    摘要: A method of fabricating kink-effect-free shallow trench isolations is presented in this invention. First, a layer of silicon oxide and a layer of polysilican are sequentially deposited on a substrate, and then shallow trenches are formed, next thermal oxidation is performed to grow a passivation oxide layer on the exposed silicon, and then, a dielectric layer is formed to fill into the shallow trench. Finally, the dielectric layer on the active area is removed by using chemical mechanical polishing and the polysilicon layer provides for the etching end point. The level of shallow trench is higher than the level of active area as soon as stop polishing, because the polysilicon layer is polished faster than dielectric layer. It provides the passivation oxide on the sidewall of shallow trench to form spacers of the active area after removing the polysilicon of active area. It can provide a perfect shallow trench after an oxidation and etching process to avoid the kink effect.

    摘要: A method of fabricating a shallow trench isolation is disclosed. First, a pad oxide layer and a polysilicon layer are formed on a silicon substrate. The pad oxide layer and the polysilicon layer are etched to expose parts of the substrate. Then the exposed parts of the substrate are oxidized to form an oxide layer. Next, the oxide layer is etched back to form an oxide spacer on the side wall of the polysilicon. Then, a shallow trench is formed by etching the partly exposed substrate. Next, a dielectric layer is formed to fill the shallow trench and then etched back by CMP to stop on the polysilicon layer. Finally, the pad oxide layer and the polysilicon layer are removed. As a result, oxide spacers on the side wall of the shallow trench are formed to eliminate the kink-effect.

    摘要: The present invention proposes a method for forming shallow trench isolation. Isolation trenches are firstly formed on a silicon substrate. High-density plasma oxide layer is used to fill the trenches. A layer of poly-silicon and a thin oxide layer are then deposited on the high-density plasma oxide layer. Selective poly-silicon chemical mechanical polishing is then used to form a self-align reverse poly mask on the surface of the shallow trenches filled with the high-density plasma oxide layer. The high-density plasma oxide layer is locally etched. Chemical mechanical polishing is then used to perform a planarization process on the surface. In the present invention, photolithography is not necessary in the planarization process of high-density plasma oxide layer. Manufacture cost is thus lower.

    摘要: A method of forming a trench capacitor is disclosed. After completion of the bottom electrode of the capacitor, a collar dielectric layer is directly formed on the sidewall of the deep trench using self-starved atomic layer chemical vapor deposition (self-starved ALCVD). Then, a high dielectric constant (high k) dielectric layer is formed overlying the collar dielectric and the bottom portion of the deep trench using atomic layer chemical vapor deposition (ALCVD). Thereafter, a conductive layer is filled into the deep trench and recessed to a predetermined depth. A portion of the dielectric layer and the high dielectric constant (high k) layer at the top of the deep trench are removed to complete the fabrication of the deep trench capacitor.
