Topsil Semiconductor Materials A/S products

Topsil high transmission (HiTran) silicon targets high quality IR applications and instrumentation. Due to its high purity, it has unique transmission performance across most of the infrared band, including the far infrared region. Transmission starts at 1.2 μm. Up to 7.0 μm there are no bulk properties limiting the transmission.

Topsil high resistivity float zone silicon (HiRes™) is well suited for microwave and millimeter wave circuits and devices. It is a good candidate for a GHz IC substrate; that is a substrate for monolithic integration of digital, analog and interface functions on a single chip. It has low oxygen levels and bulk resistivities approaching 70kΩcm.
