    • In damascene process integration, a reducing plasma is applied after the etch stop or barrier layer is opened over a copper layer. Currently known methods for opening barrier layers suffer from the disadvantage that they cause at least some of the underlying copper to oxidize to copper oxide.. Because copper oxide is selectively removed by subsequent wet cleaning, voids can form where damaged copper (e.g., copper oxide) is removed, thus compromising the reliability of metal-to-metal contact in vias. The present invention advantageously overcomes this and other disadvantages of the prior art through the use of a hydrogen plasma following the barrier layer opening step, which repairs damaged copper (e.g., reduces copper oxide to copper), thus preventing and/or diminishing defects in metal-to-metal contacts in vias and concomitantly improving the reliability of the same.
    • 在镶嵌工艺集成中,在蚀刻停止或阻挡层在铜层上打开之后施加还原等离子体。 目前已知的用于打开阻挡层的方法的缺点在于它们使至少一些下面的铜氧化成氧化铜。由于通过随后的湿法清洁选择性地除去氧化铜,所以在损坏的铜(例如,氧化铜 ),因此损害了通孔中金属对金属接触的可靠性。 本发明有利地通过在阻挡层开口步骤之后使用氢等离子体来克服现有技术的这个和其他缺点,其修复损坏的铜(例如,将铜氧化物还原为铜),从而防止和/或减少金属中的缺陷 金属触点,同时提高了其可靠性。

    • Pitch multiplied and non-pitch multiplied features of an integrated circuit, e.g., features in the array, interface and periphery areas of the integrated circuit, are formed by processing a substrate through a mask. The mask is formed by patterning a photoresist layer which simultaneously defines mask elements corresponding to features in the array, interface and periphery areas of the integrated circuit. The pattern is transferred to an amorphous carbon layer. Sidewall spacers are formed on the sidewalls of the patterned amorphous carbon layer. A layer of protective material is deposited and then patterned to expose mask elements in the array region and in selected parts of the interface or periphery areas. Amorphous carbon in the array region or other exposed parts is removed, thereby leaving a pattern including free-standing, pitch multiplied spacers in the array region. The protective material is removed, leaving a pattern of pitch multiplied spacers in the array region and non-pitch multiplied mask elements in the interface and periphery areas. The pattern is transferred to a hard mask layer, through which an underlying substrate is etched.
    • 通过通过掩模处理衬底来形成集成电路的间距倍增和非间距倍数特征,例如集成电路的阵列,接口和外围区域中的特征。 通过图案化光刻胶层来形成掩模,该光致抗蚀剂层同时限定对应于集成电路的阵列,界面和外围区域中的特征的掩模元件。 将图案转移到无定形碳层。 侧壁间隔物形成在图案化无定形碳层的侧壁上。 沉积一层保护材料,然后将其图案化以暴露阵列区域中的掩模元件和界面或外围区域的选定部分。 除去阵列区域或其它暴露部分中的无定形碳,从而在阵列区域中留下包括独立的,间距倍增的间隔物的图案。 去除保护材料,在阵列区域中留下间距倍数间隔物的图案,并在界面和外围区域留下非间距倍增的掩模元件。 将图案转移到硬掩模层,通过该硬掩模层蚀刻下面的基底。

    • An assembly for sealing a front door and a rear door in a door opening on a vehicle lacking a conventional, separate B-pillar. The front door carries an adaptor at a lower rear end thereof that defines a generally sharp corner over which a portion of the front door seal extends. The rear door defines a sealing surface that is engaged by the portion of the front door seal extending over the adaptor. The rear door includes a rear door seal, a portion of which extends over an outer surface of the rear door and is engaged a sealing surface provided by the front door. At least a portion of the rear door seal and sealing surface are integrally formed by a sealing boot disposed over a lower end of the rear door so as to create a seal-to-seal type engagement between the front and rear doors.
