Abstract: PURPOSE: A method of discounting products in electronic commerce is provided, so that a lottery purchaser can immediately know a prize lot by executing an instant lottery drawing function while performing electronic commerce as well as purchasing a product with a fixed discount rate when the purchaser wins a prize in an instant lottery. CONSTITUTION: A purchaser connects to a shopping mall server to obtain a data link(S10). If the purchaser requests product lists(S12), a server engine transmits the product lists to a terminal of the purchaser. The purchaser selects a demanded product(S14). If an order is received from the purchaser terminal, a prize winning confirm module calculates a purchasing turn of the selected product to confirm whether the purchaser wins a prize in a lottery(S16). If so, the server engine outputs a Web page including a fixed discount rate and a discounted cost to the purchaser terminal(S18). The Web page checks whether a changed discount rate is applied(S20). If so, the changed discount rate is calculated(S22). The server engine transmits a Web page including the changed discount rate and a discounted cost to the purchaser terminal(S24). If the order is successful, a payment processing module performs a payment procedure according to payment information of the order(S28,S26,S30). If the purchaser wants to additionally purchase other product, the server engine retransmits the product lists(S32). If the purchaser does not want an additional purchasing, the purchaser terminal cancels the data link with the shopping mall to complete the procedures(S34).

Abstract: PURPOSE: A method for fabricating a metal interconnection of a semiconductor device is provided to prevent a bridge from being generated between adjacent metal interconnections and reduce fabricating cost while simplifying a fabricating process by using a dual damascene process. CONSTITUTION: An interlayer dielectric(22) and a photoresist layer are sequentially formed on a semiconductor substrate(21). An exposure process is performed on the photoresist layer by using a reticle including a transmission region corresponding to a contact hole formation area and a half transmission region corresponding to a metal interconnection formation area including the transmission region. The exposed photoresist layer is developed to form a photoresist layer pattern having a T-typed pattern that simultaneously defines the contact hole formation area and the metal interconnection formation area. The photoresist layer pattern hard-baked. A predetermined depth of an exposed interlayer dielectric is firstly dry-etched by using the hard-baked photoresist layer pattern. The remaining T-typed pattern of the photoresist layer pattern is eliminated by using oxygen plasma. The interlayer dielectric is secondly etched by using the photoresist layer pattern to form a trench that includes a contact hole exposing the substrate and defines the metal interconnection formation area. The remaining photoresist layer pattern is removed. A metal layer is deposited on the interlayer dielectric to fill the contact hole and the trench. The metal layer is polished until the interlayer dielectric is exposed.
