Abstract

The invention brings forward a pallet, which comprises: a pallet body; a plurality of mounting grooves which are arranged along the circumference of the pallet body; and a plurality of small pallets, each small pallet correspondingly being arranged in one mounting groove, werein the pallet body is composed of an insulating material and the plurality of small pallets are composed of a heat conduction and electrically conductive material. The invention also brings forward chemical vapor deposition equipment with the above pallet. According to the chemical vapor deposition equipment provided by the invention, as the turning radius of induced-current is becoming smaller, the surface temperature of the pallet is more uniform, thus raising temperature homogeneity of a substrate processed by the chemical vapor deposition equipment. In addition, the pallet is simply designed and is easy to realize.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a tray and a chemical vapor deposition device with it. Background technique [0002] The temperature uniformity of MOCVD (metal organic compound chemical vapor deposition), especially the temperature uniformity on the tray carrying the substrate, plays a very important role in the process performance. In order to achieve this temperature uniformity, various manufacturers use different heating methods and corresponding Tray structure. For example, in the reaction chamber of the existing shower head structure, resistance wires are used to heat the entire large graphite tray, and the temperature uniformity of the tray is realized through partitioned resistance wires. The existing planetary structure uses induction to heat the entire large graphite tray, and the large tray carries a small tray that can rotate, and achieves better temperature uniformity in the small tray thr...
