  • Patent number: 6677216
    Abstract: Embodiments of the present invention relate to a method of making an IC capacitor. In one embodiment, the method comprises providing a substrate, forming a polycide layer on the substrate, and forming an insulating amorphous silicon layer on the polycide layer. The insulating amorphous silicon layer serves as an anti-reflection layer. The method further comprises implanting n-type ions into the insulating amorphous silicon layer to transform the insulating amorphous silicon layer into a conductive amorphous silicon layer, and patterning the polycide layer and the conductive amorphous silicon layer to form a bottom electrode on the substrate. A dielectric layer is formed on the bottom electrode and the substrate, and a conductor layer is formed on the dielectric layer. The conductor layer is patterned to form a top electrode on the dielectric layer.

  • Patent number: 6661061
    Abstract: A semiconductor process for producing two gate oxide thicknesses within an integrated circuit in which a semiconductor substrate having a first region and a second region is provided. The first region and the second region are laterally displaced with respect to one another. A nitrogen species impurity distribution is then introduced into the first region of the semiconductor substrate. Thereafter, a gate dielectric layer is grown on an upper surface of the semiconductor substrate. The gate dielectric has a first thickness over the first region of the semiconductor substrate and a second thickness over the second region of the semiconductor substrate. The first thickness is less than the second thickness. In a CMOS embodiment of the present invention, the first region of the semiconductor substrate comprises p-type silicon while the second substrate region comprises n-type silicon.
