Sanan Optoelectronics will begin construction of 6-inch Micro LED wafer production lines

At the beginning of this year, Sanan Optoelectronics who is the largest LED chip provider in China announced that its Micro LED and Mini LED chip production lines are under construction. At the end of this year, it is reported that Sanan will start the production of 6-inch Micro LED wafer.

Sanan has developed Micro LED chips of 10*20 μm ,it is aiming to further reduce the chip size in 2020, providing testing data and samples to its clients. Production of 6-inch wafer is a very important step for Micro LED cost reduction as currently most of the Micro LED technology producers adopt 4-inch Micro LED wafers for research and pilot production.

The Chinese LED chip maker reported that it has invested RMB 12 billion (US$1.72 billion) in Micro LED and Mini LED wafer and chip production in April 2019. It is anticipated that its annual production capacity will be up to 1.61 million GaN epitaxial wafers and 750,000 GaAs wafers. 

According to a news report from Digitimes, Sanan focuses small size displays on wearables in the beginning because the transferring chips are in smaller quantity. When the mass transferring technology becomes more mature, the technology would be used for larger size displays.
