How to choose an RTP rapid annealing furnace?

When selecting an RTP (Rapid Thermal Processing) rapid annealing furnace, multiple factors need to be comprehensively considered to ensure that the selected equipment can meet production needs and improve production efficiency. Here are some key purchasing points:

1. Clarify application requirements
Process requirements: Firstly, it is necessary to clarify the main uses of RTP rapid annealing furnaces, such as CMOS device backend process, GaN film preparation, SiC material crystal growth, etc. Different application requirements correspond to different device specifications and functions.
Workpiece characteristics: Consider the size, shape, and material of the workpiece to ensure that the heating area and capacity of the annealing furnace can meet production needs.

2. Technical performance evaluation
Heating rate and temperature uniformity: A fast heating rate and excellent temperature uniformity help improve production efficiency and product quality. It is necessary to pay attention to the actual heating rate of the equipment and the uniformity of temperature in different areas.
Temperature control accuracy and stability: Temperature control accuracy and stability are crucial for precise control of the heat treatment process. Equipment with high-precision and high stability temperature control systems should be selected.
Maximum temperature: Understand the maximum operating temperature of the equipment to ensure it meets process requirements. Meanwhile, attention should be paid to the overall stability and durability at the highest temperature.
Cooling speed: The cooling speed of a rapid annealing furnace is also an important indicator. Pay attention to the gas flow control method and accuracy of the cooling atmosphere, as well as the safety measures of the gas cooling system.

3. Equipment quality and after-sales service
Manufacturer: Choose well-known brands and suppliers with good after-sales service. The quality of equipment and after-sales service level can be evaluated by understanding the manufacturer’s technical strength, market share, user evaluation, and other aspects.
Manufacturing process and materials: Check the manufacturing process and materials of equipment, such as heating elements, insulation materials, etc., which directly affect the performance and service life of the equipment.
Energy consumption and environmental protection: Considering the energy consumption level of equipment, choosing an energy-saving annealing furnace can help reduce production costs. At the same time, pay attention to the environmental performance of the equipment, such as exhaust emissions, noise, etc., to ensure that the equipment complies with relevant environmental regulations.

4. Safety performance
Safety protection measures: The rapid annealing furnace should be equipped with comprehensive safety protection measures, such as emergency switch, furnace wall high temperature alarm, chamber safety valve and cabin door misoperation alarm, etc. The more safety measures there are, the higher the safety factor of the equipment.
Convenience of operation: Consider the convenience of device operation, including whether the operating interface is friendly, whether operation manuals and training services are provided, etc. This will help solve problems and improve operational efficiency during use.

5. Cost performance evaluation
Comprehensive evaluation: In the selection process, it is necessary to comprehensively evaluate the performance, quality, after-sales service and other factors of the equipment, and choose products with high cost-effectiveness. Don’t just pursue low prices and overlook the performance and quality of the equipment.
On site inspection: If conditions permit, it is recommended to visit the equipment manufacturer or user’s site for inspection and trial, in order to have a more intuitive understanding of the performance and effectiveness of the equipment.

In summary, selecting an RTP rapid annealing furnace requires comprehensive consideration of multiple factors. By clarifying application requirements, evaluating technical performance, examining equipment quality and after-sales service, paying attention to safety performance, and conducting a comprehensive cost-effectiveness evaluation, one can choose an RTP rapid annealing furnace that is suitable for their own production needs.
