Our Products
Overview
We manufacture semi-insulating and semiconducting III-V substrates for high-frequency and optoelectronic applications.
Freiberger has established a worldwide reputation as supplier of products that meet highest quality standards.
In our elaborate analysis and measuring processes all products undergo a comprehensive characterization enabling us to meet the customer requirements.
Our GaAs, InP and GaN wafers are based on single crystals that are grown from the melt using the LEC or VGF process or from the gas phase using HVPE technology. The required electrical properties are obtained by adding dopants. The result is n-type or p-type high-resistance (>10⁷ Ωcm) or low-resistance (<10⁻² Ωcm) semiconductors. The wafer surfaces are epi-ready (extremely low contamination) i.e. their quality is suitable for direct use in epitaxy processes.
