    • An antifuse particularly suitable for submicron geometries is presented. The antifuse is formed between a silicon layer, which could be a doped region of the semiconductor substrate, an epitaxial layer or a polysilicon layer, and an upper metal interconnection layer. In contact holes in a silicon dioxide layer insulating the silicon and metal interconnection layers from each other, the antifuses have a thick refractory metal layer having a top surface approximately at the same level as the top surface of the insulating layer. Depending upon the process used to deposit the refractory metal layer, a thin adhesion layer may be located immediately below the refractory metal layer. Between the underlying silicon layer and upper interconnection layer, a thin semiconductor material layer of amorphous silicon may be located either below the refractory metal layer or above it. At its bottom, the interconnection layer also has a barrier layer to prevent any intermixing between the amorphous silicon layer and the metal interconnection layer.
    • 提出了特别适用于亚微米几何形状的反熔丝。 反熔丝形成在可以是半导体衬底的掺杂区域的硅层,外延层或多晶硅层和上部金属互连层之间。 在硅和金属互连层彼此绝缘的二氧化硅层的接触孔中,反熔丝具有厚的难熔金属层,其顶表面与绝缘层的顶表面大致相同。 根据用于沉积难熔金属层的方法,薄的粘合层可以位于难熔金属层的正下方。 在下层硅层和上互连层之间,非晶硅的薄半导体材料层可以位于难熔金属层之下或其上方。 在其底部,互连层还具有阻挡层以防止非晶硅层和金属互连层之间的任何混合。

    • A multi-use variable guard rail system for providing a safe working area is mountable on various surfaces, whether sloped (roofs), vertical (walls) or horizontal (floors). A rail support of the system has an upright pivotally engaged with a base, and a brace that locks the upright relative to the base in numerous positions ranging between an acute angle and an obtuse angle where the upright and base are linearly aligned. The upright has openings that hold rails such as various sizes of lumber in a vertically stacked array without the need to cut or fasten the lumber, and which allows for replacement of rails without disassembly of the rest of the system. The base has a tongue particularly suited for roof work, namely it is used to mount the rail support to the roof, yet allows the base to be lifted for placing shingles thereunder.
    • 用于提供安全工作区域的多用途可变护栏系统可安装在各种表面上,无论是倾斜(屋顶),垂直(墙壁)还是水平(楼层)。 系统的轨道支撑件具有与基座直立枢转地接合的支架,以及支架,其将竖立件相对于基座锁定在倾斜角度和钝角之间的许多位置,其中直立件和底座线性对准。 立柱具有开口,其将诸如各种尺寸的木材的轨道保持在垂直堆叠的阵列中,而不需要切割或紧固木材,并且允许更换轨道而不拆卸系统的其余部分。 基座具有特别适用于屋顶工作的舌头,即用于将导轨支架安装在屋顶上,但允许底座被提升以将其放置在其下。
