摘要: A vapor deposition apparatus for depositing thin film on substrates in which solid starting materials are used. In this apparatus, a carrier gas flows up and down in the same direction as gas convection, such that the effect of gas convection is minimized and film thickness and impurity concentration are uniform over the substrate surface. This uniformity is achieved by orienting a main reaction tube in a vertical direction, attaching two branch reaction tubes at the top of the main reaction tube, and venting carrier gas out the bottom of the main reaction tube. Alternately, the main reaction tube can be oriented horizontally, with the substrates being carried on a holder within a container having pores on its top and bottom.

摘要: Disclosed is an improvement of the chemical vapor deposition (CVD) process for preparing an electroluminescent device having a large area and a large size. The process includes forming a luminescent layer on a substrate by a reduced-pressure chemical vapor deposition method wherein a source material gas is introduced into a reaction chamber. The reaction chamber includes a screening means which screens the source material gas flow in the chamber to form a first area in which the gas is flowing and a second area in which the gas substantially does not flow. The screening means has apertures for connecting the first area and second area. the substrate is placed in the second area, to which the source material is supplied by means of gas diffusion.
