    • An electrical fuse and a first dielectric layer thereupon are formed on a semiconductor substrate. Self-assembling block copolymers containing two or more different polymeric block components are applied into a recessed region surrounded by a dielectric template layer. The self-assembling block copolymers are then annealed to form a pattern of multiple circles having a sublithographic diameter. The pattern of multiple circles is transferred into the first dielectric layer by a reactive ion etch, wherein the portion of the first dielectric layer above the fuselink has a honeycomb pattern comprising multiple circular cylindrical holes. A second dielectric layer is formed over the circular cylindrical holes by a non-conformal chemical vapor deposition and sublithographic cavities are formed on the fuselink. The sublithographic cavities provide enhanced thermal insulation relative to dielectric materials to the fuselink so that the electrical fuse may be programmed with less programming current.
    • 在半导体衬底上形成电熔丝和第一电介质层。 含有两个或更多个不同聚合物嵌段组分的自组装嵌段共聚物被施加到由电介质模板层包围的凹陷区域中。 然后将自组装嵌段共聚物退火以形成具有亚光刻直径的多个圆的图案。 通过反应离子蚀刻将多个圆圈的图案转移到第一介电层中,其中,在熔体上方的第一介电层的部分具有包括多个圆柱形孔的蜂窝图案。 通过非共形化学气相沉积在圆柱形孔上方形成第二介电层,并在融合体上形成亚光刻腔。 亚光刻腔相对于介质材料提供与熔丝相关的增强的热绝缘,使得电熔丝可以用较少的编程电流编程。
