Inside The Device Fabrication Process

The fabrication of InGaAs pixel array chips for NIR/SWIR imaging involves a series of steps, which includes growing InGaAs on an InP substrate, adding insulating glass, creating pixel electrodes through photolithography, and then inspecting the chips in a cleanroom.

These chips find their application in various fields such as surveillance, night-vision, machine vision, and medical imaging. Sensors Unlimited prides itself on having in-house control over the InGaAs process, thus ensuring top-notch NIR/SWIR technology.
