SK Group plans to produce hydrogen fluoride next year(electronics manufacturing expo news)

30 Jul 2019

In response to Japan’s restrictions on exports to South Korea, large Korean electronics manufacturing expo companies are beginning to take action to get rid of Japan. SK Group plans to produce high-purity hydrogen fluoride through its subsidiaries and put it into mass production in the first half of next year.

According to a number of media reports from South Korea's "etnews" and "Korean Daily", SK Group's subsidiary SK Mertials plans to complete prototypes this year to prepare for the production of high-purity hydrogen fluoride. According to SK electronics manufacturing expo Mertials, relevant production equipment is being developed with the goal of providing samples at the end of the year.

Hydrogen fluoride is one of the items in Japan's export restrictions to Korea. 41.9% of South Korea's hydrogen fluoride is imported from Japan, and more than 90% of high-purity hydrogen fluoride (99.999% or more) is dependent on Japan.

Hydrogen fluoride is one of the raw materials for semiconductor material etching gas. In the chip manufacturing process, it is used to describe circuits and clean silicon foreign matter. The gaseous and liquid hydrogen fluoride can be mixed. The liquid product is called etching liquid, and the gaseous state is etching gas.

SK Mertials plans to produce gaseous hydrogen fluoride, an etching gas, which is supplied to the semiconductor industry. "etnews" pointed out that since the electronics manufacturing expo sample will be released at the end of SK, it is expected to be put into formal production in the first half of next year.

SK Mertials has been producing semiconductor materials since 1982. It is the first domestically produced nitrogen trifluoride (NF3) company in Korea. Nitrogen trifluoride is one of the raw materials for semiconductors, displays and solar cells. It also produces industrial gas tungsten hexafluoride. (WF6), supplied to the petroleum industry and steel industry.

Although SK Mertials has extensive manufacturing experience, the first production of hydrogen fluoride has attracted attention. SK electronics manufacturing expo Mertials said that it has handled raw material fluorine in the past and accumulated a lot of relevant manufacturing experience, and has the strength to manufacture high-purity hydrogen fluoride.

SK Matials has not yet announced details such as the size of the investment, production capacity (CAPA), and the quality of the product. It is still unknown whether it can be applied to the semiconductor process.
