  • Patent number: 7605064
    Abstract: A method of manufacture for semiconductor electronic products and a circuit structure. A semiconductor material has a surface region and dopant is provided to a portion of the surface region. The portion of the surface region provided with the dopant is irradiated with sufficient energy to induce diffusion of the dopant from the portion of the surface region to another region of the semiconductor material. A method for manufacturing an electronic product with a semiconductor material having a surface and two spaced-apart regions along the surface for receiving dopant includes forming a field effect transistor gate structure is along the surface and over a third region of the surface between the two spaced-apart regions. Dopant is provided to the spaced-apart regions which are heated to a temperature at least 50 degrees C. higher than the peak temperature which results in the third region when the spaced-apart regions are heated.

  • Patent number: 6174807
    Abstract: A method of forming a multi-layered dual-doped polysilicon structure that minimizes Boron penetration into the n+ polysilicon during formation of the p+ polysilicon. The method of the present invention also reduces the migration of Boron (p+ gate dopant) from the p+ polysilicon and the migration of Arsenic and/or Phosphorous (n+ gate dopant) from the n+ polysilicon during subsequent fabrication processing steps. The present invention is also directed to a semiconductor device having a gate dopant barrier that minimizes gate dopant penetration and migration.

  • Patent number: 5851870
    Abstract: A novel capacitor design for use in semiconductor integrated circuits is disclosed. The capacitor includes a metal-dielectric-metal stack formed within a window and upon a conductive substrate. Contact to the top plate of the capacitor is through a window within a window, while contact to the bottom plate is achieved by a guard ring which contacts the conductive substrate.

  • Patent number: 5825073
    Abstract: A method for making a metal-to-metal capacitor for an integrated circuit includes forming a layer of titanium/titanium nitride on a polysilicon which has been patterned with interlevel dielectrics. A capacitor dielectric is then deposited, followed by patterning with photoresist to delineate the capacitor, etching to remove extraneous dielectric, deposition of aluminum, further patterning and etching to define the capacitor and access area, and removal of photoresist.

  • Patent number: 5654581
    Abstract: An integrated circuit with a capacitor includes a conductive substrate, a layer of field dielectric formed on the conductive substrate, a layer of conductive metal or conductive polycrystalline silicon formed on the field dielectric, and first and second laterally spaced apart layers of conductive material formed on the conductive metal or polycrystalline silicon. Each spaced apart layer preferably includes a layer of titanium nitride disposed over a layer of titanium. A layer of capacitor dielectric is deposited on the first of the spaced apart layers, and metal is deposited over the capacitor dielectric and the second layer of conductive material.
