Main Products Handled
Various targets are available, offering the high purity that makes devices more reliable.
Ti Target
Our TI targets are widely used in places where titanium is necessary in semiconductors, such as barrier layers for Al interconnects, and hard masks. With the presence of Toho Titanium Co., Ltd., manufacturer of high-purity titanium, the Group has a full supply chain from raw material to target.
Features
- We have built up a wide-ranging lineup of different shapes through 20 years of experience.
- Measures are taken to minimize particle levels and shorten burn-in time.
- We have developed materials for high-power sputtering use.
Technology and Properties
Purity 4N5 (Ti 99.995% or above)
5N
5N5
Shapes ---Support for all sputtering equipment and wafer sizes.
SFG and SR made standard specifications ---To minimize particle levels and shorten burn-in time
Uses
- Interconnect barrier
- Hard masks
- Gate electrodes
- UBM
- TSV, etc.
Cu target
Our Cu target, with 6N (99.9999% or above) purity, was specially developed to reduce particulate matter during sputtering. JX Metals encompasses the entire supply chain, from resource extraction, smelting and refining to target manufacturing, enabling reliable supply of our world-standard 6N target.
Features
- High-purity targets are supplied as standard products thanks to in-house smelting and refining.
- Particle reduction is remarkably effective.
- Uniform grain diameter helps stabilize sputtering data.
Technology and Properties
Purity 6N (99.9999% or above). Note that 4N5 product is available for applications other than semiconductor interconnects. All sputtering equipment can be used for any wafer size. Particle suppression is especially effective at reducing O, S, and P impurities.
Applications
- Cu interconnect seed layer
- UBM
- TSV, etc.
Cu alloy target
Exhaustive efforts are made to minimize particle occurrence during sputtering. We use 6N (99.9999%) Cu manufactured at the Isohara Works as the raw material for semiconductor sputtering targets, and a wealth of knowledge about melting with additive metals is incorporated into the processes. Excellent affinity for mass production lets us rapidly launch manufacturing for leading-edge semiconductors using Cu alloy.
Features
- Suppression of particles to a minimum is built into the processes.
- Grain size and alloy composition are uniform on the surface and in the cross-sectional direction.
- We can flexibly respond to requirements for alloy type and composition.
- Support for mass production is outstanding.
Technology and Properties
Alloy types: CuAl, CuMn, etc.
A wide range of requirements for other additive metals and composition can also be met. Feel free to consult with us about requirements for other alloys that do not include Cu.

Applications
- Cu interconnect seed layer for leading-edge semiconductors
Ta target
We perform all processes in-house, from upstream processes including forging and rolling down to target manufacturing, using the purest raw materials in the industry. We are thus able to exercise full control over the grain size and orientation that affect sputtering properties. Armed with these advantages, we can flexibly meet detailed customer requirements for quality, as well as delivery dates.
