  • Patent number: 7623959
    Abstract: The present invention relates to a method and system for providing voice-based supplementary information service using road map data. The voice-based supplementary information service system includes a content registration server for receiving content for the voice-based supplementary information service, and converting the content into supplementary information data having voice data format. At least one GPS satellite detects a location of the mobile communication terminal and transmits GPS radio waves, including the location information. A mobile communication terminal receives the location information and requests the road guidance service and the supplementary information service. A relay server relays requests for the road guidance service and the supplementary information service. A road search server generates road map data and transmits the road map data to the relay server. A user management server determines whether the request for the supplementary information service exists in the road map data.

  • Patent number: 7329365
    Abstract: An etchant for removing an indium oxide layer includes sulfuric acid as a main oxidizer, an auxiliary oxidizer such as H3PO4, HNO3, CH3COOH, HClO4, H2O2, and a Compound A that is obtained by mixing potassium peroxymonosulfate (2KHSO5), potassium bisulfate (KHSO4), and potassium sulfate (K2SO4) together in the ratio of 5:3:2, an etching inhibitor comprising an ammonium-based material, and water. The etchant may remove desired portions of the indium oxide layer without damage to a photoresist pattern or layers underlying the indium oxide layer.

  • Patent number: 5953617
    Abstract: A method for manufacturing an optoelectronic integrated circuit including a photo diode for transforming light into electric signals, an HBT for amplifying said electric signals from said photo diode, a capacitor, and a resistor is disclosed. An HBT including an emitter, a base, and a collector on a predetermined location of a semiconductor substrate, and a photo diode including an N type metal, non doped layer, and a P type metal are formed. A lower electrode of a capacitor is formed on the semiconductor substrate located in a place separated by a predetermined space from said photo diode. A SiN film is deposited over the surface of the resulting structure of the semiconductor substrate. The above described SiN film is patterned to exist only on the surfaces of the HBT, photo diode, lower electrode, and semiconductor substrate separated from the lower electrode by a predetermined space. Furthermore, a resistor is formed on the SiN film existing on a predetermined surface of the semiconductor substrate.
