    摘要: A method for fabricating interconnects is provided. The method comprises forming a conducting line on a first dielectric layer; forming a first liner layer on the surfaces of the first dielectric layer and the conducting line; forming a second liner layer on the first liner layer; forming a second dielectric layer on the second liner layer, wherein the etching selectivity rate of the second dielectric layer is higher than the etching selectivity rate of the second liner; and patterning the second dielectric layer to form a contact window opening through the second liner layer and the first liner layer to expose the surface of the conducting line. Because the second dielectric layer having an etching rate higher than the etching rate of the second liner layer, the second liner layer can be used as an etch stop layer while patterning the second dielectric layer.

    摘要: A method for forming a self-aligned contact on a semiconductor substrate provided with a plurality of field-effect transistors. The method comprises the steps of: forming a thin nitride insulating layer on a gate structure and a diffusion region of the transistor; forming a first insulating layer, which is then planarized to expose the nitride insulating layer on the gate structure; etching through the first insulating layer to form a first part of a contact hole; forming a first part of a contact in said first part of the contact hole; forming a second insulating layer; etching through the second insulating layer to form a second part of the contact hole; and forming a second part of the contact in the second part of the contact hole. The two-stage etching process for forming a conductive contact effectively prevents over-etching and short-circuiting between a wordline and a bitline.
