  • Patent number: 6653674
    Abstract: A semiconductor device is provided having angled dopant implantation and vertical trenches in the silicon on insulator substrate adjacent to the sides of a semiconductor gate. A second dopant implantation is in the exposed the source/drain junctions. Contacts having inwardly curved cross-sectional widths in the semiconductor substrate connect vertically to the exposed source/drain junctions either directly or through salicided contact areas.
    Type: Grant

  • Publication number: 20020151108
    Abstract: A semiconductor device and manufacturing process therefor is provided in which angled dopant implantation is followed by the formation of vertical trenches in the silicon on insulator substrate adjacent to the sides of the semiconductor gate. A second dopant implantation in the exposed the source/drain junctions is followed by a rapid thermal anneal that forms the semiconductor channel in the substrate. Contacts having inwardly curved cross-sectional widths in the semiconductor substrate are then formed which connect vertically to the exposed source/drain junctions either directly or through salicided contact areas.

  • Patent number: 6329253
    Abstract: A method for forming a novel thick oxide electrostatic discharge device using shallow trench isolation technology is described. A trench is etched into a semiconductor substrate. An oxide layer is deposited overlying the semiconductor substrate and filling the trench. The oxide within the trench is partially etched away leaving the oxide on the sidewalls and bottom of the trench. The oxide is polished away to the surface of the semiconductor substrate whereby oxide remains only on the sidewalls and bottom of the trench. A gate is formed within the trench whereby the gate is surrounded by the oxide. First ions are implanted into the semiconductor substrate adjacent to the trench to form N-wells. Second ions are implanted into the semiconductor substrate in a top portion of the N-wells to form source/drain regions. Third ions are implanted into the semiconductor substrate underlying the N-wells and underlying the trench to form electrostatic discharge trigger taps.

  • Patent number: 6284609
    Abstract: A new method of fabricating a sub-quarter micron MOSFET device is achieved. A semiconductor substrate is provided. Isolation regions are formed in this substrate. An oxide layer is provided overlying both the substrate and the isolation regions. The oxide layer is patterned and etched exposing two regions of the substrate. A selective epitaxial growth (SEG) is performed with in situ doping covering the two exposed substrate regions formed during the previous step. The doped SEG regions will form the source and drain contact regions of the MOSFET. The oxide layer region between the two doped SEG regions is then patterned and etched away exposing the substrate. This is followed by a gate oxide formation and either a polysilicon or metal gate deposition. Planarization is then performed on the surface to facilitate interconnection later in the process and to form the final gate structure.

  • Patent number: 6261917
    Abstract: A method for fabricating a metal-oxide-metal capacitor is described. A first insulating layer is provided overlying a semiconductor substrate. A barrier metal layer and a first metal layer are deposited over the insulating layer. A titanium layer is deposited overlying the first metal layer. The titanium layer is exposed to an oxidizing plasma while simultaneously a portion of the titanium layer where the metal-oxide-metal capacitor is to be formed is exposed to light whereby the portion of the titanium layer exposed to light reacts with the oxidizing plasma to form titanium oxide. Thereafter, the titanium layer is removed, leaving the titanium oxide layer where the metal-oxide-metal capacitor is to be formed. A second metal layer is deposited overlying the first metal layer and the titanium oxide layer.

  • Patent number: 6248618
    Abstract: A method of forming thick and thin gate oxides comprising the following steps. A silicon semiconductor substrate having first and second active areas separated by shallow isolation trench regions is provided. Oxide growth is selectively formed over the first active area by UV oxidation to form a first gate oxide layer having a first predetermined thickness. The first and second active areas are then simultaneously oxidized whereby the first predetermined thickness of the first gate oxide layer is increased to a second predetermined thickness and a second gate oxide layer having a predetermined thickness is formed in the second active area. The second predetermined thickness of the first oxide layer in the first active area is greater than the predetermined thickness of the second oxide layer in the second active area.
