Abstract: A method of fabricating a dual damascene structure is described. A dielectric layer and a metal hard mask layer are sequentially formed on a substrate having thereon a conductive layer and a liner layer. The metal hard mask layer and the dielectric layer are patterned to form a via hole exposing a portion of the liner layer. A gap-filling layer is filled in the via hole, having a height of ¼ to ½ of the depth of the via hole. A trench is formed in the metal hard mask layer and the dielectric layer. The gap-filling layer is removed to expose the portion of the liner layer, which is then removed. A metal layer is formed filling in the via hole and the trench, and then the metal hard mask layer is removed.

Abstract: A method of fabricating an anti-fuse includes firstly forming a dielectric layer on a substrate having a first conductive type. Next, a conductive layer is formed on the dielectric layer. A first ion implantation process is then performed, such that the conductive layer has the first conductive type. Thereafter, the conductive layer and the dielectric layer are patterned to form a gate and a gate dielectric layer. The gate and the gate dielectric layer together construct a gate structure. Finally, two source/drain regions having a second conductive type are formed in the substrate at respective sides of the gate. Besides, a method of programming an anti-fuse includes firstly applying a voltage to a gate to break down a gate dielectric layer. The gate and a substrate are then electrically conducted or a P/N forward bias is then formed in a P/N junction after the breakdown of the gate dielectric layer.

Abstract: An anti-fuse is provided. The anti-fuse includes a substrate, a gate disposed over the substrate, a gate dielectric layer sandwiched between the substrate and the gate, and two source/drain regions in the substrate at respective sides of the gate. The gate and the substrate have the same conductive type, but the conductive type of the gate and the substrate is different from that of the two source/drain regions.

Abstract: An anti-fuse is formed with a transistor with a doped channel. The anti-fuse will not generate a non-linear current after the anti-fuse is blown. The anti-fuse is used in memory cells of one-time programmable (OTP) memory. The OTP memory utilizes a p-type transistor and an n-type transistor to program the anti-fuse. The anti-fuse has the doped channel, so a current will not flow through the p/n junction between the substrate and two doped regions of the anti-fuse to form a non-linear current after the anti-fuse is blown. Thus, the memory cells of the OTP memory can be programmed correctly.
