Problems solved by technology

[0004] However, with the increase in the size of the epitaxial substrate and the reduction in the size of the light-emitting diode element, the above-mentioned configuration relationship between the carrier and the carrier can no longer meet the temperature uniformity required by the epitaxial substrate during film formation.

Abstract

The invention provides a heating device. The heating device comprises a bearing table, a plurality of carrying discs, a first heater and a second heater; the bearing table is provided with a revolution shaft. A plurality of carrying discs are arranged on the bearing table; the bearing table drives the carrying discs to revolve with the revolution shaft as the center; the first heater is arranged under the bearing table; the first heater has a first width in a radial direction of the revolution shaft; the second heater is arranged under the bearing table; the second heater and the first heaterare separated from each other; and the second heater has a second width in a radial direction of the revolution shaft, and the first width is not equal to the second width. A chemical vapor depositionsystem employing a heating device is also proposed.

Description

technical field [0001] The invention relates to a film forming device, in particular to a heating device and a chemical vapor deposition system. Background technique [0002] As the operational performance and reliability of light-emitting diode materials continue to improve, their application fields are gradually diversified, such as lighting devices, displays, and backlight modules. In order to meet the performance specifications under various usage requirements, light-emitting diode elements of different styles or materials are constantly challenging the design and mass production capabilities of related manufacturers. For example, for micro-LEDs used in displays, the film thickness uniformity of the epitaxial layer needs to reach a certain level to meet the required display quality (such as color rendering or brightness uniformity of the display surface). [0003] Chemical vapor deposition (chemical vapor deposition, CVD) technology is one of the more commonly used tech...
