    摘要: We have discovered that controlling a combination of PECVD deposition process parameters during deposition of silicon-containing thin film provides improved control over surface standing wave effects. By minimizing surface standing wave effects, the uniformity of film properties (particularly film thickness) across a substrate surface onto which the films have been deposited is improved.

    摘要: Methods for depositing a gate insulator layer and a semiconductor layer onto a large area substrate with improved film uniformity, device mobility and stability are provided. The film properties of the gate insulator layer and the semiconductor layer are selected so that higher electron mobility (greater than 0.7 centimeters squared per voltage per second) is obtained, thereby efficiently enhancing the performance and stability of TFT devices. Improvements in film uniformity may also be realized.

    摘要: A method and apparatus for depositing a material layer onto a substrate is described. The method includes placing the substrate in a process chamber, delivering a mixture of precursors for the material layer into the process chamber, delivering a hydrogen gas into the process chamber to improve water-barrier performance of the material layer, controlling the temperature of the substrate to a temperature of about 100° C. or lower, applying an electric field and generating a plasma inside the process chamber, and depositing the material layer on the substrate. The material layer can be used as an encapsulating layer for various display applications which require low temperature deposition process due to thermal instability of underlying materials used. The encapsulating layer thus deposited provides reduced surface roughness, improved water-barrier performance which can be applied to any substrate type including wafer, glass, and plastic film (e.g., PET, PEN, etc.) and any substrate size in the flat panel industry.
