    摘要: In one aspect, there is provided a method of manufacturing a semiconductor device. The method comprises depositing a barrier layer over a low-k dielectric layer located over a semiconductor substrate over which a metal layer is deposited. A chemical mechanical polish process is used to remove a portion of the metal layer and the barrier layer and a dry etch is used to remove a remaining portion of the barrier layer.

    摘要: A method is disclosed for eliminating a mask layer during the manufacture of thin film resistor circuits. The method of the present invention enables the simultaneous etching of both deep vias and shallow vias using one mask layer instead of two mask layers. A high selectivity film layer of silicon nitride is formed on the ends of a thin film resistor layer. The thickness of the silicon nitride causes the etch time for a shallow via to the thin film resistor to be approximately equal to an etch time for a deep via that is etched through dielectric material to an underlying patterned metal layer.
