    摘要: An apparatus for characterizing capacitance and thickness of an insulating layer constructed between a conductive gate and a substrate has at least one test structure formed at a surface of a substrate. Each test structure has a bulk region formed of a semiconductor within the surface. Further the test structure has at least one source region and one drain region within the bulk region. A thin insulating layer is placed above the each source region, each drain region, and the bulk region. A conductive gate is placed above the thin insulating layer. A capacitance-voltage measuring device measures a capacitance value of the test structure, while forcing the bulk region between the source region and the drain region to be floating. An insulating layer thickness calculator determines the thickness of the insulating layer from the capacitance.

    摘要: A method for improving the planarity of a semiconductor chip using chemical-mechanical polishing during a shallow trench isolation process is described. Specifically, an polish-stop layer, preferably of silicon nitride, is formed over a semiconductor wafer (or optionally formed over a pad oxide layer formed on the wafer). A cap layer, preferably of polysilicon, is then formed over the polish-stop layer. The active regions of the chip are defined, preferably using a photoresist mask by photolithography. The wafer, polish-stop and cap layers are then etched, between the active regions, to form shallow trenches. A lining dielectric layer, preferably an oxide, is formed over the etched and non-etched regions to fill the shallow trenches for isolation purposes. The dielectric layer has an etching rate at least three times greater than the etching rate of cap layer. When polysilicon is selected as the cap layer and oxide is selected as the dielectric layer, the selectivity rate is greater than ten. However, the conventional oxide dielectric/nitride layer etching selectivity rate is less than three. Accordingly, the present invention provides a far greater etching selectivity rate than the prior art. In addition, the polish rate of the cap layer is much higher that that of the polish-stop layer. Therefore, the cap layer can be easily removed which reduces the CMP time while minimizing the dishing effect.
