Abstract

This invention discloses a wedge reaction pipe used in metal organic chemical gas phase deposition device including a quartz capsule, an induction coil, gas inlet pipe, an escape pipe, a substrate, a graphite boat, an upper flange and a lower flange, among which, the induction coil sheaves the quartz capsule characterizing in mounting a cylindrical mask in the reaction chamber, a baffle isolates the gas inlet cavity into a left and a right inlet cavities, the escape cavity communicates with the escape pipe of the mask. The cylindrical mask of a tilt top plate forms a wedge reaction cavity with the substrate, the inlet is wider than the outlet. A substrate rotation device is also designed here and the lower flange is mounted on the arm of the lifter.

Description

technical field [0001] The invention relates to a reaction tube, in particular to a wedge-shaped reaction tube used in metal organic chemical vapor deposition equipment. Background technique [0002] When using metal-organic chemical vapor deposition equipment (MOCVD) to prepare semiconductor thin film materials, different reaction gases need to be sent into the reaction chamber respectively, and then the reaction gases are mixed on the substrate surface, and at the same time, the gas flow is kept in good condition when flowing through the substrate. Laminar flow state, so as to grow thin film materials with excellent performance. At present, most of the quartz reaction tubes in metal-organic chemical vapor deposition equipment at home and abroad are designed as horizontal or vertical, which is difficult to achieve the purpose of effectively reducing the pre-reaction and mixing the reaction gas evenly. Contents of the invention [0003] The object of the present invention...
