Inexpensive silicon based photodetectors for night/thermal vision
Silfrared technology is a monocrystalline silicon based new concept that enhances silicon detectivity in the near and mid infrared range. Silfrared devices are uncooled and fabricated with non-contaminant and abundant elements, being the fabrication procedures easily integrated with CMOS technology. This properties can provide devices over a 20% cheaper than existing technologies. Silfrared will cover market’s demand for inexpensive devices sensible to the near IR and extended to the visible range that have been pursued since the early 90’s.
Silfrared devices are based on the illumination-coupled infrared new concept for silicon photodetectors technology that can provide high response in the near- and mid-IR range (added to visible range) with a monocrystalline silicon based uncooled device.
In contrast to other mid-IR commercial photodetectors (made of materials different from Si) these devices can take advantage of the low price of Si raw material and processing techniques, and of its non-contaminant character. This technology is also fully compatible with traditional Si CMOS technology.
Areas of application are:
“Silfrared concept enhances Si detectivity in the mid-IR range at room temprature, fully compatible with CMOS technology, saving more than 20% of the cost”
“There is a huge underpenetrated market for an uncooled IR photodetector technology based on silicon. Inexpensive devices for the near IR detection extended to the visible range have been pursued since the early 90’s”
