    • An integrated circuit is formed with structures spaced more closely together than a transverse dimension of such structures, such as for making contacts to electronic elements formed at minimum lithographically resolvable dimensions by dark field split pitch techniques. Acceptable overlay accuracy and process efficiency and throughput for the split pitch process that requires etching of a hard mark for each of a plurality of sequentially applied and patterned resist layers is supported by performing the etching of the hard mask entirely within a lithography track through using an acid sensitive hard mark material and an acidic overcoat which contacts areas of the hard mask through patterned apertures in the resist. The contacted areas of the hard mask are activated for development by baking of the acidic overcoat.
    • 集成电路形成为具有比这种结构的横向尺寸更紧密地在一起的结构,例如用于通过暗场分割俯仰技术以最小可光滑分辨尺寸形成的电子元件的接触。 对于需要蚀刻多个顺序施加的和图案化的抗蚀剂层中的每一个的硬标记的分割间距处理的可接受的覆盖精度和处理效率和处理量通过使用 酸敏感的硬标记材料和通过抗蚀剂中的图案化孔接触硬掩模的区域的酸性外涂层。 通过烘烤酸性外涂层来激活硬掩模的接触区域以进行显影。

    • The circuit structure includes at least two generally parallel conductor structures, and a plurality of substantially horizontal layers of layer dielectric material interspersed with substantially horizontally extending relatively low dielectric constant (low-k) volumes. The substantially horizontal layers and the substantially horizontally extending volumes are generally interposed between the at least two generally parallel conductor structures. Also included are a plurality of substantially vertically extending relatively low-k volumes sealed within the substantially horizontal layers and the substantially horizontally extending volumes between the at least two generally parallel conductor structures. The substantially vertically extending relatively low-k volumes and the substantially horizontally extending relatively low-k volumes reduce parasitic capacitance between the at least two generally parallel conductor structures as compared to an otherwise comparable microelectronic circuit not including the relatively low-k volumes.
    • 电路结构包括至少两个大致平行的导体结构,以及多个基本上水平的层介质材料层,散布着基本上水平延伸的相对较低的介电常数(低k)体积。 基本水平的层和基本上水平延伸的体积通常介于至少两个大致平行的导体结构之间。 还包括在基本水平的层内密封的多个基本上垂直延伸的相对低k的体积,以及在至少两个大致平行的导体结构之间的基本水平延伸的体积。 与不包括相对低k体积的其他可比较的微电子电路相比,基本垂直延伸的相对低k体积和基本水平延伸的相对低k体积减小了至少两个大致平行的导体结构之间的寄生电容。
