Hubei Dinglong Holdings has announced an investment of USD 113 million to establish a factory that will produce KrF and ArF photoresists, key materials in the manufacture of advanced integrated circuit chips. This move is seen as a significant stride towards making China’s chip manufacturing industry more self-sufficient.
The factory will be situated in Qianjiang, in the central Hubei province, and is expected to produce 300 tons of KrF and ArF photoresists annually, according to the Chinese semiconductor chemicals supplier. KrF photoresists are primarily used in 130 nanometer and 250 nm chips, while ArF photoresists are used in 14 nm and below semiconductors.
Dinglong believes that if it can mass-produce ArF and KrF photoresists and establish a strong customer base, it will yield substantial economic benefits, given China’s reliance on imports. The Wuhan-based company has already developed 13 types of ArF and KrF photoresists, five of which are currently being tested by clients.
The investment, construction, and operations of the project will be managed by a joint venture set up by Dinglong. Dinglong will hold a 75% stake in the JV, with 20% owned by two companies associated with key staff, and the remaining 5% held by an external investor. The timeline for the construction has not been disclosed.
The IC photoresist market in China grew by 13.5% last year to USD 470.8 million and is projected to reach USD 527 million by 2025, according to data from the China Electronics Materials Industry Association cited by Dinglong. The KrF and ArF photoresist markets are expected to account for USD 347 million of this.
As of 1.37 p.m. today, Dinglong’s shares [SHE:300054] were trading at USD 3.20 per share, a 0.7% increase.
