    • A method of fabricating semiconductor devices using dual damascene processes to form plugs in the via holes composed of various high etch materials and bottom anti-reflection coating (BARC) materials. After via hole etch, a layer of high etch rate plug material is spin coated to fill the via holes. Next, a layer of photoresist is applied. The photoresist is then exposed through a mask and developed to form an etch opening. Using the remaining photoresist as an etch mask and with a bottom anti-reflection coating (BARC) as protection, the oxide or low k layer is etched to form subsequent wiring. The etch step is known as a damascene etch step. The remaining photoresist is removed and the trench/via openings are filled with metal forming inlaid metal interconnect wiring and contact vias.
    • 使用双镶嵌工艺制造半导体器件的方法来在由各种高蚀刻材料和底部抗反射涂层(BARC)材料组成的通孔中形成插塞。 在通孔蚀刻之后,旋涂一层高蚀刻速率的塞材料以填充通孔。 接下来,施加一层光致抗蚀剂。 然后将光致抗蚀剂通过掩模曝光并显影以形成蚀刻开口。 使用剩余的光致抗蚀剂作为蚀刻掩模和底部防反射涂层(BARC)作为保护,氧化物或低k层被蚀刻以形成后续布线。 蚀刻步骤被称为镶嵌蚀刻步骤。 去除剩余的光致抗蚀剂,并且通过金属形成金属互连布线和接触通孔填充沟槽/通孔开口。

    • A plasma etch process for organic low-k dielectric layers using NH3 only, or NH3/H2 or NH3/H2 gases. A low k dielectric layer is formed over a substrate. A masking pattern is formed over the low k dielectric layer. The masking pattern has an opening. Using the invention's etch process, the low k dielectric layer is etched through the opening using the masking pattern as an etch mask. In a first embodiment, the etch process comprises: etching the low k dielectric layer by applying a plasma power and flowing only NH3 gas. In a second embodiment, the etch process comprises: etching the low k dielectric layer by applying a plasma power and flowing only NH3/H2 gas. In a third embodiment, the etch process comprises: etching the low k dielectric layer by applying a plasma power and flowing only NH3/N2 gas. The invention's NH3 containing plasma etch etches organic Low k materials unexpectedly fast. The invention's NH3 only etch had a 30 to 80% high etch rate than N2/H2 etches of low-k materials like Silk™.
