摘要： A method of fabricating an anti-fuse module and dual damascene interconnect structure comprises the following steps. A semiconductor structure having at least two exposed metal lines covered by a first dielectric layer is provided. A first metal line is within an anti-fuse area and a second metal line is within an interconnect area. A first metal via is formed within the first dielectric layer within the anti-fuse area with the first metal via contacting the first metal line. A SiN layer is deposited over the first dielectric layer and the first metal via. The SiN layer is patterned to form at least two openings. A first opening exposes the first metal via, and a second opening exposes a portion of the first dielectric layer above the second metal line. A fusing element layer is deposited and patterned over the patterned SiN layered structure to form a fusing element over the first metal via. Simultaneously, an anti-fuse metal line is formed over the fusing element to form an anti-fuse module within the anti-fuse area, and a dual damascene interconnect is formed over, and contacting with, the second metal line and within the interconnect area.

摘要： A new method is provided for the creation of a resistive load in a semiconductor device whereby the semiconductor device further contains gate electrodes and a capacitor. Field isolation regions separate the active areas; a thin layer of gate oxide is created over these active regions. A first layer of poly is deposited, used for the gate electrode, for the bottom plate of the adjacent capacitor and for the resistor of high ohmic value. The gate poly is doped (in the first layer of poly); optionally the bottom plate of the capacitor can be doped. A dielectric layer is deposited for the dielectric of the capacitor; a second layer of poly is deposited, patterned and etched to form the capacitor top plate. The capacitor (dielectric and bottom plate), poly gates and the load resistor are patterned; the LDD regions for the transistors are created. The (gate, capacitor, resistor) spacers are formed, during and as part of the etch of the gate spacers a resistive spacer (called spacer since it serves to space or separate the two contact points of the resistor) is formed. The source/drain implants for the gate electrodes are performed thereby concurrently performing (self-aligned, due to the resistor spacer) implants for the contact regions of the resistor. All contacts (gate poly, source/drain and two contact points on the resistor) are salicided to achieve lower contact resistance.
