    摘要: According to the preferred embodiment of the present invention, an improved resistor and method of fabrication is provided. The method for fabricating a resistive element into an integrated circuit semiconductor device comprises the steps of: depositing a dielectric film, such as silicon nitride; depositing a titanium film upon the dielectric film; and annealing the titanium and dielectric films. This causes titanium to be diffused into the dielectric film. This creates a resistive element having a relatively high resistivity. The preferred embodiment method has the advantage of being easily integrated into conventional integrated circuit fabrication techniques.

    摘要: A method of forming interlevel studs in an insulating layer on a semiconductor wafer. First, a conformal BPSG layer is formed on a Front End of the Line (FEOL) semiconductor structure. Vias are opened through the BPSG layer to the FEOL structure. A layer of poly is formed (deposited) on the BPSG layer, filling the vias. The poly layer may be insitu doped poly or implanted after it is deposited. The wafer is annealed to diffuse dopant from the poly to form diffusions wherever the poly contacts the substrate. A non-selective slurry of colloidal silica and at least 1% ammonium hydroxide is used to chem-mech polish the poly from the BPSG layer and, simultaneously, planarize the BPSG layer.
