With micro-electric circuits getting smaller and smaller and more efficient, it is necessary to design and apply new components and to develop more energy-saving solutions.
Micro-electronic components can include lithographically produced layers with an amorphous micro-structure up to nanoscale providing essential functions of the component. The lithographic structuring produces properties in the layer material which are reflected in the domain structure, in the magnetizability and the frequency response behaviour.
New passive micro-inductor components were developed in which the magnetic field distribution is – other than in conventional micro-coils - almost parallel to the silicon substrate minimising detrimental screening current losses. The development was founded on iron- and cobalt-based material systems.
The newly developed ferromagnetic layers for semiconductor components are CMOS compatible and suitable for high frequencies. The materials used for the first time provide more energy-saving high frequency circuits.
ADVANTAGES AND BENEFITS
- CMOS compatible layers for semiconductor components
- Ferromagnetic layers suitable for high frequencies
- Layers providing more energy-saving high-frequency circuits and the reduction of detrimental screening current losses
STATE OF DEVELOPMENT
- The feasibility and functionality were successfully demonstrated in a prototype.
