    摘要: Polysilicon (20) in a trench (21) is etched at an angle to produce a conductor within the trench that has shape characteristics which approximate the shadow of the side wall (26) of the trench (21) closest the beam source. Specifically, when the first side wall (26) is closest the beam source and the second side wall (27) is furthest from the beam source, the polysilicon on the first side wall (26) is almost as high as the first side wall (26), while the polysilicon on the more exposed side wall (27) is considerably lower than the first side wall (26) and approximates the shadow of the first side wall (26) on the second side wall (27) relative to the beam. The polysilicon (20) in the trench (21) may be in the shape of a solid angled block approximating the shadow line from the top of side wall (26) to side wall (27); however, it is preferred that the polysilicon take the form of a conformal layer in trench (21) prior to etching such that the polysilicon ultimately has an angled "U" shape which approximates the shadow line. Contact is made to the polysilicon (20) using strap (23) that electrically connects the side wall (26) with the polysilicon (20). Strap (23) is sized such that it does not extend to the opposite side wall (27) of trench (21), thereby avoiding short circuits. Having the polysilicon (20) approximate the shadow line of the etch permits narrowing the distance between adjacent straps (23) and (24) in an array without the risk of creating a short circuit.

    摘要: A process for forming a thin film on a surface of a semiconductor device. The process involves formation of a silicon dioxide film by plasma enhanced thermal oxidation, employing a mixture of ozone and oxygen which are generated separately from the reactor chamber in a volume ratio of about 1-10/1, preferably about 5-7/1, at a temperature generally below 440.degree. C., preferably about 350.degree.-400.degree. C. The process is used to form sidewall oxide spacers on polysilicon gates for field effect transistors. A relatively fast oxidation rate is achieved at a temperature significantly below that employed in conventional oxidation processes, and this serves to reduce dopant diffusion from the polysilicon. In addition, the resulting film demonstrates low stress with good conformal step coverage of the polysilicon gates. Another use of the process is to grow thin gate oxides and oxide-nitride-oxide with a thickness of less than 100.ANG.. An oxide film of uniform thickness is formed by controlling the temperature, RF power, exposure time and oxygen/ozone ratio for thin gate oxide (

The inventive dielectric cap includes a multilayered dielectric material stack wherein at least one layer of the stack has good oxidation resistance, Cu diffusion and/or substantially higher mechanical stability during a post-deposition curing treatment, and including Si—N bonds at the interface of a conductive material such as, for example, Cu.

    摘要: A programmable structure such as a write once read many (WORM) or one time programmable read only memories (OTPROM) is disclosed herein. The structure includes a first conductor (such as copper) positioned within a substrate and a metal cap on the first conductor. A low-k dielectric is on the substrate and the metal cap. A tantalum nitride resistor is on the dielectric, and the resistor is positioned above the metal cap such that a programmable region of the dielectric is positioned between the resistor and the metal cap. The first conductor (including the metal cap), the programmable region of the dielectric, and the resistor form a metal-insulator-metal capacitor. Further, the programmable region of the dielectric is adapted to be permanently changed from heat produced by the resistor when a voltage difference is applied to the first and second ends of the resistor, respectively, through the first and second contacts. Thus, the capacitor comprises a first capacitance before the programmable region is permanently changed by the heat from the resistor and comprises a second capacitance after the programmable region is permanently changed by the heat from the resistor.
