TomoSemi: Semiconductor Laser diode manufacturing tools from Japan

Tools for laser diode manufacturing, such as tools for scribe & break, stacking, mirror coating, testing and optical inspection. We also offer oxydization tools and magnetron sputtering.

For laser diode and photonics component manufacturing

Scribe And Break

Such as diamond scribers, laser scribers and breakers from OPTO SYSTEM to singulate bars and dies from a wafer.

Bar Stacking

Stackers from OPTO SYSTEM pile up semiconductor bars to access bar facets for plasma treatment and coating.

Optical Inspection

Full automatic optical inspection tools from OPTO SYSTEM to sort out defects that can be identified visually.

Thin Film Coating

Electron resonance cyclotron plasma coating for laser diode mirror coating and other thin film applications in which homogeneous layers are needed.

Testing And Probing

Full automatic high speed wafer probers, chip testers and bar testers from OPTO SYSTEM for full automatic characterization and sorting of opto-electronic devices.

Some of the most recognized equipment providers for the semiconductor industry are from Japan but distance, language and culture differences can be a barrier.​

We help build the bridge.
