OUR SERVICES


With a constant drive for miniaturization, higher speed and lower cost, chip manufacturing is an ongoing challenge that pushes the engineering envelope. For the entirety of our history, semiconductor production equipment has been one of our strong suits. Both in front-end and back-end as well as in metrology and measurement tools. We have a long track record, developing and realizing customized modules and machines for many of the world’s biggest OEM’s in semicon equipment. Our scope stretches from positioning and deposition modules to mask and wafer inspection tools, extending to advanced packaging solutions.
We offer end-to-end engineering as a service for semicon manufacturing equipment, from early-phase research and concept development to prototyping, validation and production. Customers can pick and choose the extent of our involvement. We will balance out performance, cost of ownership and time to market, according to your specific demands.

Electromagnetic actuators are an important actuation tool to achieve positioning precision on the nanometer scale. In this realm Lorentz actuators are the mostly used, due to their linear dependence between actuation force and applied current.

The performance of precision mechanisms can be limited by disturbing vibrations that are amplified at parasitic eigenfrequencies. Piezoelectric patches that are integrated into flexures have been shown to be a promising approach for actively suppressing parasitic modes.
