Semiconductor Fabrication and Tanaka Precious Metals Group- Relaying electrical connection technology -

Since the company was founded in 1885, TANAKA has worked as precious metals professionals alongside Japan’s manufacturing industry.

Overview

Tanaka Precious Metals Group is quite unique globally as a precious metal manufacturer dealing with most precious metal materials used in semiconductors. Its history in that regard began in 1964 when it became the first Japanese producer of Au (gold) wires used for mounting semiconductor chips. Since then it has contributed to the progress of semiconductor technology throughout the world.

Semiconductor Fabrication Process and Our Products

Semiconductor Fabrication Process and Our Products

Precursor

We develop precious metal CVD/ALD precursors with a focus on ruthenium, and supply high purity precursors suited to the required purposes. Furthermore, we can recycle unreacted precursors without returning them to their original metals, reducing material costs including costs associated with precious metal bullion and precursor fabrication (patented process).

Sputtering Target

Using our melting and sintering technologies, we supply target materials in various shapes and dimensions. In addition to used targets, we also recycle precious metal from equipment and jigs.

Plating

We provide plating with properties according to the application and low-cost processes with high productivity. We also supply various types of wafer plating equipment for needs ranging from mass production to experimental and small-lot production, focusing on matching with chemical processes.

Probe Pin

We provide probe pins which utilize the stable environmental resistance and electrical properties of platinum wiring.

Bonding Wire

We are the largest supplier of bonding wire worldwide. With a lineup including gold, copper, silver and aluminum wires, we supply reliable products at the forefront of the constantly evolving semiconductor technology.

Adhesive for Die-bonding

We offer a wide range of precious metal pastes, powders and conductive adhesives used in circuits and semiconductor die bonding. Also, our fine-tuned technologies enable us to deliver optimum quality in precision circuits.

Sealing material

We provide an extensive range of products for connecting and hermetic sealing of precision parts.

Precious Metals Recycle

Recycling of precious metal is effective at all stages and scrap containing precious metal is considered to be a valuable asset. This kind of scrap can be recycled without being influenced by fluctuations in the precious metals market or differences (spread) between selling and buying prices. Recycling also contributes significantly to reducing costs.
