    • A method for etching a silicon layer within a microelectronics fabrication. There is first provided a substrate employed within a microelectronics fabrication. There is then formed over the substrate a blanket silicon layer. There is then formed upon the blanket silicon layer a blanket silicon containing hard mask layer, where the blanket silicon containing hard mask layer is formed from a silicon containing material chosen from the group of silicon containing materials consisting of silicon oxide materials, silicon nitride materials, silicon oxynitride materials and composites of silicon oxide materials, silicon nitride materials and silicon oxynitride materials. There is then formed upon the blanket silicon containing hard mask layer a patterned photoresist layer. There is then etched through a first plasma etch method the blanket silicon containing hard mask layer to form a patterned silicon containing hard mask layer while employing the patterned photoresist layer as a first etch mask layer. The first plasma etch method employs a first etchant gas composition comprising a first fluorine and carbon containing etchant source gas and a first bromine containing etchant source gas. Finally, there is then etched in-situ through a second plasma etch method the blanket silicon layer to form an at least partially etched silicon layer while employing the patterned photoresist layer and the patterned silicon containing hard mask layer as a second etch mask. The second plasma etch method employs a second etchant gas composition comprising a second fluorine and carbon containing etchant source gas, a second bromine containing etchant source gas and a chlorine containing etchant source gas.
    • 一种在微电子制造中蚀刻硅层的方法。 首先提供了在微电子制造中使用的衬底。 然后在衬底上形成覆盖硅层。 然后在橡皮布硅层上形成含有覆盖硅的硬掩模层,其中,含硅的硬掩模层由含硅材料形成,所述含硅材料选自由硅氧化物材料,氮化硅材料, 氮氧化硅材料和氧化硅材料,氮化硅材料和氮氧化硅材料的复合材料。 然后在橡皮布含硅的硬掩模层上形成图案化的光致抗蚀剂层。 然后通过第一等离子体蚀刻方法蚀刻包含硅的硬掩模层,以形成图案化的含硅硬掩模层,同时使用图案化的光致抗蚀剂层作为第一蚀刻掩模层。 第一等离子体蚀刻方法采用包含第一含氟和碳的蚀刻剂源气体和第一含溴腐蚀剂源气体的第一蚀刻剂气体组合物。 最后,然后通过第二等离子体蚀刻方法将橡皮布硅层原位蚀刻以形成至少部分蚀刻的硅层,同时使用图案化的光致抗蚀剂层和图案化的含硅硬掩模层作为第二蚀刻掩模。 第二等离子体蚀刻方法采用包含第二含氟和碳的蚀刻剂源气体的第二蚀刻剂气体组合物,第二含溴蚀刻剂源气体和含氯腐蚀剂源气体。
