    • Methods of etching high-aspect-ratio features in dielectric materials such as silicon oxide are described. The methods may include a concurrent introduction of a fluorocarbon precursor and an iodo-fluorocarbon precursor into a substrate processing system housing a substrate. The fluorocarbon precursor may have a F:C atomic ratio of about 2:1 or less, and the iodo-fluorocarbon may have a F:C ratio of about 1.75:1 to about 1.5:1. Exemplary precursors may include C4F6, C5F8 and C2F3I, among others. The substrate processing system may be configured to allow creation of a plasma useful for accelerating ions created in the plasma toward the substrate. The substrate may have regions of exposed silicon oxide and an overlying patterned photoresist layer which exposes narrow regions of silicon oxide. The etch process may remove the silicon oxide to a significant depth while maintaining a relatively constant width down the trench.
    • 描述了蚀刻介电材料如氧化硅中的高纵横比特征的方法。 所述方法可以包括将碳氟前体和碘 - 碳氟化合物前体同时引入到容纳衬底的衬底处理系统中。 碳氟化合物前体可以具有约2:1或更低的F:C原子比,并且碘代氟碳可以具有约1.75:1至约1.5:1的F:C比。 示例性前体可以包括C4F6,C5F8和C2F3I等。 衬底处理系统可以被配置为允许产生用于将在等离子体中产生的离子加速到衬底的等离子体。 衬底可以具有暴露的氧化硅的区域和暴露氧化硅的窄区域的上覆图案化的光刻胶层。 蚀刻工艺可以将氧化硅移除到显着的深度,同时保持沟槽相对恒定的宽度。

    • A system (10) for laminating a plurality of veneer layers (14, 18) is disclosed. The system (10) comprises a base veneer layer roll (12) carrying a base veneer layer (14) and at least one additional roll (16) carrying at least one additional veneer layer (18) that is to be laminated to the base veneer layer (14). Guiding means (24, 28) is provided for guiding the two layers (14, 18) towards each other, with a pair of adjacent laminating rollers (30, 32) being arranged to receive the base veneer layer (14) and the additional veneer layer (18) therebetween, so as to continuously laminate the two layers (14, 18) as they move through the laminating rollers (30, 32). Preferably, the additional veneer layer (18) is impregnated with heat-activatable glue, with the system (10) further including a bank of heating elements (40) arranged to activate the glue on the additional veneer layer (18).
    • 公开了一种用于层叠多个单板层(14,18)的系统(10)。 系统(10)包括承载底部单板层(14)的基底单板层辊(12)和至少一个另外的辊(16),所述至少一个附加辊承载至少一个另外的薄板层(18) 层(14)。 提供引导装置(24,28),用于将两层(14,18)彼此引导,一对相邻的层压辊(30,32)被布置成接收底层单板层(14)和附加单板 层(18,18),以便当它们移动通过层压辊(30,32)时,使两层(14,18)连续层压。 优选地,附加的薄板层(18)浸渍有可热激活的胶水,系统(10)还包括一组加热元件(40),其被布置成激活附加单板层(18)上的胶水。
