Abstract

The invention discloses a CVD (chemical vapor deposition) pipeline and a CVD device with the same. The CVD pipeline is used for supplying gas to be used in a CVD process, and a heating device is arranged on the wall of the CVD pipeline. A pneumatic valve of the gas in an Alkyl H2 pipeline is frequently opened and closed, so that an MO (molybdenum) source is attached to the inner wall of the Alkyl H2 pipeline. Therefore, the heating device is additionally arranged on the wall of the CVD pipeline, the wall temperature of the CVD pipeline can reach a certain temperature, the MO source is constantly kept in a stable state and cannot be attached to the wall of the CVD pipeline, the MO source possibly attached in the prior art cannot be carried into carrier gas at a certain node, and a coating on the surface of a product is uniformly distributed.

Description

technical field [0001] The invention relates to a CVD pipeline and a CVD device with the same, in particular to a high-yield CVD pipeline and a CVD device with the same. Background technique [0002] Light Emitting Diode (LED for short) has the advantages of high luminous intensity, high efficiency, small size, and long service life, and is considered to be one of the most potential light sources at present. In recent years, LEDs have been widely used in daily life, such as lighting, signal display, backlight, car lights and large-screen display and other fields. In industry, metal organic compound chemical vapor deposition (MOCVD for short) equipment is usually used for growth. [0003] In the current mass production process of MOCVD in the semiconductor industry, it often happens that due to the unstable gas flow, unnecessary doping in the gas is brought into the reaction chamber to participate in the reaction, which leads to uneven distribution of the coating on the surf...
