The semiconductor device includes a resistance-reduced transistor with metallized bilayer overlying source/drain regions and gate electrode thereof. A first dielectric layer with a conductive contact overlies the resistance-reduced transistor. A second dielectric layer having a first conductive feature overlies the first dielectric layer. A third dielectric layer with a second conductive feature overlies the second dielectric layer, forming a conductive pathway down to the top surface of the metallized bilayer over one of the source/drain regions or the gate electrode layer.

    摘要: A semiconductor interconnect structure includes an organic and/or photosensitive etch buffer layer disposed over a contact surface. The structure further provides an interlevel dielectric formed over the etch buffer layer. A method for forming an interconnect structure includes etching to form an opening in the interlevel dielectric, the etching operation being terminated at or above the etch buffer layer. The etch buffer layer is removed to expose the contact surface using a removal process that may include wet etching, ashing or DUV exposure followed by developing or other techniques that do not result in damage to contact surface. The contact surface may be a conductive material such as silicide, salicide or a metal alloy.

    摘要: A method of forming an opening on a low-k dielectric layer using a polysilicon hard mask rather than a metal hard mask as used in prior art. A polysilicon hard mask is formed over a low-k dielectric layer and a photoresist layer is formed over the polysilicon hard mask. The photoresist layer is patterned and the polysilicon hard mask is etched with a gas plasma to create exposed portions of the low-k dielectric layer. The photoresist layer in stripped prior to the etching of the exposed portions of the low-k dielectric layer to avoid damage to the low-k dielectric layer.
