Strengthening its capacity to produce high-performance copper bonding wires
TANAKA Holdings Co., Ltd. (Head office: Chiyoda-ku, Tokyo; Representative Director & CEO: Koichiro Tanaka) has announced that its subsidiary TANAKA Denshi Kogyo K.K. (Head office: Kanzaki-gun, Saga; Representative Director & President: Shigeru Iseki), which is engaged in the production of various types of bonding wires, will establish a new plant in Kaohsiung City, Taiwan, for the production of high-performance palladium coated copper bonding wires (“PCC wires”). The plant is scheduled to commence operations in the first half of 2022.

Construction of this new plant forms part of TANAKA Denshi Kogyo’s plans to increase its production capacity for PCC wires by approximately 1.5-fold by 2025 in order to meet the growing global demand for semiconductors.
TANAKA Denshi Kogyo has been producing PCC wires at its subsidiary in Taoyuan City, Taiwan, since 2011, while it also operates a technical support base in Kaohsiung City. The company is now building a third Taiwanese base so that it can establish stable supply systems capable of meeting the growing demand.
Bonding wires are high-purity metal wires that connect semiconductor devices to lead electrodes. Previously, bonding wires were largely made of gold. However, the use of semiconductors has increased as they are being used not only in computers, mobile phones, and other electrical products but also in household appliances and automobiles. As the number of commonly used electrical devices containing semiconductors has increased, demand has grown for more affordable PCC wires that perform similar to gold bonding wires.
The COVID-19 outbreak has upset the balance of global supply and demand for semiconductors, resulting in a worsening shortage of semiconductors. Bonding wires are an important peripheral material for the semiconductor industry, and establishing systems for the stable supply of high-quality bonding wires has become a matter of urgency.
TANAKA Denshi Kogyo is a leading manufacturer of bonding wires and intends to contribute to the semiconductor industry by supplying countries around the world even in states of emergency.
