    • Disclosed is a method for forming contacts of a semiconductor device. In accordance with the invention, an oxidized silicon-rich nitride film is used as an etch barrier film for a self-aligned contact (SAC) process. Accordingly, the oxidized silicon-rich nitride film exhibits less stress, as compared to an LPCVD nitride film, thereby being capable of avoiding a degradation in the characteristics of the devices finally produced or distortion of the wafer used. There is no formation of cracks occurring in the nitride film during a subsequent thermal process. It is also unnecessary to conduct an additional reflection preventing process. Accordingly, the entire process is simplified. It is also possible to improve a decrease in the operating speed of the devices due to a parasitic capacitance existing among conductive lines because the oxidized silicon-rich nitride film has a low dielectric constant, as compared to nitride films. No damage occurs in the oxidized silicon-rich nitride film, so that it is possible to prevent the substrate from being damaged.
    • 公开了一种形成半导体器件的接触的方法。 根据本发明,氧化富硅氮化物膜用作自对准接触(SAC)工艺的蚀刻阻挡膜。 因此,与LPCVD氮化物膜相比,氧化富硅氮化物膜的应力显示较小,从而能够避免最终产生的器件的特性劣化或所使用的晶片的变形。 在随后的热处理中,在氮化物膜中不会形成裂缝。 也不需要进行附加的防反射处理。 因此,整个过程被简化。 与氮化膜相比,由于氧化富硅的氮化物膜具有低的介电常数,所以可以改善由于导电线中存在的寄生电容而引起的器件的工作速度的降低。 在氧化富硅的氮化物膜中不会发生损伤,从而可以防止衬底损坏。

    • A method for manufacturing a semiconductor device that can prevent the loss of an isolation structure and that can also stably form epi-silicon layers is described. The method for manufacturing a semiconductor device includes defining trenches in a semiconductor substrate having active regions and isolation regions. The trenches are partially filled with a first insulation layer. An etch protection layer is formed on the surfaces of the trenches that are filled with the first insulation layer. A second insulation layer is filled in the trenches formed with the etch protection layer to form an isolation structure in the isolation regions of the semiconductor substrate. Finally, portions of the active regions of the semiconductor substrate are recessed such that the isolation structure has a height higher than the active regions of the semiconductor substrate.
    • 描述了可以防止隔离结构的损失并且还可以稳定地形成外延硅层的半导体器件的制造方法。 半导体器件的制造方法包括在具有有源区和隔离区的半导体衬底中限定沟槽。 沟槽部分地填充有第一绝缘层。 在填充有第一绝缘层的沟槽的表面上形成蚀刻保护层。 在由蚀刻保护层形成的沟槽中填充第二绝缘层,以在半导体衬底的隔离区域中形成隔离结构。 最后,半导体衬底的有源区的部分被凹入,使得隔离结构的高度高于半导体衬底的有源区。
