    • A method for fabricating a semiconductor device includes the steps of: providing a semiconductor device formed with a plurality of transistors; forming a first stress layer with a plurality of layers on the semiconductor device; forming a second stress layer with a plurality of layers on another surface of the semiconductor device; covering photo resist on a region of the first stress layer to cover at least one of the transistors; and performing ion implantation on the part of the semiconductor device that is not covered by the photo resist. In another embodiment, the second stress layers can be formed after the ion implantation. The method can simultaneously enhance the device performance of the PMOS and NMOS on the same wafer. It also solves the problem of procedure integration caused by the produced compressive stress and tensile stress.
    • 一种制造半导体器件的方法包括以下步骤:提供形成有多个晶体管的半导体器件; 在所述半导体器件上形成具有多个层的第一应力层; 在所述半导体器件的另一表面上形成具有多个层的第二应力层; 覆盖所述第一应力层的区域上的光致抗蚀剂以覆盖所述晶体管中的至少一个; 并且对半导体器件的未被光致抗蚀剂覆盖的部分进行离子注入。 在另一个实施例中,可以在离子注入之后形成第二应力层。 该方法可以同时提高同一晶片上的PMOS和NMOS的器件性能。 它也解决了由产生的压缩应力和拉伸应力引起的程序整合问题。

    • A method for fabricating a semiconductor device is provided. The method mainly involves steps of forming at least one first patterned high stress layer below a silicon substrate, then forming a semiconductor device onto the substrate, and forming at least one second patterned high stress layer on the semiconductor device. According to the method, the characteristics of the PMOS and the NMOS transistors formed on the same wafer may be improved simultaneously, by utilizing the stress of the patterned layers of high stress material. Further, the mobility of the carriers is enhanced, so that the output characteristic of the transistors can be improved.
    • 提供一种制造半导体器件的方法。 该方法主要包括以下步骤:在硅衬底下方形成至少一个第一图案化的高应力层,然后在衬底上形成半导体器件,并在半导体器件上形成至少一个第二图案化的高应力层。 根据该方法,通过利用高应力材料的图案化层的应力,可以同时改善形成在同一晶片上的PMOS和NMOS晶体管的特性。 此外,载流子的迁移率增强,从而可以提高晶体管的输出特性。
