Our Business

We develop and produce of various “Semiconductor Packages” adapting for the miniaturization, acceleration, and performance enhancement of semiconductors.

We aim to enrich and contribute to the lives of people all over the world through providing our cutting-edge packaging technologies, including for markets related to IoT and AI, which are anticipated to become more widely used in the future, and auto market, in which technology development is accelerating, such as autonomous driving and electrical vehicles, supported by the practical implementation of the next-generation mobile communication standard (5G).

Our Products

We provide products and services that meet the needs of the market, with the central focus being semiconductor packages based on a variety of elemental technologies we have accumulated since the founding of our company.

Flip-Chip Type Packages

Also called build-up substrates or flip-chip packages, they mainly see use in advanced IC chips such as CPUs for computers and servers. These packages meet the need for high-speed and high-density semiconductors through fine wiring patterns, multilayered structures, and superior electrical characteristics.

Plastic-BGA Substrates

These substrates are mainly used in memories, controllers, and automotive applications. Fine wiring patterns and multilayer structures support the miniaturization, densifying, and thinning of semiconductors.

IC Assembly

We perform IC assembly (packaging) for mounting IC chips in packages. We meet the needs of our customers through advanced internal connection technology compatible with a variety of packaging types.


Our Leadframes are manufactured with stamping technologies using extraordinarily precise dies and various plating technologies. These Leadframes see use in wide range of applications, such as in smartphones, PCs, automotive and consumer electronics, and more. We produce not only stamping Leadframes but also etching lead frames to meet a variety of needs.

Glass-to-Metal Seals

Glass-to-metal seals are mainly used for laser diodes and sensors for in-car use. Its high hermeticity and superior electrical characteristics meets the needs of fields that demand a high degree of reliability.

Heat Spreaders

Used in CPUs found in PCs and servers. Through excellent stamping process and plating technologies, heat generated by IC chips is efficiently and quickly dispersed, ensuring stable operation and function.

Ceramic Electrostatic Chuck

Ceramic electrostatic chuck sees use in etching machines for semiconductor manufacturing equipment. We respond to the advanced needs of our customers through ceramic manufacturing technology we have cultivated over the years.

Our Target Markets—An Active Yet Unseen Role—

Electronic products, such as PCs, smartphones, and other home electronics with various functions that incorporate advanced semiconductors, are used for people’s abundant lives and have become indispensable to our society. Semiconductors are expected to greatly spread the usage continuously as a key technology such as in automobiles, in which technological development is accelerating, including with autonomous driving and EV (electric vehicles), and applications related to the IoT and AI, which is envisioned to expand rapidly in the future.The semiconductor market is anticipated to keep glowing.
With our wide range of products and various technologies, we cover the entire semiconductor packaging area to become unparalleled in this industry, and we provide our products and services to a variety of markets.
