    • PURPOSE: A method for forming a pad of a semiconductor device is provided to prevent damage or peeling off of interlayer dielectric layers underneath the pad owing to an external wire bonding onto the pad. CONSTITUTION: The method includes forming metal layers(23,25) for interconnection extended under the pad(27). In the method, after an oxide layer(22) is formed on a semiconductor substrate(21), the first metal layer(23) is formed thereon and etched to form the first interconnection layer. Next, the first interlayer dielectric layer(24) is formed thereon and etched to expose a portion of the first metal layer(23). The second metal layer(25) is then formed over a resultant structure and etched to form the second interconnection layer. Next, the second interlayer dielectric layer(26) is formed on the first interlayer dielectric layer(24) and the second metal layer(25), and then etched to expose a portion of the second metal layer(25). Thereafter, a metal layer for the pad(27) is formed over a resultant structure and etched to form the pad(27). Next, a passivation layer(28) is formed thereon and etched to expose the pad(27). The first and second metal layers(23,25) under the pad(27) not only support the pad(27) but also provide electrical connection between the interconnection layers and the pad(27).
    • 目的:提供一种用于形成半导体器件的焊盘的方法,以防止由于焊盘上的外部引线接合而在焊盘下面的层间电介质层的损坏或剥离。 构成:该方法包括形成用于在垫(27)下延伸的互连的金属层(23,25)。 在该方法中,在半导体衬底(21)上形成氧化物层(22)之后,在其上形成第一金属层(23)并形成第一互连层。 接下来,在其上形成第一层间介质层(24)并进行蚀刻以暴露第一金属层(23)的一部分。 然后在所得结构上形成第二金属层(25)并进行蚀刻以形成第二互连层。 接下来,在第一层间电介质层(24)和第二金属层(25)上形成第二层间电介质层(26),然后蚀刻以暴露第二金属层(25)的一部分。 此后,在所得结构上形成用于焊盘(27)的金属层,并蚀刻以形成焊盘(27)。 接下来,在其上形成钝化层(28)并进行蚀刻以露出焊盘(27)。 衬垫(27)下面的第一和第二金属层(23,25)不仅支撑焊盘(27),而且还提供互连层和焊盘(27)之间的电连接。

    • PURPOSE: A dispense device is to suppress generation of foreign matters caused by solidification of an SOG(spin on glass) solution by removing a nozzle head and changing a cleaning manner of a supplying nozzle. CONSTITUTION: A supplying nozzle(51) supplies an SOG solution to a wafer to apply an SOG coating to the wafer. The supplying nozzle is moved to an SOG coating position and a rinse position by a nozzle arm. A receive cap(53) is located below the supplying nozzle to clean the supplying nozzle when it is moved to the rinse position. A cleaning fluid supplying tube(55) located at the receive cap injects a cleaning fluid towards the supplying nozzle to remove the SOG solution smeared at an end of the supplying nozzle when the nozzle is moved to the rinse position. At least two cleaning fluid supplying tubes are formed at a circumference of the receive cap. A drain port(57) is formed at the receive cap to discharge the cleaning fluid being dropped after being injected through the cleaning fluid supplying tube to clean the supplying nozzle. An assistant supplying tube(59) is formed between the cleaning fluid supplying tube and the drain port to flow additional cleaning fluid to the drain port.
    • 目的:分配装置是通过除去喷嘴头和改变供应喷嘴的清洁方式来抑制由SOG(旋转玻璃)溶液固化引起的异物的产生。 构成:供应喷嘴(51)将SOG溶液供应到晶片以将SOG涂层施加到晶片。 供应喷嘴通过喷嘴臂移动到SOG涂覆位置和冲洗位置。 接收帽(53)位于供应喷嘴下方,以便当其被移动到冲洗位置时清洁供应喷嘴。 位于接收帽处的清洗液供给管(55)向喷嘴喷射清洗流体,以在喷嘴移动到冲洗位置时去除涂在喷嘴端部的SOG溶液。 在接收帽的圆周处形成至少两个清洁液供给管。 排出口(57)形成在接收帽处,以便在通过清洁流体供应管被注入以清洁供应喷嘴之后排出被滴落的清洗流体。 辅助供给管(59)形成在清洗流体供给管和排出口之间,以将额外的清洁流体流向排出口。
