The Answer:

Marktech offers multiple Silicon photodetector types, both standard and custom, supporting a variety of requirements. Each Silicon photodetector type manufactured by Marktech offers its own advantages, of course, depending upon the specifics of the intended installation environment. Firstly, Marktech designs and manufactures standard and Silicon photodiodes and Silicon phototransistors, with spectral sensitivities from 350 nm to 1100 nm, for visible and near infrared applications requiring low noise, high speed and high sensitivity. The company is also offering a new line of UV-enhanced photodetectors, with improved spectral sensitivities in the 150 nm to 570 nm range.

In addition, all of the Silicon wafers and chips manufactured by Marktech are optimized to ensure uniform, consistent performance and high reliability for their intended application. Marktech further offers them with several cost-effective customization capabilities. Just a few examples include operational voltage selection, wavelength specific band-pass filtering, and hybridization.

Marktech also designs and manufactures GaP Schottky photodetectors, specially optimized for high-accuracy UV photodetection up to the visible spectrum, or 150 nm to 550 nm. They also manufacture InGaAs PIN photodiode chips, in active area sizes from 0.1 to 3.0 mm, with spectral sensitivities from 600 nm to 2600 nm. And finally, Marktech offers foundry services for the epitaxial growth of high-reliability SWIR epiwafers, of 1.0 μm to 2.6 μm cut-off wavelength, with InP material as the base substrate. They are offered in 2″, 3″ and 4″ diameters. A little known fact, Marktech remains one of only a few companies in the world offering SWIR.

So, should your Silicon photodetector requirements call for something that’s perhaps more “out of the box” than “off the shelf”, the experienced team at Marktech can help.  Contact Marktech today for an applications assessment.
