    Abstract: Described herein is a fuse incorporating a covering layer disposed on a conductive layer, which is disposed on a polysilicon layer. The covering layer preferably comprises a relatively inert material, such as a nitride etchant barrier. The covering layer preferably has a region of relatively less-inert filler material. Upon programming of the fuse, the conductive layer, which can be a silicide, preferentially degrades in the region underlying the filler material of the covering layer. This preferential degradation results in a predictable "blowing" of the fuse in the fuse region underlying the filler material. Since the "blow" area is predictable, damage to adjacent structures can be minimized or eliminated.

    Abstract translation: 这里描述的是一种保险丝，其包括设置在多晶硅层上的导电层上的覆盖层。 覆盖层优选地包括相对惰性的材料，例如氮化物蚀刻剂屏障。 覆盖层优选具有相对较少惰性填料的区域。 在对熔丝进行编程时，可以是硅化物的导电层优选在覆盖层的填充材料下方的区域中降解。 这种优先的劣化导致在填充材料下面的保险丝区域中的可预见的“熔断”熔丝。 由于“打击”区域是可预测的，所以可以最小化或消除对相邻结构的损坏。

    Abstract: PROBLEM TO BE SOLVED: To obtain technical advantages as a device, system, and method of programming an electric fuse by using a transistor to which an active well bias is imparted.
    SOLUTION: In contrast to being grounded, a transistor (i.e. MOSFET) 33 operates through a well bias to program an electric fuse 31. With respect to the programming transistor operated by the active well bias, the fuse 31 can be programmed by the larger energy than that in the case of utilizing in the well with the transistor of the same size grounded. Thus, the smaller transistor can be used for programming the fuse 31. In the enforcement of a plurality of fuses, the programming transistor can be arranged in the same "well" in such a state that the common independent V
    bias is imparted to the entire well through a body controlling circuit 37, while programming the selected fuse 31.

    Abstract: A method forms an anti-fuse structure comprises a plurality of parallel conductive fins positioned on a substrate, each of the fins has a first end and a second end. A second electrical conductor is electrically connected to the second end of the fins. An insulator covers the first end of the fins and a first electrical conductor is positioned on the insulator. The first electrical conductor is electrically insulated from the first end of the fins by the insulator. The insulator is formed to a thickness sufficient to break down on the application of a predetermined voltage between the second electrical conductor and the first electrical conductor and thereby form an uninterrupted electrical connection between the second electrical conductor and the first electrical conductor through the fins.
