    摘要: A method to integrate MIM capacitors into conductive interconnect levels, with low cost impact, and high yield, reliability and performance than existing integration methods is provided. This is accomplished by recessing a prior level dielectric for MIM capacitor level alignment followed by deposition and patterning of the MIM capacitor films. Specifically, the method includes providing a substrate including a wiring level, the wiring level comprising at least one conductive interconnect formed in a dielectric layer; selectively removing a portion of the dielectric layer to recess the dielectric layer below an upper surface of the at least one conductive interconnect; forming a dielectric stack upon the at least one conductive interconnect and the recessed dielectric layer; and forming a metal-insulator-metal (MIM) capacitor on the dielectric stack. The MIM capacitor includes a bottom plate electrode, a dielectric and a top plate electrode. The bottom and top plate electrodes can comprise the same or different conductive metal.

    摘要: A structure which ensures against deterioration of an underlying silicide layer over which a refractory material layer is deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) is realized by first providing a continuous polysilicon layer prior to the refractory material deposition. The continuous polysilicon layer, preferably no thicker than 50 Å, serves a sacrificial purpose and prevents damage to an underlying silicide layer by blocking interaction between any fluorine and the underlying silicide that is released when the refractory material is formed.

    摘要: A method of forming inter-level contacts or vias between metal layers using a tungsten film deposited into the via using non-collimated sputter deposition. The sputter chamber is configured with a pressure of about 1 mTorr to about 10 mTorr with an inert gas flow of at least at least 25 cm3/min to about 150 cm3/min. Shielding inside the chamber is coated with a material, preferably, aluminum oxide, that promotes adhesion of tungsten to the shielding. An adhesion layer of titanium may be included prior to deposition of the tungsten film. Non-collimated sputter deposition increases the target to substrate distance inside the sputter chamber; reduces the heating effect associated with traditional collimated sputtering; and provides more robust diffusion barriers.

    摘要: Electrical fuses and methods for forming an electrical fuse. The electrical fuse includes a current shunt formed by patterning a first layer comprised of a first conductive material and disposed on a top surface of a dielectric layer. A layer stack is formed on the current shunt and the top surface of the dielectric layer surrounding the current shunt. The layer stack includes a second layer comprised of a second conductive material and a third layer comprised of a third conductive material. The layer stack may be patterned to define a fuse link as a first portion of the layer stack directly contacting the top surface of the dielectric layer and a terminal as a second portion separated from the top surface of the dielectric layer by the current shunt.
