Abstract: PURPOSE: A method for manufacturing a dual damascene interconnection is provided to prevent contact resistance generated between an interconnection and a via contact from being increased by a defective overlap, by automatically making an interconnection as an upper layer pattern overlap a via contact as a lower layer pattern. CONSTITUTION: The first interlayer dielectric(12), an etch blocking layer(14) and the second interlayer dielectric(16) are sequentially stacked on a semiconductor substrate(10) having a predetermined conductive pattern(11) to form a multilayered insulating layer for defining a dual damascene interconnection region. A predetermined width of the second interlayer dielectric and the etch blocking layer is eliminated to form an opening exposing an upper portion of the first interlayer dielectric. A sidewall spacer is formed by surrounding both sidewalls of the opening with the first interlayer dielectric, the second interlayer dielectric and a material having a large etch selectivity. A bottom portion of the opening is extended downward to expose the conductive pattern while a predetermined width of the second interlayer dielectric on both sides of the sidewall spacer is removed to expose the etch blocking layer. The exposed etch blocking layer and the sidewall spacer are eliminated to form a dual damascene interconnection pattern having a via contact hole(26) and an interconnection region(28). The via contact hole and the interconnection region are filled with a conductive material to complete a dual damascene interconnection.

Abstract: PURPOSE: A method for settling the price of goods using a mobile terminal is provided to conveniently pay the price for goods transactions, without the necessity of using cash. CONSTITUTION: In case that a user purchases goods at a specific store and pays the price for goods, an infrared transmit-receive communication terminal installed in the store transmits the data of the goods price to an infrared transceiver part. The infrared transceiver part converts the data into an infrared signal and transmits the signal to the user's portable phone by wireless(S10). The portable phone, receiving the infrared signal, restores it into the original data. An MSM(Mobile Station Modem) installed in the portable phone outputs a password input request message with the restored goods price on an LCD(S11). If the user inputs the password after judging that the price is reasonable, the MSM transmits approval data, comprised of the password, the MIN(Mobile Identification Number) and the portable phone's ESN(Electronic Serial Number), to an infrared port. The infrared port converts the received approval data into an infrared signal and transmits the converted signal to the infrared transmit-receive communication terminal(S12). At the same time, the MSM makes settlement approval request data, composed of the password, the MIN, the ESN and the price of goods, in the form of a short message in order to request the settlement of the goods price(S20). The MSM transmits the short message to a radio transmitting part so that the message can be transferred to a related goods settlement server through a CDMA base station(S21).
