TOKYO (Reuters) - Japan has seen its share of the semiconductor market fall from 50% in the late 1980s to about 10% but still hosts some of the most advanced chipmaking equipment manufacturers, making it relevant to U.S. attempts to curb technology exports to China.
The United States in October imposed restrictions on shipments of chipmaking tools to China to slow advances in its chip industry and ultimately its military, and has been seeking the cooperation of major chipmaking peers Netherlands and Japan.
On Friday, Japan said it would restrict exports of 23 types of chipmaking gear, though without specifying any country.
Equipment subject to the curbs includes tools for cleaning and forming layers on the surface of silicon wafers, as well as equipment used in production based on cutting-edge technology known as extreme ultraviolet lithography.
Here are some of Japan's leading manufacturers of tools used to make semiconductors.
TOKYO ELECTRON LTD
Tokyo Electron is the world's third-largest supplier of semiconductor manufacturing tools after Applied Materials Inc of the United States and ASML Holdings NV of the Netherlands. It also makes flat panel display-making gear.
The firm in November slashed its sales forecast for the year to March 2023 by 250 billion yen ($1.88 billion), or 10.6%, due in part to tightening U.S. export curbs to China, though it later raised its revenue outlook by 70 billion yen.
In October-December, its chip equipment sales in China fell 22.3% from a year earlier to 102.7 billion yen, accounting for 22.4% of its total chip equipment sales in the quarter.
"We will respond appropriately after verifying the contents of the curbs," a spokesperson said.
ADVANTEST CORP
Advantest is a chip-testing equipment maker, in competition with U.S.-based Teradyne Inc.
China became the largest market for Advantest in October-December, surpassing South Korea and Taiwan, with the country accounting for 32.9% of global sales in the quarter.
"We see little risk of U.S. export restrictions on China directly preventing us from selling our testers," an Advantest executive said in January.
"However, we could potentially be indirectly impacted as those restrictions put a halt to supplies of other companies' production equipment, prompting our customers to revisit their business plans," the executive said.
On Friday, a company spokesperson said the firm would conduct fair transactions in line with government policy.
SCREEN HOLDINGS CO LTD
Screen is the world's largest manufacturer of equipment used to clean silicon wafers.
