    摘要： A method of depositing layers of intrinsic amorphous silicon and doped amorphous silicon sequentially on a substrate in the same CVD chamber without incurring a dopant contamination problem. The method can be carried out by first depositing an additional layer of a dielectric insulating material prior to the deposition process of the intrinsic amorphous silicon layer. The additional layer of insulating material deposited on the substrate should have a thickness such that residual insulating material coated on the chamber walls is sufficient to cover the residual dopants on the chamber walls left by the deposition process of the previous substrate. This provides a clean environment for the next deposition process of an intrinsic amorphous silicon layer on a substrate in the same CVD chamber.

    摘要： A method of limiting sticking of a body (substrate) to a susceptor after the body has been coated with a layer in a deposition chamber by plasma chemical vapor deposition includes subjecting the coated body to a plasma of an inactive gas, e.g., hydrogen, nitrogen, argon or ammonia, which does not adversely affect the coating and does not add additional layers to the body. After the coated body is subjected to the plasma of the inactive gas, the body is separated from the susceptor.

    摘要： An improved method of depositing films of a gate silicon nitride and an amorphous silicon on a thin film transistor substrate at high deposition rates while maintaining superior film quality is provided. The material near the interface between the amorphous silicon and the nitride are deposited at a low deposition rate which produces superior quality films. The region away from the interface are deposited at a high deposition rate which produces lesser, but still good quality films. By using this method, superior quality thin film transistors can be produced at very high efficiency. The method can be carried out by depositing a high quality g-SiN.sub.x at a low deposition rate on top of an average quality gate nitride deposited at a high deposition rate and then depositing an amorphous silicon layer. It also applies in a process where high quality amorphous silicon is first deposited at a low deposition rate on a gate nitride layer to form an interface, and then average quality amorphous silicon is deposited at a high deposition rate to complete the silicon layer. The unique process can be applied whenever an interface exists with an active semiconductor layer of amorphous silicon. The process is applicable to either the back channel etched TFT device or the etch stopped TFT device.
