    • A planar interconnect using selective deposition of a refractory metal such as tungsten into oxide channels is disclosed. A layer of silicon dioxide as thick as the desired tungsten interconnect is placed on the surface of a substrate such as an integrated circuit wafer. Thereafter, a layer of silicon nitride about 100 nm thick is formed on the silicon dioxide. Channels are formed in the silicon dioxide by patterning and etching the composite dielectric layers. After the photoresist is removed, silicon or tungsten atoms at 40 KeV are implanted in the silicon dioxide channels, the silicon nitride acting as a mask. Typically, a dosage as high as 1.times.10.sup.17 cm.sup.-2 is used. The silicon or tungsten implant allows seeding of the tungsten or other refractory metal. The silicon nitride mask is selectively removed by a hot phosphoric acid solution, and a metal film is then selectively deposited to fill the channels in the silicon dioxide layer, which then forms a level of interconnects. The process is repeated to form vias and subsequent levels of interconnects.
    • 公开了使用将难熔金属如钨选择性沉积到氧化物通道中的平面互连。 将诸如所需钨互连的厚度的二氧化硅层放置在诸如集成电路晶片的衬底的表面上。 此后,在二氧化硅上形成约100nm厚的氮化硅层。 通过图案化和蚀刻复合电介质层,在二氧化硅中形成沟道。 在除去光致抗蚀剂之后,将40KeV的硅或钨原子注入到二氧化硅通道中,氮化硅用作掩模。 通常,使用高达1×10 17 cm -2的剂量。 硅或钨植入物允许接合钨或其它难熔金属。 通过热磷酸溶液选择性地除去氮化硅掩模,然后选择性地沉积金属膜以填充二氧化硅层中的通道,然后形成一定程度的互连。 重复该过程以形成通孔和随后的互连级别。
