor device. The dimples are formed during the manufacture of the lead frame which allows the lead frame to be economically and easily manufactured.
