High-end MEMS-based infrared emitter with black silicon emission layer for NDIR gas analysis in the long wave range for demanding medical and industrial applications. High-end MEMS-based infrared emitter with black silicon emission layer for NDIR gas analysis in the long wave range for demanding medical and industrial applications. By implementing a sophisticated micro-nanostructured silicon metal emission layer on a MEMS hotplate transmitter chip, Micro-Hybrid offers infrared sources with true blackbody radiation characteristics. The exceptionally high performance IR transmitter MEMS chips are defined by heating plate temperatures up to 850 °C in combination with a broadband spectral emission coefficient Ɛ fast 1. This enables highest radiation intensities over a wide infrared wavelength range. In addition to the high infrared output intensity, the focus of our successful development was on long-term stability.
JSIR 360 sources are available in different TO packages with cap or reflector as well as in SMD packages. Various backfill gases in hermetically sealed TO packages ensure highly efficient versions and lower power dissipation, e.g. for battery-powered applications. The MEMS chip used in our infrared emitters consists of a multilayer heating plate membrane containing a high-temperature stable metal heating layer and advanced silicon-metal micro-nano-structured surfaces. A final passivation layer guarantees long-term stability of the emission behavior at heating plate temperatures up to 850 °C. The emitter chip is based on a silicon substrate with a backside etched membrane. All thin film processes are performed with CMOS compatible materials.
