    摘要: The invention relates to a method for adjusting a micro-bar of an electron microscope to increase the accuracy of the micro-bar. The method entails first forming a photo-resist layer on a semiconductor wafer, and exposing a predetermined region of the photo-resist layer to a light of a specific wavelength. Then, a resist stripping process is performed to remove the photo-resist layer in the predetermined region. The periphery of the predetermined region of the photo-resist layer will form a vertical side wall with a periodic wave shape similar to a sine wave, and the wavelength of the periodic wave shape is determined by the wavelength of the light and the refraction rate of the photo-resist layer. Finally, the micro-bar of the electron microscope is adjusted using the wavelength of the periodic wave shape on the vertical side wall.

    摘要: A dual damascene process involves forming a first passivation layer, a first dielectric layer and a second passivation layer on a substrate of a semiconductor wafer. A first lithography and etching process is performed to form at least one via hole in the second passivation layer and the first dielectric layer. Thereafter, a second dielectric layer and a third passivation layer are formed on the surface of the semiconductor wafer followed by performing a second lithography and etching process to form at least one trench in the third passivation layer and the second dielectric layer. The trench and the via hole together construct a dual damascene structure. Finally, a barrier layer and a metal layer are formed on the surface of the semiconductor wafer, and a chemical-mechanical-polishing (CMP) process is performed to complete the dual damascene process.

    摘要: The present invention fabricates a dual damascene structure. A passivation layer, a first dielectric layer, a second passivation layer, a second dielectric layer, a third passivation layer and a third dielectric layer are formed on the surface of the semiconductor wafer followed by etching the third dielectric layer to form a pattern of an upper trench of the dual damascene structure. Then the third passivation layer and the second dielectric layer are etched down to the surface of the second passivation layer so as to form a pattern of a via hole of the dual damascene structure. Thereafter, the third passivation layer and the second passivation layer not covered by the third dielectric layer and the second dielectric layer are removed. The third dielectric layer and the second passivation layer are used as hard masks to remove the second dielectric layer and the first dielectric layer until the surface of the first passivation layer. Finally, the second passivation layer and the first passivation layer not covered by the second dielectric layer and the first dielectric layer are removed to the surface of the conductive layer so completing the process of fabricating the dual damascene structure.
