    Abstract: A method for liquid phase deposition, including the steps of providing at least two raw materials from at least two supply devices of a saturation reaction system into a mixture trough and stirring until saturation occurs, filtering out unnecessary solid-state particles, and providing saturated and filtered liquid into an over-saturation reaction trough of a steady-flow over-saturation loop reaction system and stopping the saturated and filtered liquid when the over-saturation reaction trough is filled and the saturated and filtered liquid over-flows into a liquid level control trough to a pre-determined level. The method also includes the steps of providing a substrate in the over-saturation reaction trough, providing reactants from at least two supply devices into the over-saturation reaction trough, and depositing a thin film onto the substrate when the saturated liquid becomes over-saturated.

    Abstract: A polysilicon transistor having a buried-gate structure is fabricated by a method involving a liquid phase deposition which is used for depositing selectively a silicon dioxide layer on a polysilicon layer, but not on a photoresist layer. The silicon dioxide liquid phase deposition is brought about by using an aqueous hydrofluorosilicic acid (H.sub.2 SiF.sub.6) solution supersaturated with silicon dioxide. Upon completion of the stripping of the photoresist layer, the selectively-deposited silicon dioxide layer is used as a mask to perform the source/drain ion implant.

    Abstract: A method is capable of providing a semiconductor device with a gate having thereon a thicker silicide or metal layer and further having a lower interconnect resistance. The method is further capable of providing the semiconductor device with a polysilicon gate having a recessed tungsten structure for prevention of short circuit between the gate and the drain or the source. For forming a grooved gate structure, a photo-resist is formed on the polysilicon gate before growing on the entire surface of the silicon substrate a silicon dioxide layer. The silicon dioxide layer and the thin gate oxidation layer on drain/source are etched vertically by a reactive ion etching until the photo-resist and the silicon surface of drain/source are exposed. A plurality of spacers are thus formed on the side walls of the photo-resist/polysilicon gate. Upon stripping the photo-resist, the grooved gate structure is formed on the semiconductor device.

    Abstract: The present invention provides a method for fabrication of polycrystalline silicon thin film transistors, which forms a silicon spacer on the sidewall of the active layer of a thin film transistor (TFT) by way of anisotropic plasma etching in a single direction. The silicon spacer provides a mechanism for laser recrystallization on the sidewall to prevent the active layer from shrinkage or shelling-off after the laser recrystallization. According to the present invention, large grains can be formed in the channel without additional mask during production. By doing so, the characteristics of the components are enhanced; the uniformity is improved; and, the production cost is lowered. Therefore, this technique will play an important role in the fields of low temperature polycrystalline silicon thin film transistor (LTPS-TFT).

    Abstract: A low dielectric constant (k) material, such as methylsilsesquioxane (MSQ), used as an interlevel dielectric is expected to reduce the parasitic capacitance in integrated circuit. However, MSQ film can be easily degraded during resist ashing after the film is etched with the damascene trenches being created. The present invention discloses an innovative sidewall capping technology to solve the degradation issue. Prior to resist ashing, a high-quality, low-k oxide film is selectively deposited onto the sidewalls of MSQ trenches using selective liquid-phase deposition. Experimental results demonstrate that the capping oxide can effectively protect the sidewalls of MSQ trenches from ashing-induced degradation.
