South Korea's Semiconlight and Huacan Optoelectronics signed a flip-chip patent licensing agreement

According to the agreement, Huacan Optoelectronics will pay patent royalties to Semiconlight for the design and sales of specific LED flip-chips.

Semiconlight said that in October it received a request from Huacan Optoelectronics to obtain flip chip patent licensing rights. After careful review, Semiconlight decided to sign an agreement with Huacan Optoelectronics. According to the agreement, the first royalty payment will be generated within the year.

Semiconlight said that the company's silver-free flip chip is different from the existing horizontal structure LED chips and is a new type of flip chip. This technology inverts the LED chip and directly welds it to the substrate without the need for separate wire bonding. It can be easily applied to ultra-small LEDs and is therefore considered to be an emerging technology for small and micro LEDs. The key technology of LED display. It is currently known that the contract involves approximately 250 globally registered patents related to Semiconlight flip-chip LED chips and their packaging.

In 2016, Huacan Optoelectronics and Semiconlight established a Chinese joint venture "Semiconlight China". In 2019, the joint venture was selected as a government project of the Korea-China Joint International Technology Development Project and will carry out "development and industrialization research on semiconductor micro-LED core technology for next-generation displays" before 2022.
