The many different technologies available for structuring and the excellent adhesion of ORMOCER®s on various materials (e.g. silicon, SiO2, glass, metals, oxidic and low-cost polymer substrates such as BT and FR4) show that ORMOCER®s are perfectly suitable for applications in microelectronics and microsystem technology.
Their compatibility with traditional thin-film technology, simple means of processing (curing temperatures < 170 °C in standard atmosphere) and the possibility of creating microstructures (e.g. bumps and vias) guarantee maximum flexibility and versatility with respect to locally available technologies, with ORMOCER®s featuring negative resist behavior.
These advantages are completed by the excellent electrical, mechanical and thermal properties of ORMOCER®s:
Dielectric constant: e < 3.2 (10 kHz)
Dielectric loss factor tan d: < 0.004 (10 kHz)
Specific resistance: > 1016 Ohm cm
Dielectric strength: 400 V/µm on Al
Young's modulus: 2.5 GPa (adjustable)
Welding stability: 300 °C / < 30 min
Thermal stability: up to 300 °C (TG/MS, 5% mass loss)
