Semiconductor temperature control technology is a key technical method that enables precise temperature regulation of semiconductor devices. It also plays a crucial role in ensuring their quality and productivity. Due to recent trends, there is a growing demand for high-temperature control as well as for uniform and rapid heating solutions in this industry. This is a sector that requires temperature uniformity at operating temperatures higher than those of traditional heating devices.

In the semiconductor field, temperature controllers are used, for example, to regulate the temperature of etching baths in the chemical wet processing of wafers and microchips. Other applications include metal-organic chemical vapor deposition and functional assemblies using thermofluids. Let’s take a closer look !

There is no doubt that semiconductors changed the world beyond anything that could have been imagined
before them.

Semiconductors: Managing Temperature

Many challenges still need to be overcome in the semiconductor sector, which requires high power density and optimized reliability. Overall, thermal management solutions are used in four main types of processes :

  • Diffusion. Under high-temperature conditions, impurity elements are diffused into the semiconductor structure under controlled parameters to modify the material’s electrical properties, improve performance behavior, or form integrated circuits, resistors, and other devices. The temperature response of the diffusion process will directly affect the qualitative and functional properties of the treated materials, and can also help shorten the overall process time.

  • Oxidation. Widely used in basic semiconductor processes, oxidation films can create a barrier layer to prevent ion implantation, provide surface passivation, or serve as an insulating layer, among other functions.

  • Alloying. A low-temperature heat treatment process where silicon wafers are placed in an inert gas atmosphere to stabilize the crystalline structure of the wiring.

  • Annealing. Thermal annealing primarily aims to eliminate lattice defects and repair structural damage to the silicon. Typically, this process is performed either in a furnace—at lower temperatures for longer durations—or using laser or flash lamp annealing, which operates at higher temperatures with superior precision.

 

What are the benefits of thermal management in semiconductors ?                                              

The semiconductor manufacturing environment requires efficient heating and cooling of process fluids and treatment fluids. The facilities are costly and particularly sensitive to dust, vibrations, temperature fluctuations, and humidity. The slightest dust particle or any deviation from the required temperature range can ruin a microcircuit or generate static electricity.

Heating and cooling systems therefore offer numerous advantages:

  • Precise and reproducible temperatures.The semiconductor temperature control system enables precise temperature regulation within a range of ±0.1°C. Combined with temperature detection and control capabilities, it allows for remote control, making it easy to implement an automated control system.
  • Fast heating and cooling.The semiconductor temperature control system has two functions: cooling and heating, and you can switch quickly between the two.
  • High-pressure, high-flow circulation pumps.
  • Operation with non-electrically conductive liquids.
  • High Performance. The semiconductor temperature control system can respond quickly to temperature changes and precisely regulate temperature, allowing the system to maintain stable operating conditions in both high- and low-temperature environments.
  • Energy Savings and Environmental Friendliness. The semiconductor temperature control system does not require the use of traditional refrigerants, which reduces environmental impact and makes the system more eco-friendly.
