China has broken up foreign monopolies of high- performance semiconductor temperature controllers, according to Sun Dongming, a research fellow with the Chinese Academy of Sciences who is also a deputy to the 14th National People's Congress (NPC).

Sun’s team has been working on the research of adjusting the temperature of semiconductor chips and his team researches on micro semiconductor temperature controllers.

The controller can immediately produce the temperature difference of up to 100 C at the moment of getting connected to electricity, and works as an air-conditioner to cool semiconductor chips, according to Sun.

It took only three months to transfer the scientific research results to actual production and the monthly production capacity of the temperature controller has exceeded 300,000 pieces.

Last July, the domestic-developed temperature controller developed by the team was launched to the space with China-developed research rocket and completed the first successful in-orbit verification of 5,000 kilometers in space, Sun said.

It means that China has realized the domestic production of a series of micro semiconductor devices from space grade to industrial grade, breaking the previous foreign monopoly on high-end temperature controller parts, Sun said.

Currently the controllers are widely used in laser communication, vehicles, and biomedicine among other fields.
