    • A BARC or other sacrificial fill layer etch comprises a selective etch chemistry of Ar/O2/CO. The BARC etch may be used in a via-first dual damascene method. After via (116) pattern and etch, a BARC/sacrificial fill layer (120) is deposited to fill the via (116) and coat the IMD (110). The excess sacrificial fill layer (120) material over the IMD (110) is removed using the Ar/O2/CO etch. A trench resist pattern (125) is formed over the BARC layer (120). During the main trench etch, portions of sacrificial fill layer (120) remain in the via to protect the etch-stop (104) at the bottom of the via (116).
    • BARC或其他牺牲填充层蚀刻包括Ar / O 2 / CO的选择性蚀刻化学。 BARC蚀刻可以以通孔 - 第一双镶嵌方法使用。 在经过(116)图案和蚀刻之后,沉积BARC /牺牲填充层(120)以填充通孔(116)并涂覆IMD(110)。 使用Ar / O 2 / CO蚀刻去除IMD(110)上的多余牺牲填充层(120)材料。 在BARC层(120)之上形成沟槽抗蚀剂图案(125)。 在主沟槽蚀刻期间,牺牲填充层(120)的部分保留在通孔中,以保护通孔(116)底部的蚀刻停止(104)。

    • Data representing application deployment attributes, network topology, and network performance attributes based on a reduced set of element attributes is utilized to simulate application deployment. The data may be received from a user directly, a program that models a network topology or application behavior, and a wizard that implies the data based on an interview process. The simulation may be based on application deployment attributes including application traffic pattern, application message sizes, network topology, and network performance attributes. The element attributes may be determined from a lookup table of element operating characteristics that may contain element maximum and minimum boundary operating values utilized to interpolate other operating conditions. Application response time may be derived using an iterative analysis based on multiple instances of one or more applications wherein a predetermined number of iterations is used or until a substantially steady state of network performance is achieved.

    • A spin-on dielectric (120) strip process. Instead of a wet strip, a dry strip process is used to remove the spin-on dielectric (120). In a via-first dual damascene method, a via (116) may be patterned and etched and the via (116) is filled with the spin-on dielectric (120). Then, the trench is patterned and etched while the spin-on dielectric (120) protects the bottom of the via (116). Finally, the spin-on dielectric (120) is removed using a dry strip process with a low ion energy plasma.

    • A method includes performing a first etch process to form a via hole in a dual-damascene integrated circuit structure comprising a first dielectric layer and a second dielectric layer. The via hole extends at least substantially through the first and second dielectric layers. The method further includes filling at least a portion of the via hole with a plug material to form a plug within the via hole, and performing a second etch process through the first dielectric layer and the portion of the plug adjacent the first dielectric layer to form a trench in the first dielectric layer. The second etch process is performed using an RF power of less than 1,000 Watts and using an etching chemistry that includes CF4 and N2. For example, second etch process may use an etching chemistry of CF4/N2/Ar, which may additionally include one or both of CO and O2.
