(Yicai) Dec. 3 -- Several Chinese semiconductor firms, including Naura Technology Group and Hwatsing Technology, targeted by the United States' latest tightening of export controls, assert that the impact will be manageable.

"We expect the impact to be relatively small," a representative from Naura, which manufactures semiconductor production equipment, said to Yicai. In recent years, the Beijing-based firm has focused on supply chain control and development, with 90 percent of its revenue currently derived from the domestic market.

A bureau under the US Department of Commerce unveiled a new wave of export controls yesterday, adding 136 Chinese firms to the so-called Entity List to limit their capability to produce advanced-node semiconductors that might be used in smart military applications or threaten US national security.

Yicai learned that most of the 136 firms are producers of semiconductor manufacturing equipment, including processes such as coating and developing, etching, thin film deposition, cleaning, stripping, ion implantation, chemical mechanical polishing, and packaging and testing.

Hwatsing, another maker of semiconductor production tools, told Yicai that the latest US measures would hardly affect the firm based on its current assessment. The company has gained independent control over most of its core components and established stable supplier relationships. Hwatsing will continue to monitor the situation and maintain communication with both suppliers and customers.

Piotech, which makes products such as plasma-enhanced chemical vapor deposition equipment, said that its inclusion in the US Entity List would have minimal impact on its operations. "Our primary sales area is within China," the Shenyang-headquartered firm told Yicai. “Moreover, for key components and materials, we have multiple supply sources and maintain a certain inventory to ensure supply chain stability.”

Nata Opto-Electronic Material, a producer of high-purity electronic materials, stated that being added to the Entity List does not substantially impact the firm. While it might affect the procurement of some parts, Nata has inventory and plans to replace products with domestic alternatives. Currently, the majority of the company's raw materials are domestically sourced.

Empyrean Technology announced today that it is actively addressing the situation after the electronic design automation firm and its subsidiaries were added to the list.
